What is a RT-PCR test?

PCR Test is also known as RT-PCR. It is basically a test where a swab is taken from your nostril and throat to ascertain the presence of the Covid19 virus. Medically, it is a nasopharyngeal swab to collect specimens from a patient to test for the presence of the 2019 Novel Coronavirus (SARS CoV-2). PCR Test is a type of Nucleic acid Amplification Technology.

How is the RT-PCR sample collected for COVID-19?

  • Step 1 – The patient must be seated in a comfortable position with the head tilted back slightly to make the nasal passages more accessible.
  • Step 2 – A flexible Cotton-Tipped Plastic swab is gently inserted into one of the nostrils (in some cases samples are collected using both nostrils). The swab is long enough to reach the passage that connects the base of the nose to the back of the throat. (i.e., nasopharynx, the upper part of the throat and behind the nose)
  • Step 3 – The swab is kept there for 10 – 15 seconds while being rotated around to collect the sample accurately and adequately.
  • Step 4 – Finally, the swab is removed gently and is immediately placed in a special container to be sent for analysis in the laboratory. The whole process takes approximately 30-40 seconds.

What might I experience during the RT-PCR sample collection?

A minor discomfort will be felt while the swab is inserted, including an urge to sneeze, cough, and teary eyes. However, these symptoms will reduce and go away after sample collection.
