New Blood Test Can Reveal Past Viruses
Washington (ArabNews) – A new and inexpensive test is making it possible to identify all of a person’s past and present viral infections by simply analyzing a drop of blood.
The method, called VirScan, provides an alternative to sampling blood for one virus at a time, said researchers, who described the new technology in the US journal Science Thursday.
The new approach, developed by scientists from the Howard Hughes Medical Institute (HHMI), helps health professionals identify multiple factors that might be affecting a person’s health, rather than just one virus.
It also helps researchers analyze viruses in a larger population, and can be performed at $25 per blood sample.
