Abstract

RT-PCR (Reverse Transcription Polymerase chain Reaction) is the most commonly used laboratory test for detection of COVID 19 antigen. The test is done on samples obtained by using the Nasopharyngeal swab, Oropharyngeal swab, Sputum, bronchial secretions obtained via bronchial lavage or Saliva. The nasopharyngeal or oropharyngeal are currently commonly used for the same but several studies have shown that from the point of view of diagnosis, nasopharyngeal and throat swabs are less sensitive and specific as these material obtained from these areas reportedly contain less Viral RNA than sputum or saliva. Hence a more convenient and specific sample to test would be the saliva. The advantages of testing saliva (for RT-PCR) over other samples are discussed in this article.
