COVID-19 (SARS-CoV-2) testing options by PCR and IgG Antibody
COVID-19 (SARS-CoV-2) PCR assay
Nasal/Throat swabs collected using BD dry swabs/Remel M4RT/Copan 321C UTM or Copan 147C.
Samples should be taken from symptomatic patients between days 1-5 from onset of symptoms.
Specimens should be sent to the laboratory at ambient temperature in Category B packaging and labelled as containing HIGH RISK specimen.
For best results, please send samples on the day they are taken. However, samples are stable at ambient temperature for 3 days for wet swabs, and up to 6 days for dry swabs.
Infection with SARS-CoV-2, an RNA virus, is diagnosed using reverse-transcriptase real-time PCR. The assays used at TDL show a minimum sensitivity of 98% and a specificity of 100%, with no cross-reactivity with other viruses.
