COVID-19, causing current pandemic is a RNA virus with a single stranded RNA (ss RNA) in a protein envelop called capsid. One of the most reliable diagnostic test for COVID-19 is the Quantitative Polymerase Chain Reaction (q-PCR) test. This test involves collecting a nasal and a throat swab from the patient, transportation of the sample, extraction of ss RNA from the virus particle present in the patient sample and finally amplification of target viral genes by quantitative PCR.
