How is pcr used to detect viral infections
WebReverse transcriptase (RT-PCR) can be used to detect viral mRNA transcripts in peripheral blood leukocytes independent of the presence of DNA. The absence of circulating mRNA is associated with a lack of CMV-associated symptoms, irrespective of the presence or absence of CMV DNA, while its presence is detected only in the setting of disease [ 38 ]. WebThe most widely used assay for COVID-19, molecular, or real-time reverse transcriptase polymerase chain reaction (RT-PCR) testing, is used to detect acute infection with SARS-CoV-2 in the upper and lower respiratory tract. RT-PCR is relatively simple to administer and highly sensitive.
