About this Test

What is the COVID-19 real time RT- PCR, DNA swab test?

The COVID-19 swab test is for the qualitative detection of nucleic acid from SARS-CoV-2 in upper and lower respiratory specimens. .

Results are for the identification of SARS-CoV-2 RNA. The SARS-CoV-2 RNA is generally detectable in respiratory specimens during the acute phase of infection. Positive results are indicative of the presence of SARS-CoV-2 RNA; clinical correlation with patient history and other diagnostic information is necessary to determine patient infection status. Positive results do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of disease. Laboratories within the United States and its territories are required to report all positive results to the appropriate public health authorities. The COVID-19 RT-PCR is only for use under the Food and Drug Administration’s Emergency Use Authorization.

How is the Antibodies (Blood) test different from the Rt-qPCR,DNA (Swab) test?

The RT-PCR,DNA test determines if the individual is infected with SARS-CoV-2 and considered to be able to transmit the disease (a positive test) or is negative for the virus. This test cannot tell whether a person is immune from past infection or has yet to be exposed and is still in danger.

The IgG & IgM antibodies test is based on the quantitative detection of IgM and IgG that are specifically generated by the body in response to SARS-CoV-2 infection. This can be used to determine recent & past exposure.

Researchers said having the IgG antibodies gives you protection from the virus -- but it doesn’t mean you’re immune for the rest of your life. You could get sick again. Still, they’re calling the test a milestone towards getting life back to normal.

Clinical Significance of Utilizing the DNA (swab) test along with the Antibodies (blood) test.

Antibody tests for COVID-19 cannot confirm the presence of the virus in your system at the present day. It can only tell whether you have been exposed in the past or if you have never been exposed to SARS-CoV-2. Consequently, it should only be used alone as a screening test and should be used in tandem with a genetic-based test to determine a complete status.
