If you’re concerned about tuberculosis (TB), you may have heard of the TB antigen test. This test is used to determine if you have been exposed to TB bacteria. At Nao Medical, we offer same-day appointments for urgent care and skin testing in NYC. Here’s what you need to know about TB antigen test results.
What is the TB Antigen Test?
The TB antigen test, also known as the TB skin test or PPD test, is a simple and painless test that involves injecting a small amount of fluid under the skin of your forearm. This fluid contains a protein from the TB bacteria. If you have been exposed to TB bacteria, your immune system will react to the protein and cause a small bump to form on your skin.
What Do TB Antigen Test Results Mean?
If you have a positive TB antigen test result, it means that you have been exposed to TB bacteria at some point in your life. However, it does not necessarily mean that you have active TB disease. Further testing, such as a chest x-ray, may be needed to determine if you have active TB disease.
If you have a negative TB antigen test result, it means that you have not been exposed to TB bacteria or that your immune system did not react to the protein in the test fluid. However, a negative result does not necessarily mean that you do not have TB disease. It can take up to 8 weeks for your immune system to react to the TB bacteria, so you may need to be retested if you have been in close contact with someone who has TB disease.
What Should I Do if I Have a Positive TB Antigen Test Result?
If you have a positive TB antigen test result, it is important to follow up with your healthcare provider. You may need further testing, such as a chest x-ray, to determine if you have active TB disease. If you do have active TB disease, it is important to start treatment as soon as possible to prevent the spread of TB to others.

FAQs
What is the difference between a TB antigen test and a TB blood test?
A TB antigen test involves injecting a small amount of fluid under the skin of your forearm, while a TB blood test involves drawing blood from your arm. Both tests are used to determine if you have been exposed to TB bacteria, but the TB blood test is more expensive and may not be covered by insurance.
Is the TB antigen test accurate?
The TB antigen test is generally accurate, but it can produce false-positive or false-negative results. False-positive results can occur if you have been vaccinated with the BCG vaccine or if you have been exposed to non-TB mycobacteria. False-negative results can occur if you have a weakened immune system or if you have been recently infected with TB bacteria.
