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.
As little as 5 millimeters of induration is a positive test for someone with an impaired immune system or a known TB exposure. A trained reader needs to interpret the TB test. Most people with a positive TB skin test donât recall symptoms of tuberculosis. They may have a normal chest X-ray, as well. Nevertheless, they still likely have a small number of tuberculosis bacteria hiding somewhere in the lungs.
