Testing for COVID-19 has ramped up in recent months. While initially, tests were hard to come by, today most Maryland pharmacies are conducting tests, making them widely available. However, the surge in testing has resulted in a corresponding increase in the number of experts who are concerned that tests are providing people with false-negative results. Given the highly contagious nature of COVID-19, false negatives have the potential to cause a resurgence in the virus, putting everyone at risk.
According to a recent news report, 12 people who were tested at a Walgreen’s pharmacy were initially told that they were negative for COVID-19, only to learn later that was not the case. Evidently, the erroneous results came out of Delaware, where the local government had an agreement with Walgreen’s. In all, Walgreen’s collected over 2,900 samples at drive-up testing sites.
The tests appeared to be accurate, and the problem was not with the reliability of the test. In fact, the state Department of Health reviewed each of the Walgreen’s tests for accuracy and confirmed that “no patients who tested negative were given incorrect results.” However, 12 patients were called and told that they tested negative when, in fact, they had tested positive. The report notes that the error did not occur at the local Walgreen’s stores, implying that the lab may have been responsible for the errors.
