We offer both Abbots & Roche ECLIA test
This test is a venous blood draw test, which gets sent off for analysis.
IgG antibody testing can tell whether a person has been previously infected, as the host immune system reacts to the infection by SARS-CoV-2 by producing antibodies from a few days to two weeks after the onset of symptoms. Specific IgG antibodies are produced in the later stages of infection to SARS-CoV-2, and are detectable after RNA is no longer detectable.
The persistence of IgG antibodies allows identification of people who have been infected by SARS-CoV-2.
This test has a minimum sensitivity of 98% and a specificity of 100%, with no cross-reactivity with other viruses.
IgM Antibody Testing can give indication of current infection.
PCR (polymerase chain reaction) samples can come from several different sites in the patient. The simplest is the nasal swab taken from well inside the nose. The back of the throat is another option.
To find evidence of the virus, researchers use PCR to copy and amplify any segments of viral genetic code found in the sample, which makes it easier to detect. This typically involves adding reagents and enzymes, and raising and lowering the temperature of the mixture, known as thermal cycling.
Antigen testing reveals whether someone has a current infection and could therefore pass Covid-19 on to others. PCR is the gold standard in viral diagnostics.
