Splet31. dec. 2024 · Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cycle threshold (Ct) has been suggested as an approximate measure of initial viral burden. The utility of cycle threshold, at admission, as a predictor of disease severity has not been thoroughly investigated. Methods and findings SpletMost tests that detect the ribonucleic acid (RNA) or genetic fingerprint of the virus that causes COVID-19 (e.g., a polymerase chain reaction, or PCR test) use a process where specific bits of the genetic fingerprint are amplified using a temperature cycling reaction that repeats up to 45 times. These are called amplification cycles.
