HOUSTON – The Food and Drug Administration is warning about the risk of false results, specifically false negatives, with Curative’s COVID-19 test. The agency posted an alert to patients and healthcare providers on its website on Monday. According to Curative’s website, the test involves coughing three to five times and then swabbing the inside of your mouth. The FDA said the test needs to be done properly, under the watch of a trained healthcare worker, to reduce the risk of the wrong result. The FDA’s post said healthcare providers should consider retesting patients with a different test if they suspect the result was not accurate and the result was given recently.
