Hope, I get that too. It is sort of funny but very strange. I had a single mastectomy so I have one natural breast & nipple and one implant reconstructed breast with no nipple. (I replied to this post because the itching problem happens to some of us whether we've had reconstruction or not).
If it has been many years since a person was infected with TB, his or her initial skin test may be negative, because of waning immunity. Subsequent tests may be positive, however, because the initial tuberculin placement stimulates the immune response to the test.
From infection to development of a positive TB skin test reaction (the incubation period) is approximately 2 to 12 weeks.The risk for developing active disease is the highest in the first two years after infection and development of a positive TB skin test reaction.fter an exposure to infectious tuberculosis, a TB skin test reaction of 5 mm induration or greater is considered positive. You will then be evaluated for signs and symptoms of active tuberculosis (cough lasting for more than three weeks, bloody sputum, fever, night sweats, weight loss, loss of appetite, fatigue).
