Test Procedure





How It Works

is a lateral flow assay that detects the presence or absence of the SARS-CoV-2 nucleocapsid antigen, the protein that encapsulates SARS-CoV-2 RNA (genetic material) within the virus.

The lateral flow assay (LFA), also known as lateral flow immunoassay, uses antibodies labelled with an enzyme that emits colour to detect a specific target.

  1. The sample is loaded onto the sample pad which controls the flow of the sample through the rest of the cassette.
  2. The sample will flow through the conjugate pad which contains the labelled antibodies. If SARS-CoV-2 is present, the labelled antibodies will bind to SARS-CoV-2 in the sample and continue to migrate along the test.
  3. The sample will continue to move along the nitrocellulose membrane where binding reagents will bind to the target at the test line. If SARS-CoV-2 is present, a coloured line will form. How clearly the line shows up depends on the amount of SARS-CoV-2 present. The control line should also form if the assay was correctly performed. If there is no formation of the control line, the test is not valid.
  4. The absorbent pad at the end absorbs any excess sample.
