In addition to the highly contagious nature of the virus, another scary aspect is the inaccuracies of theCOVID-19 test which result in false negatives. A false negative is not only worrying for the patient, but he/she can also turn into a silent carrier of the novel coronavirus, without accurate results. A false negative is when the virus does not show up in the tests even though the person has contracted the infection.

As of now, there are two main types of tests for detecting COVID 19 ie. RT-PCR test and antibody tests, out of which the reverse-transcription polymerase chain reaction test are excellent in ideal conditions. The RT-PCR test is a molecular test for which swabs are taken from the far back of the nose and mouth, while the antibody test is done by collecting blood samples.
