Run a single test to determine which viruses have infected an individual

Run a single test to determine which viruses have infected an individual | healthcare technology | Scoop.it

New technology developed by Howard Hughes Medical Institute (HHMI) researchers makes it possible to test for current and past infections with any known human virus by analyzing a single drop of a person's blood. The method, called VirScan, is an efficient alternative to existing diagnostics that test for specific viruses one at a time, according to the scientists.


With VirScan, researchers can run a single test to determine which viruses have infected an individual, rather than limiting their analysis to particular viruses.


That unbiased approach could uncover unexpected factors affecting individual patients' health, and also expands opportunities to analyze and compare viral infections in large populations. The analysis reportedly can be performed for about $25 per blood sample.

“We've developed a screening methodology to basically look back in time in people's sera and see what viruses they have experienced,” says Stephen J. Elledge, an HHMI investigator at Brigham and Women's Hospital who led an international team that developed VirScan. “Instead of testing for one individual virus at a time, which is labor intensive, we can assay all of these at once. It's one-stop shopping.”

VirScan works by screening the blood for antibodies against any of the 206 species of viruses known to infect humans. The immune system produces pathogen-specific antibodies when it encounters a virus for the first time, and it can continue to make those antibodies for years or decades after it clears an infection. That means VirScan not only identifies viral infections that the immune system is actively fighting, but also provides a history of an individual's past infections.

Intermountain researchers develop smartphone-based lab test for stress

Intermountain researchers develop smartphone-based lab test for stress | healthcare technology | Scoop.it

Researchers from Intermountain Healthcare have developed a smartphone-based test for measuring salivary cortisol, which can help care providers understand the patient’s stress levels. The test can be performed at the point of care in just five minutes.


When someone feels stress, their body’s natural response is to release hormones, including adrenaline and cortisol, to help them deal with the “threat”. When cortisol is released, it increases glucose in the system, but also curbs nonessential functions including the digestive system, the reproductive system and growth processes.


When people feel stress throughout the day, thus releasing too much cortisol, it can lead to anxiety, depression, digestive problems, heart disease, sleep problems, weight gain, and memory and concentration impairment.


To perform the test, care providers use a smartphone’s camera to take a picture using the flash. From there, the image analysis app can identify the user’s cortisol levels. 


“When cortisol levels are overlooked too many people suffer and die because of excess or insufficient cortisol,” lead researcher and Intermountain Medical Center Director of Diabetes and Endocrinology Dr. Joel Ehrenkranz said in a statement.


Ehrenkranz also believes this test will be especially helpful for people with diabetes.
