Pcr Results Not Detected. 10 days approximately after infection the virus is infectious. Real time RTPCR is a nuclear-derived method for detecting the presence of specific genetic material in any pathogen including a virus.
You are infected with COVID-19 but the test was done too early to detect the virus OR. If the virus isnt detected within 40 amplification cycles the test result is negative. Your result could be indeterminate if.
A polymerase chain reaction PCR test is performed to detect genetic material from a specific organism such as a virus.
Significance of Not Detected but Amplified Results by Real-Time PCR Method for HPV DNA DetectionResearch Article Report by BioMed Research International. But then the virus is still present many days after. Please be re-evaluated immediately for worsening symptoms such as shortness of breath or lightheadedness. If viral RNA is detected in 40 cycles or less the PCR machine stops running and the test is positive.
