SARS-CoV-2 Semi-Quantitative Total Antibody, Spike is a comprehensive test that measures all antibody types (IgG, IgM, IgA) against the SARS-CoV-2 spike protein receptor binding domain (RBD). This test provides both qualitative detection and semi-quantitative measurement of total antibody levels, offering insight into the overall immune response to COVID-19 infection. The test detects antibodies that develop in response to natural infection, providing evidence of previous SARS-CoV-2 exposure. The semi-quantitative nature allows healthcare providers to assess the magnitude of the antibody response, which may correlate with the severity of infection or immune protection. This test is particularly valuable for evaluating patients with suspected COVID-19 exposure, monitoring immune response in recovered patients, and assessing antibody levels in individuals who may have experienced asymptomatic infection.
