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.
Tuberculosis, also called TB, is an infection caused by a bacteria. TB usually affects the lungs, but it can spread to the kidneys, bones, spine, brain, and other parts of the body. The most commonly used skin test to check for TB is the PPD â purified protein derivative. If you have a positive PPD, it means you have been exposed to a person who has tuberculosis and you are now infected with the bacteria (mycobacterium tuberculosis) that causes the disease. Not necessarily.
