Step-by-step Process of PCR test

The PCR test includes three basic steps explained below.

Collecting the specimen

Specimen collection is the first and easy step where a health professional uses a swab (a soft piece of material on a stick or rod) to collect respiratory material present in your nose. The swab can be of several different types. It can be a nasal swab that immediately collects a specimen from your nostrils or a nasopharyngeal swab inserted into your nasal cavity to collect the sample. Once the sample is collected, the swab is put and sealed in a tube and moved to the laboratory for further inspection.
Extraction of genetic material
When the sample is received by a healthcare professional at the laboratory, they separate (extracts) the genetic material of the specimen from the other contents of the material.

PCR
This final step of the process involves the amplification of genetic material within the test tube. It is done with the help of several special chemicals, enzymes, and the thermal cycler (a PCR machine). After a number of heating and cooling cycles, the test tube shows millions of copies of the genetic material of the SARS-CoV-2 virus. Now, suppose the SARS-CoV-2 is really present in the genetic material. In that case, it gets detected easily with the help of a chemical that produces a fluorescent light on sensing it in the sample. There are certain indicators that prove the signal is a positive test result sign.

The PCR test is considered highly reliable and accurate for detecting active infection of the SARS-CoV-2 virus. Although most of these tests take hours to be done, some of them are faster too.

Steps of RT-PCR Technique : MED NOW LABS

  Steps of RT-PCR Technique As mentioned above, the RT-PCR process is only a little different from that of PCR. Apart from the one addition of reverse transcription in RT-PCR, both techniques are almost the same. So, let’s start the RT-PCR technique from its reverse transcription stage. Reverse Transcription A reverse transcriptase enzyme is used to synthesize a cDNA (complementary DNA) strand with nucleotides, and its end product turns out to be mRNA (cDNA hybrid). This process takes place between 40 to 50 degrees Celsius; it usually varies with the properties of the reverse transcriptase enzyme being used. Once the reverse transcription is done, the mRNAs are hydrolyzed, and during a first temperature cycle, the cDNAs are replicated by DNA polymerase. Denaturation Here, the combination of components left is heated to a temperature of 94 degrees Celsius for less than half a minute. Along with the denaturation of double-stranded cDNA into single strands, the hydrogen bonds are also...
