This test measures antibodies that target the spike protein of the SARS-CoV-2 virus. The spike protein is the part of the virus that attaches to human cells and is the target of all currently approved COVID-19 vaccines. Antibodies against the spike protein are considered particularly important because they can neutralise the virus and prevent infection. Qualitative and Quantitative Results: This test provides both a qualitative result (positive or negative) and a quantitative measurement of antibody concentration. The quantitative result is reported in binding antibody units per millilitre (BAU/mL), allowing you to track changes in your antibody levels over time. What Positive Means: A positive result indicates that you have developed antibodies to the SARS-CoV-2 spike protein. These antibodies may have developed in response to COVID-19 infection, COVID-19 vaccination, or both. Spike protein antibodies are produced following all currently approved vaccines. What Negative Means: A negative result means spike protein antibodies were not detected. This could indicate no prior infection or vaccination, testing too soon after infection or vaccination (antibodies may take 2–3 weeks to develop), antibody levels that have waned below the detection threshold, or immunocompromised status affecting antibody production. Important Note: While antibodies indicate an immune response, the level of antibodies required for protection is not definitively established. A positive result does not guarantee immunity, and a negative result does not necessarily mean you are unprotected, as cellular immunity (T-cell response) also plays a role in protection. Results should be interpreted by a healthcare professional.
This test is for screening and information only — it is not a medical diagnosis or professional advice. Please have your results reviewed by a qualified doctor or healthcare provider who can explain what they mean for your personal health situation. If your results show anything outside the normal range, or if you're worried about your health, see your doctor as soon as you can. Don't change any medications or treatments based on these results alone — always talk to your healthcare provider first.

Frequently asked questions
It means your immune system has been exposed to SARS-CoV-2 — either through infection, vaccination, or both. Antibody levels decline over time and do not directly correlate with protection from future infection.
No. Antibody tests detect past exposure, not current infection. For diagnosing active COVID, a PCR or lateral flow test is needed.
No. This test is not affected by food or drink.
