A member asked:

Can you explain if it's safe to retake a tuberculosis test after testing positive?

A doctor has provided 1 answer

Repeat TB test: It is not a good idea to repeat a TB skin test if a previous test is positive as you can have a much larger reaction that may cause a problem. If you are required by work to have a screen for tB again , an X-ray is usually recommended.
