    False positives in most manufacturers tests are quite large relative the the seroprevalence we’re trying to measure at the moment.

    Other scientists were less sanguine than Dr. Marson. Four of the tests produced false-positive rates ranging from 11 percent to 16 percent; many of the rest hovered around 5 percent.
    “Those numbers are just unacceptable,” said Scott Hensley, a microbiologist at the University of Pennsylvania. “The tone of the paper is, ‘Look how good the tests are.’ But I look at these data, and I don’t really see that.”

      That is way, way too high for any sort of reliability.

        Well, these will get better over time one presumes and also the error rates will matter less as we have greater and greater percentages infected.

        So over time it will give us a good understanding. Probably not so much in April or May.
