COVID-19 Testing Tips For The Most Accurate Results

Now having issued over 39 Million COVID-19 tests reported in the U.S. alone according to the Center for Disease Control and Prevention (CDC), new research is drawing attention to inaccuracies of results. With the majority of issued tests collecting a sample through swabbing the back of the nose or throat, researchers from Johns Hopkins University attribute as many as 1 in 5 false negative results to viral genetic differences and varying sample collection techniques.
False-negative results of COVID-19 have been a major contributor to the spread of the virus, with the World Health Organization (WHO) reporting 80% of infections are mild or asymptomatic. Timing of testing is also vital in gaining accurate results. One study found that testing too close to the onset of infection could fully miss a positive diagnosis, with results becoming more and more accurate throughout the incubation period, with the lowest probability of a false-negative 8 days after exposure and roughly 3 days after the onset of symptoms.
More frequent testing may be helpful in positive reporting of infection with so many asymptomatic carriers not knowing they are infected. At-home testing solutions, like the FDA authorized Kroger Health COVID-19 Test Home Collection Kit, offer the ability to self-administer a test, as well as a retest, under the supervision of a medical professional via telehealth.
Particularly as the world begins to reopen and return to a sense of new normalcy, it’s more important than ever to be cleared of infection before reintegrating or removing personal protective equipment (PPE).
