I'm 25 years old. I had a sputum test 2010 but results to negative. Now I had a PPD test 3 days ago. When I have it read by my doctor today, the reaction is not normal to a positive result, mine produce pus but there is no redness. According to the doctor It is a exaggerated reaction and suggest me to repeat the PPD test. Please I need your opinion regarding this. thanks
The test is performed by injecting 0.1 ml of tuberculin purified protein derivative (PPD) into the inner surface of the forearm. The injection should be made with a tuberculin syringe, with the needle bevel facing upward. It is an intradermal injection. When placed correctly, the injection should produce a pale elevation of the skin (a wheal) 6 to 10 mm in diameter.
The skin test reaction should be read between 48 and 72 hours after administration. A patient who does not return within 72 hours will need to be rescheduled for another skin test. Some persons may react to the test even though they are not infected with M. tuberculosis.
In general, there is no risk associated with repeated tuberculin skin test placements.
