What is the COVID PCR test?
A COVID PCR test (Polymerase Chain Reaction test) is a molecular gene amplification test done to determine the presence of the SARS-CoV-2 virus which causes COVID-19. It functions by determining the genetic material of the virus from a sample, which is usually a nasal or throat swab. The PCR method is the most commonly used method for COVID-19 testing due to its high sensitivity and accuracy. The test uses the virus’ genetic material to confirm the presence of the virus, even if it is present in small quantities, and is considered very reliable in confirming an acute viral infection.
The COVID PCR test can give the infection in the early stages, even before the patient has symptoms, and is very useful for identifying asymptomatic cases of the disease that can spread the virus unnoticed.
How is the Test Performed?
The COVID PCR test requires swabbing the patient’s nose or throat and the sample is then transported to a laboratory for testing. This process involves inserting a long cotton-tipped swab into the nostrils or throat to pick cells and mucus that may contain viral materials. The sample is then processed using a polymerase chain reaction (PCR) machine to amplify any viral genetic material that may be present in the sample.
While getting the sample may be a bit uncomfortable, it is not too painful and is mostly just a quick process. PCR testing is the most accurate form of the test, and the results are usually ready in a few hours to a few days depending on the laboratory.
What are the symptoms that prompt this test?
The common symptoms associated with the COVID-19 infection are mentioned below;
General Symptoms
- Fever followed by chills
- Cough
- Breathing difficulty
- Tiredness
- Body or muscle pain
- Inability to taste or smell
- Sore throat
- Runny nose
- Vomiting
- Diarrhea
What are the Normal Ranges for This Test?
The COVID PCR test is qualitative and the results are reported as negative or positive. A negative test is an indication that the SARS-COV2 virus is not present in an individual whereas a positive result is an indication of the presence of the virus and the infected individuals should isolate themselves from society to limit the spread of the virus.
**A false negative test can occur due to the improper collection of the sample or if the person had an early stage of the test. **

What Happens if Test Results Show Abnormal Levels?
If a positive result is obtained, it means the person is infected with the SARS-CoV-2 virus and should adhere to the advised health measures, including quarantining, informing the people he or she has had contact with, and seeking medical checkups if need be. Other exams, such as a computed tomography (CT) scan or x-ray of the chest, may be required if the patient’s symptoms are severe.
However, it is important that people who are negative should also carry on with preventive measures like mask-wearing, washing hands, and avoiding close contact with people as no test is 100% accurate.
It also means that repeat testing may be considered for patients with symptoms but negative PCR results since the viral load is dynamically changing during the first stages of the disease.
