Check whether the test is qualitative or quantitative
Look for the specific antibody type reported: IgG, IgM, or total antibodies
A positive result means antibodies were detected
A negative result means antibodies were not detected or were below the test’s threshold
IgM may suggest a recent or current immune response
IgG may suggest a past infection or prior vaccination response
Total antibody tests detect one or more antibody types but do not specify which
Compare the result to the lab’s reference range or cutoff value
Review the test date in relation to recent infection or vaccination
Confirm whether the test is for infection history or vaccine response
Do not use antibody results alone to determine current infection status
Follow up with a healthcare professional for interpretation in context of symptoms and exposure history
