Coronavirus has become a major concern around the world. Accurate testing is one way to help stay protected against this potentially serious virus The most accurate diagnostic test used for the diagnosis of COVID-19 is the COVID PCR test.

What is PCR COVID testing?

Polymerase chain reaction, or PCR, is a molecular test used for the diagnosis of COVID-19 infections. It comes under the category of diagnostic tests, and it’s performed to check whether a person is infected with the SARS-CoV-2 virus.

In this type of test, a sample is obtained from a person’s nose. The sample is replicated multiple times so that a detectable amount of virus, if present, is gathered. This test is considered to be very accurate and reliable.

Purpose

The test is primarily used to check for active coronavirus infections.

This test is used to screen individuals to decide whether they need to self-isolate or not. This test may be used to direct treatment decisions, although it cannot independently determine the severity of infection.

Procedure

The procedure for PCR COVID testing starts with obtaining a specimen from the patient’s nose using a nasal swab.

Once the sample is obtained, it is then sent to an outside lab, where those specimens are fed to a PCR machine. This machine can generate millions of copies of that specimen within a very short duration of time. If the specimen contains specific viral genome sequences, it interprets the results as positive. The results of this test are further explained below.

Results

If antigens to the COVID-19 virus are detected in the specimen, the result will be interpreted as positive. COVID-19 testing can be positive even if a patient is asymptomatic.

PCR testing can produce false-positive results due to the presence of some other viruses in the specimen. In that case, the results are referred to as false positives. These cases are extremely rare. PCR testing is considered the “gold standard” of COVID-19 testing.
