Clinical laboratories continue to test sample delivery by drone as a viable alternative to ground transport
In Switzerland, another clinical laboratory drone delivery service recently launched and it has several unique capabilities. This new pilot project to test the delivery of medical laboratory samples by UAV (unmanned aerial vehicle, aka drone) is being conducted by the Dr. Risch laboratory group and start-up drone company Jedsy.
What makes the Risch/Jedsy drone delivery service unique when compared to other drone delivery services is their drone’s capability to deliver directly to windows, regardless of where that window is. This, according to a Jedsy news release, “makes the transport of samples faster and more environmentally friendly.”
Dr. Risch group has 14 clinical laboratories and eight sample collection locations throughout Switzerland. The Swiss Federal Office of Civil Aviation (FOCA) approved Dr. Risch’s first flight between its lab in Vaduz, the capital of Liechtenstein, to its lab in Buchs St. Gallen, sUAS News reported. Risch began transporting lab samples between those locations on an experimental basis in December of 2022.
The Jedsy glider, as the drone is called, has a distinctive vertical takeoff, hover, and landing capability. Once it achieves a safe altitude, it transitions to forward flight and can travel at speeds up to 150 kilometers per hour or about 93 miles per hour.
All systems on the Jedsy drone are redundant and developed to be fail-safe. A human drone operator follows the flight visually via a livestream connection. Once the drone approaches a building for landing, with the exception of the docking station the entire surrounding area is blurred to ensure the privacy of nearby individuals.
The Jedsy Glider (above) is quieter than other multicopters, according to Jedsy, and is able to dock outside a window or balcony. This enables the convenient loading and unloading of clinical laboratory specimens in any type of weather. The docking station also serves as a charger for the drone’s battery to ensure the craft is available for use at any time.

Why Transport Clinical Laboratory Samples by Drone?
“The last two years during the COVID-19 pandemic have shown convincingly how important this service is for the healthcare sector,” explained the medical laboratory group’s founder and CEO, Martin Risch, MD, in the Jedsy press release.
Risch envisions a need for drones in certain medical situations. Dr. Risch currently employs about 50 courier drivers who transport by ground medical samples to regional medical laboratories throughout Switzerland every day.
“If, however, the courier vehicles are stuck in traffic or if they are driving during rush hour, the planned daily routine regarding the analysis and the medical diagnosis is delayed. We hope that this will allow us to offer an even better service, which will ultimately benefit the patients,” Risch stated.
Jedsy has already utilized its glider drone successfully in Africa to deliver laboratory specimens and medicines to remote locations and looks forward to its continued benefits.
“With the new drone, we have already gained important flying experience in Malawi, where over 5,000 flights have been performed as part of the UNICEF drone corridor,” said aerospace engineer Herbert Weirather, founder and CEO of Jedsy, in the press release. “Health centers have already been supplied with critical medicines by Jedsy and the service is being expanded continuously,” he added.
Use of Drones to Deliver Clinical Laboratory Samples Growing Worldwide
Utilizing drones to deliver medical supplies and laboratory specimens is not a new concept and has been tested several times in the past. Dark Daily has previously reported on some of the projects that have been attempted.
The use of drones to deliver clinical laboratory specimens is a rising trend that could be extremely beneficial for healthcare systems, medical professionals, and patients. A number of clinical laboratories in the US and around the world have initiated drone pilot programs, however, there has been little follow-up press coverage about either the success of these efforts or whether they continue to operate.
Nevertheless, faster delivery of laboratory specimens can lead to more timely diagnoses which can potentially lead to better patient outcomes. In the future, it’s likely more clinical laboratories will receive specimens via drones.
Drone program will enable delivery of medical laboratory samples during the day, rather than just at night, allowing daytime sample processing that will increase efficiency and shorten time to results
Healthcare network clinical laboratories continue to explore the use of unmanned aerial vehicles (UAVs), commonly known as drones, to safely deliver medical supplies and clinical laboratory specimens between locations. Dark Daily has covered several similar pioneering drone programs taking place around the world in recent years.
The latest medical laboratory company to launch a drone delivery program is Interpath Laboratory, an independent full-service medical laboratory in the Pacific Northwest.
In partnership with Arizona-based Spright—the drone division of Air Methods, a patient transport company with 300 bases in 48 states—Interpath recently announced the launch of its drone delivery pilot program for delivering lab testing specimens from Yellowhawk Tribal Health Center to Interpath’s medical laboratory in Pendleton, Oregon.
The two organizations hope the initiative will expedite the turnaround time needed for test results, thus allowing for timelier diagnoses and improving patient care and outcomes.
“Many communities located in remote or rural areas lack timely and convenient access to essential medical supplies and service,” said Joe Resnik (above), president of Spright in a press release. “We look forward to this proof-of-concept, showcasing drone delivery’s ability to solve many of healthcare’s existing access and efficiency challenges, while also improving patient care and experience.” (Photo copyright: KVS Technologies.)
Replacing Automobile-based Medical Laboratory Specimen Delivery
“If this pilot program is successful and we are able to utilize this service, our patients have the opportunity to benefit from more rapid test results and access follow-up medical procedures and services,” stated Aaron Hines, CEO of Yellowhawk Tribal Health Center in a press release. “This project could help us further our mission of providing high-quality, primary healthcare for the Confederated Tribes of the Umatilla Indian Reservation (CTUIR).”
Currently, patient samples taken throughout the day at various Yellowhawk facilities are picked up and delivered to Interpath’s clinical laboratory in the evening via gasoline-powered vehicles. A successful drone service would allow lab test specimens to be repeatedly picked up and delivered to the lab for analysis throughout the day.
“Medical laboratory services in rural areas frequently must invest intensive time and resources into sample pick-up,” said Tom Kennedy, president of Interpath Laboratory, in the press release. “We anticipate Spright’s drone delivery service will alleviate many of the drawbacks and costs associated with automobile-based delivery. This initiative represents an example of our embrace of innovative solutions that provide more efficient and effective services to our clients.”
In February, Spright held test flights that transported clinical laboratory specimens from Yellowhawk Tribal Health Center to Interpath’s main medical laboratory in Pendleton, Ore. The 15-mile flight used a Wingcopter 198 drone (above) which employs beyond-visual-line-of-sight (BVLOS) technology. Manufactured in Germany, the Wingcopter 198 has a wingspan of five feet ten inches and can carry up to 13 pounds. It has a range of 46 to 68 miles, and a maximum speed of approximately 62 to 90 miles per hour, depending on the weight of its load. (Photo copyright: sUAS News.)
Other Clinical Laboratory Drone Deliver Programs Worldwide
Innovative approaches, such as the utilization of drones to make clinical laboratory specimen deliveries, can help circumvent many of the challenges in delivering healthcare to rural areas. But UAV delivery networks work equally well for faster specimen transferals in urban environments as well, leading to timelier diagnoses of diseases and ultimately to better patient outcomes.
Goal of university’s yearlong CHURP test was to validate the use of unmanned aircraft systems (UAS), commonly known as drones, in the delivery of medical supplies across SUNY’s campus
Just as hospital systems worldwide are exploring the feasibility of using drone technology to deliver clinical laboratory specimens and medical supplies between healthcare settings and medical laboratories, SUNY Upstate Medical University also has joined the growing list of healthcare providers that have added unmanned aerial vehicles (UAVs), or drones, to their specimen/supplies delivery services.
Traditional delivery of similar items normally takes about seven minutes. The drone delivered the same test kit in just two minutes, according to Government Technology(GT).
Then, “To prove that drone deliveries can be scaled up, the team conducted more medical deliveries in three locations throughout Syracuse two weeks ago, sending supplies from the hospital to a medical laboratory, from the hospital to a surgery center, and from a pharmacy to a second hospital,” GT reported.
Tony Basile, Chief Operations Officer at NUAIR, told GT the flight was a “proof of concept demonstration to show that medical deliveries can be made by drone when speed is essential, such as when tissue samples taken from a surgery patient must be delivered rapidly to a laboratory in a different building.”
Special FAA Waiver Allows Drone Flights Over Certain People
The FAA’s 107.39 waiver allows a drone operator to fly over people who are not participating in the operation and over those who are not covered under a structure or within a stationary vehicle. The January flight marked the first time the FAA’s 107.39 waiver was used for such a drone operation, a DroneUp press release notes.
The SUNY and the NUAIR alliance began formulating the concept of using drones to make medical deliveries more than a year and ago. At that time, there were concerns that a nearby highway project would disrupt normal clinical laboratory specimen delivery operations. The highway separates the hospital from a surgery center and finding a way to expedite deliveries despite slow traffic was essential, GT reported.
“They’re not going to want to wait 20 minutes for a tissue sample to get to the lab because the highway is coming down,” Basile told GT.
Challenges Encountered with Drone Delivery of Clinical Specimens and Supplies
In late spring, the team conducted additional deliveries to further prove the efficacy of using drones to transport medical supplies. They successfully transported supplies via UAV from the SUNY hospital to a clinical laboratory, from the hospital to a separate surgery center, and from a pharmacy to another hospital in the area.
“We conducted 52 successful deliveries throughout the week and were able to streamline the process, getting to about five deliveries an hour,” Basile wrote in a NUAIR article he penned, titled, “Making Drone Deliveries Scalable and Economically Viable.”
The drone used during the NUAIR test flights was equipped with a parachute in case of a mechanical failure and was only flown late at night. Basile believes the FAA will likely require medical delivery drones to have six to eight motors (shown above) as a security measure in case one or two motors fail. A common type of drone, known as a quadcopter, has only four motors and it is unable to fly if even one motor fails. (Photo copyright: NUAIR.)
Although the unmanned delivery flights were successful, SUNY experienced challenges with using drones to make medical deliveries. Those challenges included:
Economics: The NUAIR test flights required five people to conduct the flights, which is more costly than paying one driver to deliver the supplies.
FAA restrictions: The FAA currently does not allow biohazardous materials or controlled substances to be transported by drones due to the risk of public exposure if a crash occurs.
Device approval: The FAA is still in the process of evaluating which drone models will be permitted to carry medical supplies.
Weather: Drones cannot fly in inclement weather conditions.
“[Drones] are susceptible to strong winds and icing,” Basile told GT.
However, Basile believes that with more research and test flights the challenges will be resolved, and that drones will be used for medical deliveries in the future.
“I think they’re certainly going to be used,” he told GT. “Whether it’s soon depends on what you mean by soon.”
Drones Deliver Clinical Laboratory Specimens and Medical Supplies Worldwide
Other countries are increasingly using drones to deliver COVID-19 test kits and samples to and from remote areas.
In 2018, Dark Daily reported on automated logistics company Zipline’s use of fixed-wing drones called “Zips” to provide on-demand access to vital blood supplies in Rwanda and Tanzania. The Silicon Valley company transported more than 5,500 units of blood in 2017 to 12 regional hospitals from a base in the east of Rwanda, reported The Guardian. Zipline began operating in the African nation in 2016 and quickly cut blood delivery time from four hours to an average of about 30 minutes.
And in “Swiss Post Medical Drone Carrying Clinical Laboratory Specimens Crashes in Switzerland,” we reported that the medical drone revolution experienced a setback when drone-pioneer Swiss Post (Switzerland’s postal service) saw one of its American-made Matternet drones crash into Lake Zurich, Switzerland. According to a Swiss Post news release, the drone went down carrying a “non-vital” blood sample (one that had been previously analyzed). The flight was part of a recently launched pilot program transporting blood samples between Zurich’s central laboratory and the Hirslanden Klinik Im Park, a private clinic on the opposite side of Lake Zurich.
Although not all drone delivery flights end in success, these projects clearly demonstrate how safe and reliable drone delivery of medical supplies and clinical laboratory specimens could one day be beneficial to medical communities.
Such drone deliveries will likely help medical professionals expedite diagnoses and treatment options for patients, especially in remote areas where land transportation would be much less timely.
Drone delivery of goods, including medical laboratory specimens, gains popularity around the world and FAA licensing in the US
In April, Dark Daily’s sister publication The Dark Report was first to report WakeMed Health and Hospitals’ use of a quadcopter drone to deliver patients’ medical laboratory specimens. The drone flew roundtrip between a complex of physicians’ offices on WakeMed’s Raleigh, N.C. campus and the central clinical laboratory.
The April flight was the first time a drone transport of medical
laboratory specimens in the US generated revenue.
Google Drone Delivery?
Not to be outdone, Alphabet (NASDAQ:GOOG), Google’s parent company, appears to be getting in on the trend. In April, the FAA issued an Air Carrier Certification to Wing Aviation LLC, an air delivery developer and subsidiary of Alphabet. Wing has recently launched a drone delivery service in Canberra, Australia and is testing a similar drone delivery service in the US.
“Our service allows customers to order a range of items such as fresh food, hot coffee, or over-the-counter chemist items on our mobile app, and have them delivered directly to their homes by drone in minutes,” Wing stated in a press release.

The FAA’s Air Carrier Certification allows Wing to deliver
goods from local businesses to private homes in the US. Their vertical take-off
drones weigh about 11 pounds, are equipped with a hover propeller to reduce
noise, and have wings that allow the devices to fly further and faster while using
less energy.
The FAA certification restricts drone deliveries to daylight
hours only with no flying in the rain. The devices are allowed to fly over
people but cannot hover above them, nor can they carry any hazardous
materials.
The company plans to launch a trial delivery service later
this year in the Blacksburg and Christiansburg areas of Southwest Virginia.
Wing hopes to add other markets to its drone delivery service in the
future.
“This is an important step forward for the safe testing and integration of drones into our economy. Safety continues to be our number one priority as this technology continues to develop and realize its full potential,” said U.S. Secretary of Transportation, Elaine L. Chao, in a press release.
Wing Drones Deliver Over Australia Too!
Wing has been testing its drone delivery service in
Australia since 2014. Over the past 18 months, Wing has flown over 70,000 test
flights and made more than 3,000 successful deliveries—including food, small
household items, and over-the-counter drug store items—as part of the Australia
project.
Unmanned aerial vehicles (UAVs, but commonly called drones) continue to gain in popularity around the world. As more drones appear in the sky, more practical functions are being discovered for them, including medical uses.
According to an article penned by Jeremy Tucker, DO, for Drones in Healthcare, numerous potential medical uses exist for drones. In addition to transport and delivery services, they may also be helpful in search and rescue missions and providing medical care and telemedicine services. Tucker is Executive Director for Patient Safety Solutions at US Acute Care Solutions.
“Drones are going to decrease the reliance on human beings
that provide care and decrease the cost of assisting people,” he predicted.
“Being able to cross long distances at faster speeds to deliver blood products
and lab samples also is a huge benefit. Now transporting blood products between
hospitals, for example, involves vehicles on the ground that are prone to
accidents and delays. Drones can help decrease those incidents.”
Prior to using drones for clinical laboratory specimen
deliveries, WakeMed relied on courier cars and trucks to transport specimens
within the campus. The ground delivery service could take up to an hour to
complete. By comparison, drones can make the same delivery in minutes, ensuring
lab specimens remain viable, and getting test results to patients faster.
Drone Delivery Around the World!
Dark Daily previously covered the use of drones to deliver laboratory specimens in Switzerland and laboratory supplies and blood products in Rwanda. And in 2017, Dark Daily reported that a team of researchers from Johns Hopkins University had successfully flown a drone carrying lab specimens more than 161 miles across the Arizona desert.
Might we soon see a Google drone delivery service for
clinical laboratory specimens as well?
The utilization of drones represents another market trend
that is creating opportunities for clinical laboratories. Using drones to
transport lab specimens could be a potential source of revenue and presents
labs with a pathway for providing value-added, timely service to healthcare
networks.
Demonstration project to move lab specimens by drone was successfully conducted in this alpine nation by Swiss Post and an eight-hospital health system
Delivering clinical laboratory specimens from point A to point B while maintaining the quality and integrity of critical samples is an ongoing issue for medical laboratories and pathology groups worldwide. This is especially true in countries prone to long winters and large amounts of snow. Ground transportation in those areas often experience delays, which can prevent hospitals from receiving needed test results and progressing with treatments that could save lives.
Switzerland is now taking the lead in using drones to transport medical laboratory specimens. In what is believed to be a global first, Ticino EOC, an eight-hospital medical group in Lugano, Switzerland, partnered with Swiss Post (Switzerland’s postal service) and transportation technology manufacturer Matternet of Menlo Park, Calif., to successfully transported laboratory samples between two of Ticino EOC’s hospitals by air using unmanned aerial vehicles (UAVs), commonly called drones. The samples arrived in good conditions after sailing high above blocked roadways. This demonstration project showed that drones can be used to safely deliver much needed lab specimens in both urban and remote rural medical settings.
Drones Present Opportunities for Medical Providers
The Ticino EOC group consists of eight hospital locations:
Lugano Regional Hospital;
Three locations of the Regional Hospital of Bellinzona and Valli (Bellinzona, Faido and Acquarossa);
Mendrisio Regional Hospital;
Locarno Regional Hospital;
Novation Rehabilitation Clinic; and
Oncological Institute of Italian Switzerland.
Matternet’s M2 drone is a quadcopter that travels up to 12 miles on a single battery charge. At just over 2.5 feet in diameter, the M2 can transport parcels up to 4.4 pounds. It cruises at about 22 miles/hour at an altitude of approximately164 to 328 feet above the ground.
According to Matternet’s website, the M2 is “engineered with encrypted communications, a parachute, precision landing, and a host of other safety features” and is “designed to be safe around people and infrastructure.”
Matternet received certification from the Swiss Federal Office for Civil Aviation (FOCA) to fly the drones at any time of the day. FOCA, along with Swiss Post, handle any regulatory issues involved in transporting human blood tissue and other medical laboratory specimens by drone and over public spaces.
“This is a big milestone for us. It means we can operate our technology throughout Switzerland. This will open a big opportunity in medical and e-commerce,” stated Andreas Raptopoulos, Matternet’s cofounder and CEO, in a TechCrunch article.

An additional safety certification is still needed before Swiss Post adds medical drone deliveries to their official services. The packaging that will contain blood samples or any other biohazard materials still requires approval. Swiss Post hopes to be using the drone service regularly for the transportation of lab samples by 2018.
Each drone can be launched using a smartphone application. The launching and landing sites transmit an infrared signal that the drone homes in on. It then delivers the specimens to their predetermined destinations. In the event of an in-flight failure, the drone discharges a parachute and lands.
Delivery by UAV Not New to Healthcare
This is not the first venture to use drones in the field of healthcare. Zipline, a logistics company based in Silicon Valley, is working with the Rwandan government to deliver blood supplies to rural clinics by drone. The company’s website states that, as of May 2017, they have completed over 350 deliveries of blood products to hospitals in Rwanda.
An article appearing in the scientific journal PLOS ONE, highlighted how important drones can be in serving people in rural and economically impoverished areas. Drones can provide healthcare workers with fast access to lab specimens for diagnosis and treatment in areas where roads are impassable or do not exist.
Researchers for that study proved that the movement of the drones does not have any effect on blood samples, which is a crucial element in transporting medical laboratory specimens.
“Such movements could have destroyed blood cells or prompted blood to coagulate and I thought all kinds of blood tests might be affected. But our study shows they weren’t, so that was cool,” Amukele stated.
Pathologist Timothy Amukele, MD, PhD (above left), teamed with engineers at Johns Hopkins to develop a drone courier system capable of transporting blood to clinical laboratories. (Photo copyright: Johns Hopkins Medicine.)
For the study, Amukele and his team collected blood samples from 56 healthy volunteers and drove the samples to a drone launching field. Half of the samples were then driven to a clinical laboratory for processing and the other half were placed on the drones for flights lasting from six to 38 minutes.
Comparison of Clinical Lab Specimens Transported by Ground and by Drone
Both the flown and the non-flown samples underwent 33 common medical laboratory tests. The test results showed almost no difference between the two groups of samples. A test for carbon dioxide was the only one that generated different results, but the team did not know if that was due to the movement of the drones or the fact that the samples sat for up to eight hours before being tested.
Amukele is taking part in a collaboration between Johns Hopkins and Makerere University in Uganda. He noted that they would like to perform a study in a more remote location, possibly in Africa, where clinical laboratories can sometimes be more than 60-miles from clinics.
“A drone could go 100 km [approximately 62 miles] in 40 minutes,” noted Amukele in the Johns Hopkins news release. “They’re less expensive than motorcycles, are not subject to traffic delays, and the technology already exists for the drone to be programmed to ‘home’ to certain GPS coordinates, like a carrier pigeon.”
Opportunities for Clinical Laboratories
Use of drones is subject to each country’s laws and regulations. In the US, drone use is regulated by guidelines established by the Federal Aviation Administration (FAA). In some cases, the drone must be registered with the FAA and the operator must have a remote pilot certificate to legally fly a drone.
These projects highlight the critical need for cost-effective, safe, dependable transportation of biological materials in a timely manner. For pathologists and clinical laboratories, drones could prove to be another opportunity to provide high-quality, value- added services to healthcare consumers and other medical professionals.
