Text-Only NPR.org : Scientists Warn CDC Testing Data Could Create Misleading Picture Of Pandemic

In addition, combining antibody testing with diagnostic testing could reduce the number of tests that appear to be producing positive results, lowering the overall "positivity rate." That's another important benchmark. The World Health Organization has recommended a positivity rate of 10% or less as a signal of whether enough testing is taking place.

"I suspect it will artificially lower the percent positive," wrote Caitlin Rivers, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health, in another email to NPR about the CDC testing data.
