How is the COVID-19 Virus Detected using Real Time RT-PCR?
WebMost 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. WebThe changes may be minor (low-grade) or serious (high-grade). Most of the time, minor changes go back to normal on their own.
