All You Need to Know about PCR Testing

To diagnose the COVID-19, it is crucial to go for the PCR test. This procedure involves the nose swab PCR test for COVID-19 that helps to provide reliable test results. If the test is negative, it reveals that you may not have coronavirus but if the PCR test Pakistan is positive, it shows that you may have COVID-19. It is the test that is performed when an individual experiences some symptoms of the COVID-19 or is exposed to someone who tested positive.

Let’s begin our journey to explore what it is.

What is a PCR test?

PCR refers to the polymerase chain reaction test that is performed to detect genetic material from a specific organism. The specific organisms may be a virus that you can get exposed to. This test helps to check if there is a virus or its fragments. People often go for this test when the doctor suspects that they might have been exposed to the virus or have been experiencing some symptoms, like cough, loss of taste and smell, etc.

But people often ask:

What is different between the COVID-19 PCR test and the PCR test?

Now, we know what a PCR test but the COVID-19 PCR test is a molecular test that helps to check the upper respiratory specimen that detects the genetic material of SARS-CoV-2. This is the virus that causes COVID-19. This test is performed to amplify the RNA from specimens into deoxyribonucleic acid DNA. Experts claim that the PCR test is the best way to detect the virus of COVID-19 as it is more reliable as compared to other procedures.

Do you know?

Who are the eligible candidates for COVID-19?

COVID-19 is a global pandemic that has already targeted many of us and has been a leading death cause worldwide. But detection of the virus can help for early treatment before it affects the health. The healthcare provider can ask for a PCR test when you have been experiencing some symptoms, like:

  • Cough
  • Sore throat
  • Headache
  • Congestion
  • Diarrhea
  • Nausea
  • Vomiting
  • Fever or chills
  • Fatigue
  • Muscle or body aches
  • Shortness of breath
  • New loss of smell and taste

Many people who have been affected by the COVID-19 developed symptoms at first. If a person feels unwell during the pandemic, they should get medical help as soon as possible for a complete checkup. The healthcare provider will help you know about the details and how you can isolate yourself by following some instructions.

Other Details about the PCR Test – You Need to Know About 

If you are going for a PCR test, it is crucial to know about the steps of PCR and how it detects the virus.

The very first step is the collection of the sample. Your healthcare provider will take the sample from your respiratory material found in the nose. 

Healthcare providers use a swab stick with a soft tip on a long and flexible stick. The stick goes into your nose to collect the respiratory material. The nose swabs are of different types, such as nasopharyngeal that go into the nasal cavity for collection. The other type of swab includes nasal swabs that collect material inside the nostrils. There is a tube that holds the collected material for the COVID-19 PCR testing.

The second step of the PCR test is the extraction. The laboratory workers check the sample and isolate the genetic material.

The third step involves the use of different chemicals and enzymes along with the PCR machine called a thermal cycler. The method of healing and cooling cycle boosts the targeted genetic material of the test tube. Chemicals in the test tube produce a fluorescent light if SARS-CoV-2 is found in the tube. Special software is used to check the signal for the positive test results.

How long does it take for PCR coronal virus test results?

It may take 24 hours to get the results of the coronavirus if the sample reaches the laboratory on time.

Positive test results mean that you have an infection with the virus. It can be an asymptomatic infection. But people with more symptoms may have COVID-19. Many people do not need any special treatment as they can recover on their own.

Negative test results mean that you are not infected with the virus at the time of the test. But a negative test report does not say that you are protected in the future.

People often get confused about what test for COVID-19 is more accurate. According to experts, the antigen test is not as accurate as PCR. A person still needs to get a PCR test done if the antigen test is performed or whatever the resulting test is.

You should be careful during the pandemic as you may experience some symptoms of COVID-19 if you have been exposed to the virus. Make sure that you get medical help as soon as possible.
