- TB blood test – a test that uses a blood sample to ind out if you are infected with TB bacteria. The test measures the response to TB proteins when they are mixed with a small amount of blood. Examples of these TB blood tests include QuantiFERON ® -TB Gold In-Tube test (QFT-GIT) and T-Spot ® . TB test.his is because it can take several weeks after infection for your immune system to react to the TB skin test. If your reaction to the second test is negative, you probably do not have TB infection. TB blood tests TB blood tests use a blood sample to ind out if you are infected with TB bacteria.

It does not tell whether the person has latent TB infection (LTBI) or has progressed to TB disease.

QuantiFERON Testing The QuantiFERON TB Gold test (QFT-G) is a whole-blood test for use as an aid in diagnosing Mycobacterium tuberculosis infection, including latent tuberculosis infection (LTBI) and tuberculosis (TB) disease. This test was approved by the US Food and Drug Administration (FDA) in 2005. This test is currently NOT available from the South Dakota Department of Health because of the 12 hour processing requirement which makes the testing impractical at the current time.

TB Blood Test Benefits and Recommendations The QuantiFERON-TB Gold requires only a simple blood test. The patient, therefore, has no need to return to interpret skin test results, there is less chance of interpretation error, and far fewer changes of returning false positives when compared to the PPD. Better yet, results are returned in around 24 hours.

The TB blood test can be done instead of a TB skin test (Mantoux). There are two kinds of TB blood tests: QuantiFERON®-TB; T-SPOT®.TB ; You should have a TB blood (or TB skin test) if you: 1  have had frequent close contact with someone who has active TB disease, 2  have lived in a country where many people have TB, 3  work or live in a nursing home, clinic, hospital, prison, or homeless shelter, or. 4  have HIV infection or your immune system is not very strong.

Tuberculosis Skin Test (PPD Skin Test) Skin tests should be read 48-72 hours after the injection. The basis of the reading of the skin test is the presence or absence and the amount of induration (localized swelling). A negative test does not always mean that a person is free of tuberculosis. A person who received a BCG vaccine (administered in some countries but not the U.S.) against tuberculosis may also have a positive skin reaction to the TB test.

After two or three days, you must return for the TB skin test reading. You may have a swelling where the tuberculin was injected.
