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.
TB diagnostic tests. These are TB tests which can be used to determine if someone has latent TB, which means that they are infected with TB bacteria. There are also TB tests, which when considered alongside other factors, such as whether someone has TB symptoms, can confirm a diagnosis of active TB or TB disease.Even if a person has symptoms, TB is often difficult to diagnose, and is particularly difficult to diagnose rapidly.alse positive results happen with the TB skin test because the person has been infected with a different type of bacteria, rather than the one that causes TB. It can also happen because the person has been vaccinated with the BCG vaccine. This vaccine is widely used in countries with high rates of TB infection.
