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.
If you had the BCG vaccine and you have a choice of having a TB blood test or a TB skin test, it is better for you to have the TB blood test. This is because the TB blood test is not affected by the BCG vaccine. This means that your TB blood test will be âpositiveâ only if you have TB germs in your body. âpositiveâ TB blood test result means you probably have TB germs in your body. Most people with a positive TB blood test have latent TB infection. To be sure, your doctor will examine you and do a chest x-ray.
