Clinical Significance

Clinical Significance

SARS-CoV-2 PCR (COVID-19)

Symptoms often develop an average of 5 days (range 2-14 days) after SARS-CoV-2 infection. Diagnosis of a current infection is made by having a positive RT-PCR swab test usually within 3 days of infection and may become undetectable after 2-4 weeks from disease onset. Detects two regions of the Nucleocapsid gene (N-Gene) of SARS- CoV-2 and produces one target signal.
 

  • This assay currently detects all known variants, but does not distinguish between them.
  • Detects SARS-CoV-2 RNA with high sensitivity as low as approximately 67 copies per mL.

SARS-CoV-2 PCR (COVID-19)

Symptomatic SARS-CoV-2 (COVID-19) infections usually resolve without treatment, and vaccination is recommended for prevention. Severe cases may require hospitalization and/or medical treatment.
