The COVID-19 Nose Swab PCR Test is the most effective and recognized diagnosis test for COVID-19. The person who has COVID-19 is called COVID Positive. The negative is probably you don’t have COVID-19.

What is RT-PCR to diagnose COVID-19?

COVID-19 is caused by the SARS-CoV-2 virus. It is an RNA virus that causes a cell to multiply and survive in healthy conditions. The RT-PCR test is therefore for SARS-CoV-2 RNA identification. The RNA is converted to DNA using a process known as the “Reverse Transcription” for virus detection.

SARS-CoV-2 RNA is generally detectable in respiratory paths. In this context, a sample is collected from both upper and lower respiratory specimens (such as nasal and nasopharyngeal swabs, sputum, aspirates in the lower respiratory tract, bronchoalveolar lavage, and nasopharyngeal aspirates).
