Sound Wave Acoustic Tweezers Locate and Isolate Circulating Tumor Cells in Liquid Biopsies; Could Lead to Less Invasive Cancer Diagnostics and Treatments

Pathologists will be interested to learn that this latest version of the acoustic tweezer device requires about five hours to identify the CTCs in a sample of blood

Medical laboratory leaders and pathologists are well aware that circulating tumor cells (CTCs) released by primary tumors into the bloodstream are fragile and easily damaged. Many studies have sought to find ways to separate CTCs from surrounding cells. Such a process could then be used as an early-detection biomarker to detect cancer from a sample of blood.

One team of researchers believe it has a way to accomplish this. These researchers are using sound waves to gently detect and isolate CTCs in blood samples. In turn, this could make it possible to diagnose cancer using “liquid biopsies” as opposed to invasive conventional biopsies.

Researchers from Carnegie Mellon University (CMU) in collaboration with researchers from the Massachusetts Institute of Technology (MIT) and Pennsylvania State University (Penn State) have developed a method for using acoustic tweezers and sound waves to separate blood-borne cancer cells from white blood cells. The research team believes this new device could one day replace invasive biopsies, according to a CMU article. (more…)

Researchers at Howard Hughes Medical Institute Develop Blood Test That Reveals a Patient’s Viral History; Could Reduce Unnecessary Clinical Laboratory Testing

The VirScan test gives doctors insight into a patient’s lifetime exposure to viruses and thus may be developed into a useful medical laboratory test

Scientists and pathologists are learning that blood is like a time capsule, holding precious information about exposure to viruses over the years—chickenpox at five, mononucleosis at 18, flu at 40. You get the idea.

Now, researchers at Howard Hughes Medical Institute (HHMI)  have found a way to tap that entire data stream, so to speak. An inexpensive blood test, they say, reveals every virus that has passed through the body over time.

New Discoveries Could Lead to a Useful Clinical Laboratory Test

The testing method, called VirScan by researchers, is an efficient alternative to current medical laboratory tests that test for specific viruses one at a time, according to an HHMI news statement about the new technology. (more…)

Smartphone “Dongle” Achieves Capabilities of Big Clinical Laboratory Analyzers: Diagnoses Three Diseases at Once from Single Drop of Blood

This breakthrough in technology miniaturization holds great promise for improving public health, but portends a disruptive future ahead for the medical labs 

Is the medical laboratory industry ready for a handheld device that can do immunoassay testing without requiring any stored energy? The secret of this device, already undergoing field trials in Rwanda, is that it uses a smartphone accessory, or “dongle,” to capture and transmit the results of the lab tests.

This innovative smartphone device accurately diagnoses HIV and syphilis with a finger prick of blood and displays the results on the smartphone screen within 15 minutes, according to a Columbia Engineering News Service report.

An Ideal Device for Field Work in Resource Poor Areas

It’s mobile and inexpensive, making it an ideal diagnostic tool for use in poor, remote regions of the world. According to World Health Organization (WHO) statistics, the highest percentages of all sexually transmitted disease (STD) cases occur in developing and underdeveloped nations. (more…)

New Microfluidic Blood-draw Device Could Replace Needle Sticks and Venipunctures at Medical Laboratories

By placing this low-cost, disposable device developed at the University of Wisconsin-Madison on their arms or abdomens, patients can collect their own blood at home in minutes

For more than two years, the nation’s media have been captivated by Theranos CEO Elizabeth Holmes’ vision of offering patients who need blood tests a finger stick collection instead of a venipuncture. Meanwhile, in research labs across the nation, there are credible efforts to develop ways to collect medical laboratory test specimens that require no needles at all.

On such effort may soon enter the market. It is an innovative, needleless blood-collection device called HemoLink developed by a research team at the University of Wisconsin-Madison. Users simply place a device with the diameter of a golf ball against their arms or abdomens for two minutes. During that time, the device draws blood from capillaries into a small container. Patients would then mail the tube of collected blood to a medical laboratory for analysis.

This non-threatening device is ideal for children. However, patients who require recurrent blood tests to monitor health conditions would also benefit, as it would save them frequent trips to clinical laboratories for blood draws using traditional needle-stick methods. (more…)

UCSF Study Puts Spotlight on the High Prices of Medical Laboratory Tests Charged by California Hospitals

Researchers at the University of California San Francisco revealed that the cost for a simple cholesterol test ranged from as little as $10 to as much as $10,169!

Clinical laboratories owned by hospitals and health systems should take note of a public study of hospital laboratory test prices that was conducted by researchers at the University of California at San Francisco (UCSF). It was published this summer and showed a remarkable range of prices for medical laboratory tests charged by California hospitals.

How about a charge of $10,169 for a routine blood cholesterol test? This was one finding a study discussed in the August 2014 issue of the British Medical Journal Open blog. The study was led by Renee Hsia, M.D.. She is an associate professor of Emergency Medicine and Health Policy at the UCSF Medical School. Hsia and her colleagues compared charges for 10 common clinical laboratory tests that were reported in 2011 by all non-federal California hospitals. (more…)
