New Blood Test Can Detect Every Virus You’ve Ever Had
A new medical breakthrough may soon provide the clearest picture of your medical history yet. A simple blood test will be able to detect every virus you have ever had, giving you a more comprehensive picture of your overall health and giving medical professionals an important understanding of how viruses can spread.
A new experimental test called VirScan can detect the 206 virus species known to infect humans and more than 1,000 known virus strains just by testing a small amount of blood, according to the journal Science. Scientists tested VirScan on almost 600 people on four continents and detected an average of 10 strains per person, many of which were common like the cold or flu. But at least two people tested positive for 84 strains. The new blood test could help doctors trace how viruses spread, and scientists say they believe the test could be expanded as new ones are discovered.
