COVID-19 is commonly diagnosed by quantitative fluorescence real-time reverse transcriptase-polymerase chain reaction (qRT-PCR) (1, 2). The test is the sequential action of two enzymes–an ...
Ideally, gene expression studies by quantitative RT-PCR (qRT-PCR) should be performed using RNA from homogeneous cell populations. Frequently, this means performing qRT-PCR using picogram amounts of ...
A polymerase chain reaction (PCR) test detects genetic material from a pathogen or abnormal cell sample. Ways of collecting samples include a nasal swab, a saliva swab, or taking a sample of blood.
