There are false positives on PPD's. Tuberculosis affects many organs other than the lungs. It's an unexpected disease in the U.S.

i dont think it is they give you a lung xray or a TB skin test i think coughing,coughing up blood,night sweats

TB is a difficult disease to diagnose mainly because it is an indolent and insidious disease. TB bacteria grows slowly, and can infiltrate an organ before any symptoms appear. Because they are slow growing, they are also difficult to grow in culture, making their identification difficult. When a patient will present with symptoms is hard to predict, and the symptom depends on the organ it affects. While most commonly affecting the lungs, it can infects virtually any organ in the body, so the presenting symptoms can vary widely.

A tuberculin skin test can be falsely positive secondary to immunizations given in some countries. People who have a positive ppd, then have a chest x-ray. If the illness has inhabited another organ other than the lungs, it may be difficult to find/diagnose. This is extraordinarily rare.
