In June 1981, the rapid-response newsletter of the Center for Disease Control, the Mortality and Morbidity Weekly Report, published news of an unusual pneumonia in otherwise healthy young men in Los Angeles. It would take four years from those first recorded cases of AIDS to the first FDA-approved test for HIV, and over a decade before the first rapid test. And so, if just a year ago, any of my colleagues had told me that we could have a point-of-care rapid test after mere months of a new pathogen’s emergence, I would have regarded it as hopelessly optimistic.
Yet that is what the first-of-its-kind alliance between the U.S. biotechnology industry and the federal government has delivered. Just four months after the emergence of Covid-19, a dizzying array of tests is available to patients, physicians, and researchers. The initial tests, dependent on identifying the viral genome, have now been supplanted by much faster, much less expensive antibody tests. Unlike genomic tests, which require laboratory equipment and take several hours to complete, the new antibody-based tests are portable, and some don’t require any special materials other than saline. The antibody tests may answer questions not only about a patient’s current state but also about whether he has been exposed in the past by measuring antibodies that the immune system creates in response to the coronavirus. Finally, just today, the FDA announced that it is granting authorization for the first Covid-19 test that can be taken at home, affording an opportunity for many people in at-risk groups who have forgone testing up to now. By all measures, the emergency regime set up by the FDA has opened the floodgates of innovation on one of the most vexing problems of responding to a viral outbreak, and with great success.
