In mid-March, Iwen put his idea to the test. He ran a few tests, each time taking a sample from a patient with confirmed COVID-19 who had very low levels of virus in the sample, and adding it to four other samples that were negative for COVID-19. He used the U.S. Centers for Disease Control’s (CDC) COVID-19 test, and despite the low levels of virus, each time, he was able to pick up the positive sample.

He presented his data to the CDC and the Food and Drug Administration, which must validate and approve any diagnostic test that produces results returned to patients.
