A Double-Barreled Approach To Antibody Testing Could Improve Accuracy
NPRA Double-Barreled Approach To Antibody Testing Could Improve Accuracy Enlarge this image toggle caption Joe Raedle/Getty Images Joe Raedle/Getty Images Last month the White House issued guidelines suggesting a way to reduce the number of false positive results in antibody tests: Run two tests. Dr. Alex Marson at UCSF says they may be able to take the data they've already gathered and reanalyze it quickly, to see if different tests produce a different pattern of false positives, as would be needed for the two-test strategy. Sponsor Message He's also thinking about broader questions, such as when it would make sense to spend the money on two tests, as opposed to running a single slower but highly accurate test in a lab. Marson says, depending on the circumstances, it might make sense to run one of these highly accurate tests than running two with lower performance – or perhaps using the disposable test to screen a poplulation and then follow up with the ELISA.
