Antibody Test
An antibody test is a type of blood test that checks for the presence of antibodies – proteins made by your immune system in response to an infection or vaccination. It helps determine whether your body has been exposed to a virus or bacterium in the past and whether it has mounted an immune response. Often included in a wider blood panel, an antibody test provides useful insights into your immune history and potential immunity to specific diseases.
Why is an Antibody Test Carried Out?
Antibody tests are commonly used to detect previous infections, assess immune responses, or support diagnoses when symptoms have resolved. They are particularly useful when the active infection has passed but confirmation of exposure is needed. In clinical settings, they help inform decisions about care, immunity monitoring, or vaccination strategies.

Can an Antibody Test tell if I’m immune to a virus?
In some cases, yes. If your body has developed antibodies after infection or vaccination, an antibody test can confirm their presence. However, having antibodies does not always guarantee full immunity. The level, type of antibodies and how long they remain in the body can vary depending on the virus and individual immune response. Your doctor will interpret the results in context to determine what they mean for your protection.
Do I need to have a repeat Antibody Test over time?
Repeat antibody testing may be recommended if your immunity needs to be monitored over a longer period; for example after vaccination or if you are immunocompromised. In some cases, testing at intervals helps track the duration of your immune response or identify when further medical advice or boosters might be needed.
Can Antibody Tests show if a vaccine worked?
Yes, antibody tests can help confirm whether your body has produced an immune response after vaccination. They do this by detecting antibodies specific to the virus targeted by the vaccine. This can be particularly useful for people with underlying health conditions or those whose response to vaccines may vary.
