COVID-19 | Finger Stick Dried Blood Collection
This blood specimen tests for antibodies which have been found to be highly sensitive biomarkers in infectious disease diagnosis. Previous studies on SARS, MERS, and more recently the ones on SARS-CoV2 have shown IgM antibodies to appear about 3 days from infection and IgG antibodies appear after 8 days. Profiling an individual’s antibody response is the only way to determine infections with few or no symptoms.
This type of test is more for those who have already shown symptoms for at least 3 days and beyond.
