COVID-19 Spike Antibody Test
What is a semi-quantitative COVID-19 antibody test?
The SARS-CoV-2 Total Antibody, Spike, Semi-Quantitative test is intended to aid in identifying individuals with an immune response to SARS-CoV-2 (COVID-19). The presence of COVID-19 antibodies typically indicates a recent or prior infection. People who have been vaccinated with a SARS-CoV-2 spike or receptor-binding domain vaccine may show positive results with this test. However, the clinical significance of a positive antibody result for individuals who have received a COVID-19 vaccine is unknown.
The results of this test cannot indicate the degree of immunity or protection that a person has from reinfection with the COVID-19 virus. The results of this test cannot determine how long ago a person may have been infected.
What does a COVID-19 antibody Test show?
Results for this test provide a semi-quantitative value for the antibody level detected.
An indeterminate result is also possible. An indeterminate result can happen if you do not have enough antibodies in your blood for the test to detect, such as if you test too soon after becoming infected. You will likely need to be retested in order to confirm whether or not you have antibodies in your blood.
Can an antibody test be used to diagnose COVID-19?
No. The results of this test can neither diagnose nor rule out an active infection with COVID-19.
How accurate is the COVID-19 Antibody Test?
The sensitivity and specificity of this test are estimated at 99%. Sensitivity is a measure of how well a test is able to detect people who are infected (positive cases). Specificity is a measure of how well a test can detect people who are NOT infected (negative cases).
Turnaround for this test is typically 1-3 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Detection Period:
It can take up to 3 weeks for your body to develop antibodies after SARS-CoV-2 infection or after receiving the COVID-19 vaccine or boosters, so you should wait to get an antibody test until 3 weeks after your symptoms started, after testing positive, or receiving a vaccine or booster.
