LoD is the lowest detectable amount of the test target that a test can reliably distinguish from zero. It is a very important number,
Immunofluorescence Assays use antibodies with a fluorescent marker to bind to a target (here the SARS-CoV-2 n-protein) which can then be read by a detector
The Ct or threshold cycle value is the number of amplification cycles a PCR test needs to perform before a sample shows a positive result.
Antibodies are proteins produced by our immune system and are key to fighting a COVID-19 infection.
