Wait at least 6-8 weeks after vaccination before getting a titer test. Testing too soon after immunization may show inadequate antibody response even though immunity is developing.
Results are reported as positive (immune) or negative (non-immune). Some tests provide quantitative values. If results show insufficient immunity, a booster vaccine may be recommended by your healthcare provider.
Once your Immunity Testing results are ready, you will receive a detailed report showing your values alongside reference ranges. It is important to review your results with a licensed healthcare provider who can interpret them in the context of your overall health history, symptoms, and any medications you are taking.
If results fall outside normal ranges, your doctor may recommend follow-up testing, lifestyle changes, or treatment. For normal results, your provider can advise on appropriate screening intervals based on your age, risk factors, and health goals.
