New technologies made it possible to check present and past infections by analyzing a single drop of blood of that person. The process, known as VirScan, can be an effective substitute for recent diagnostics in which check intended for specific viruses individually. With this test, scientists found that Virscan would be a single test to determine all the infections instead of limiting the analysis to particular viral infection.
This approach could cover unexpected factors affecting individual patients' health, and also expands opportunities to analyze and compare viral infections in large populations. This approach has developed is not limited to antiviral antibodies. But Elledge and his colleagues also using it to look for antibodies that attack a body's own tissue in certain autoimmune diseases that are associated with cancer.
A similar approach could also be used to screen for antibodies against other types of pathogens. Source: Howard Hughes Medical Institute (HHMI)
