We've all been introduced to a variety of new phrases since the start of the COVID-19 epidemic, one of which is "PCR testing." What precisely is a PCR test, and how accurate is this type of testing? Here is the answer you are looking for.

What Exactly Is PCR Testing?

Before digging into the accuracy of PCR test and rapid test, it may be beneficial to define PCR tests. A nasopharyngeal swab is used in a polymerase chain reaction (PCR) test to detect for the genetic material of the virus that causes COVID-19 (SARS-CoV-2). This is not the same as fast antigen testing, which uses a nasopharyngeal swab but looks for protein fragments unique to the COVID-19 virus.

How does the test function?

A PCR test is used to amplify DNA sequences. To help replicate these sequences, it uses DNA primers, DNA bases, enzymes, a buffer solution, and heat cycling.

The first step is to acquire a sample from the test subject. The sample kinds that are acceptable are described below.

The sample is then heated by a laboratory researcher using a specialized equipment. This divides the DNA within into two single-stranded bits. The reaction is then allowed to cool so that primers may connect to the template DNA strands. It then warms up again to allow the Taq polymerase enzyme to add DNA bases to the templates. The original DNA sample is duplicated, resulting in two strands.

Time taken to get result

A PCR test can produce findings in as little as a few minutes or as long as several days. The findings of an onsite analyzer are immediate. Due to processing delays, it may take longer for findings to be returned when doctors submit samples to an off-site lab. PCR tests appear to be reliable in detecting the presence of SARS-CoV-2.
