PCR Covid Test - what is it and how the test is done
With the pandemic caused by COVID-19 (Coronavirus), the spread of tests and swabs to detect infection from the virus has become the new normal.
The Covid PCR Test is a relatively quick test that allows you to confirm a person's positive or negative COVID-19 status and get the result in no time.
How reliable is a Covid PCR Test?
The PCR (Polymerase Chain Reaction) test for COVID-19 is a test that helps analyze whether or not a person suffers from Covid infection. The PCR test for Covid is considered the standard par excellence for the detection of Coronavirus.
The molecular swab is a very reliable test and has been commonly used worldwide from the beginning of the pandemic to today. The RT-PCR (Reverse Transcriptase Polymerase Chain Reaction) antigen test is the standard, rapid and accurate method for identifying any traces of current Coronavirus infection in the body.
Covid PCR Test: How Does It Work?
The Covid PCR Swab is a molecular test that works on the principle of detecting the RNA that causes Coronavirus infection.
The Covid PCR Test requires a swab that can be self-administered or performed by a healthcare professional. It is done by taking a nasopharyngeal swab inserted deep into the nasal cavity to collect the sample. After a patient sample is collected, the molecular swab is sent to a specialized laboratory which can often return the result in about 24 hours. The sample collected from the swab is then manipulated to extract its genetic material.
When you should take a Covid PCR Test
Your family doctor, or a doctor if you are away from home, may advise you to take a PCR swab if they deem it necessary based on the symptoms presented.
It is usually recommended that a person take a Covid PCR Test if they have developed one or more suspicious symptoms such as fever, cough, congestion, shortness of breath, muscle aches, loss of taste or smell, diarrhoea, nausea, or vomiting.
