Clinical Use | RML has initiated two assays for the semi-quantitative detection of IgG antibodies to the COVID 19 nucleocapsid and a second to the COVID 19 spike protein. The IgG antibodies to the nucleocapsid can only come about following a SARS-CoV-2 infection. IgG antibodies to the spike protein will follow an infection and/or a vaccination with a spike initiating vaccine. The assays will be valuable in discerning as to whether the patient has or has not had a COVID 19 infection or a vaccination. The semi-quantitative values will be important to determine the degree of antibody activity in seroconversion as well as following the status of the levels of antibody activity over time. They will be available in two formats. One is the COVID 19 IgG anti-spike and the other is COVID 19 IgG anti-nucleocapsid. The results will be reported as a relative value (i.e. positive or negative) as well as a semi-quantitative value. |
