What You Need To Know About The COVID-19 PCR Test
Since the outbreak of the deadly pandemic in 2020, the importance of reliable and accessible methods of testing for the COVID-19 disease has become so apparent.
You’ve probably heard of the term ‘PCR Test’ before and may be wondering what it means and how it relates to COVID 19.
PCR stands for Polymerase Chain Reaction. It is a special test that helps detect genetic material from a particular organism, for example, a virus.
How does the PCR test work?
The PCR test does the work of spotting the COVID-19 virus if it is present during the period of testing. The test also can detect fragments or pieces of the virus, even after it is no longer in effect.
The PCR test for COVID-19 operates by analyzing the upper respiratory specimen in search of the genetic material (Ribonucleic acid) of the COVID virus. The technology amplifies small portions of the material gotten via test specimens into detectable forms. Hence, a positive PCR test implies that you likely have COVID-19, whereas a negative PCR test implies you probably did not have COVID-19 at the time of testing.
What are the steps in COVID-19 PCR testing?
There are three major steps in PCR testing.
- The Sample Collection: Our healthcare provider uses a swap (a soft tip on a long, usually flexible stick) to collect respiratory material in the nose. The swaps come in two types: nasal swabs and the nasopharyngeal swab. The nasal swap collects test samples immediately inside the nostrils, while the nasopharyngeal swab can go further into the nasal cavity.
- The Extraction: During this process, the collected sample is closely examined, as genetic material is isolated from the remaining material in the COVID-19 test sample.
- The PCR: This step employs unique chemicals and enzymes, and a particular machine is known as the thermal cycler. Within the machine, there are heating and cooling processes that help amplify the quantity of target genetic material in the test tube. The PCR machine can spot the virus once the genetic material collected during testing has been amplified enough.
Who Should Get COVID-19 PCR Test?
It is recommended that you get tested if you have symptoms such as fever, cough, fatigue, muscle ache, shortness of breath, headache, sore throat, nausea, diarrhea, loss of taste or smell.
You should note that not every person with COVID-19 will develop symptoms. A special grade of persons, referred to as asymptomatic people, may not display all or any the signs of COVID-19 but still, they are able to spread the virus and even suffer the effects of the virus at its full-blown stage.
As a safety measure to protect the citizens of any country (including your home country) it is required you get the COVID-19 PCR test while traveling out of or back into the country. This goes to say that if you are a frequent traveler, it is important to have your test done as frequent as you travel to help curb the spread of the virus across borders
Even if you have been vaccinated previously, you need to still check in and get tested if you feel the symptoms closely related to Covid-19.
