New advancements in mHealth, though encroaching on testing traditionally performed at clinical laboratories, offer opportunity to expand testing to remote locations
Mobile technology continues to impact clinical laboratories and anatomic pathology groups and is a major driver in precision medicine, as Dark Daily has reported. Most of the mobile-test development which incorporates smartphones as the testing device, however, has been for chemistry and immunoassay types of lab tests. Now, a new developer in Monmouth Junction, NJ, has created a Complete Blood Count (CBC) test that runs on devices attached to smartphones.
Such devices enable doctors to order test panels for patients in remote locations that also may lack resources, such as electricity.
The developer is Essenlix and it calls its new testing device iMOST (instant Mobile Self-Testing). According to the company’s website, which is mostly “Under Construction,” iMOST can provide “accurate blood and other healthcare testing in less than 60 seconds by a smartphone and matchbox-size-attachment, anywhere, anytime, and affordable to everyone.”
The company description on the Longitude Prize website states that Essenlix “uses multidisciplinary approaches to develop a new innovative platform of simple, fast, ultrasensitive, bio/chemical sensing and imaging for life science, diagnostics, and personal health.
The Longitude Prize competition was established to promote the invention of “an affordable, accurate, fast and easy-to-use test for bacterial infections that will allow health professionals worldwide to administer the right antibiotics at the right time,” the website states.
Essenlix’s iMOST mobile testing system consists of:
- a mobile application (app);
- the device attachment, which goes over the phone’s camera; and,
- a cartridge that holds a sample of blood.
So far, there have been two trials with a total of 92 participants, comparing traditional CBC testing with the Essenlix test. The results were within the FDA’s requirements for allowable error, prompting Chou to tell Business Insider, “Our error is clearly smaller than the FDA’s requirement, so the data is very, very good.”
Chou and his team are working toward FDA approval.
Other Testing Devices That Attached to Smartphones
Aydogan Ozcan, PhD, Professor of Electrical Engineering and Bioengineering at UCLA, and Mats Nilsson, PhD, Professor and Scientific Director of the Science for Life Laboratory at Stockholm University, have developed an attachment that they say can transform “a phone into a biomolecular analysis and diagnostics microscope,” according to The Pathologist. Dark Daily has published many e-briefings on Ozcan’s innovations over the years.
Their goal, the researchers said, was to create technology that can be used in low- and middle-income areas (LMICs), as well as in more advanced locations, such as Sweden. “I’ve been involved in other projects where we’ve looked at point-of-care diagnostic approaches,” he said, “and it seems to be very important that the devices [do not] rely on wired electricity or networks to serve not only LMICs, but also modern, developed environments. It’s often difficult to find an available power socket in Swedish hospitals.”
The molecular diagnostic tests that can be done with smartphone attachments—such as those developed by Ozcan and Nilsson—represent another way of using a smartphone in the healthcare arena, The Pathologist points out. Their invention combines the smartphone’s native camera, an app, optomechanical lasers, and an algorithm contained within the attachment to carry out fluorescence microscopy in the field.
Future of Mobile-Testing
An article appearing in the Financial Times describes some of the ways mobile technology is changing healthcare, including diagnostics that have traditionally been performed in the medical pathology laboratories.
“Doctors scan your body to look for irregularities, but they rely on pathologists in the lab to accurately diagnose any infection,” the article notes. “There, body fluids such as blood, urine, or spit are tested for lurking microbes or unexpected metabolites or chemicals wreaking havoc in your body. Now companies are miniaturizing these tests to create mobile pathology labs.”
Apple introduced the first iPhone in 2007. It’s doubtful anyone imagined the innovations in diagnostics and pathology that would soon follow. Thus, trying to predict what may be coming in coming decades—or even next year—would be futile. However, scientists and researchers themselves are indicating the direction development is headed.
Should Essenlix and other mobile-lab-test developers succeed in their efforts, it would represent yet another tectonic shift for medical pathology laboratories. Clinical laboratory managers and stakeholders should be ready, for the words of the ancient Greek philosopher Heraclitus have never been truer: “Change is the only constant in life.”
