My TB (tuberculosis) test is positive, but I don't feel any symptoms. Why?

Chest X ray

Tuberculosis
It is possible to have active Tb with very little symptoms especially early on. However, it is more than likely that you carry the germ for Tb in a dormant form, this is called latent Tb. No symptoms are expected with latent Tb.

Do all people from Jamaica or any small island always show a positive tuberculosis test?

Only if immunized

Tuberculosis
If immunization was in effect on that island (Cuba immunizes against TB), then the skin test will be positive. You need to know that information in order to interpret the skin test results of anyone from any of the islands. I don't know if immunization is in effect on all the Carribean islands.

Could you get anegative on your tuberculosis test even though you got a positive the previous time?

Possibly

Mycobacterium_tuberculosis_infection
I believe it could be possible if you now have marked immunosuppression. Additionally it could have been administered or read incorrectly on one of those occasions.

Could it be okay to retake a tuberculosis test after testing positive?

Generally not

Mycobacterium_tuberculosis_infection
If you are speaking of the skin test the answer is no, as it usually remains positive for years and years even after successful treatment. There is a blood test for latent (silent) TB that can be repeated following initial, successful treatment

Dr. Lokesh Guglani answered:

Is the tuberculosis test positive if you have a bump there a week after the test was administered?

No

Mycobacterium_tuberculosis_infection
The PPD test has to be measured & interpreted within 48-72 hours after administration of the test. Any swelling/induration noted a week after the initial intradermal injection cannot be taken as evidence of a positive test.

Dr. Lokesh Guglani answered:

How can the tuberculosis test work?

Two forms

Tuberculosis
There are 2 TB tests - PPD shot (given in forearm & swelling at that site is measured after 48-72 hours) and a newer blood test (Quantiferon) that tests for immune response in blood cells. Both tests assess the response of T lymphocytes to several proteins that are present in the TB bug. Positive test would only mean that you have been exposed to TB bug. More tests are needed for active infection
