you can usually tell if the skin is red and if the punctured skin is more elevated than the surrounding skin.
it depends, because sometimes it's a false positive. so it always best to get another shot if it is positive.
if its really red and puffy.
It is contraindicated to have a second TB test after a previous positive test result.
exposure to TB and having had a BCG vaccine.
A positive TB test can mean you have been in contact with someone who has TB or you have TB. I now also show positive to TB as I went on the trial medication which I now am immune to TB. So tests will always come back positive but its not active. There is something called Valley Fever in the southwest. It is a spore that comes out of Death Valley that attacks the lungs. People who have had Valley Fever test positive for T.B.
If you get a positive Mantoux test it means that you have purified protein derivative. This test is used to test for TB or Tuberculosis. If you get a positive test, further testing is required to see if you actually have Tuberculosis.
the results will not be accutare... and you will get a positive result.
No, not necessary. Positive TB test just mean your immune system has been exposed to the TB antigen. This could be from false positive (no test is perfect), allergy, recent BCG vaccine (unlikely in the US) or you really were exposed to the bacteria.Just because you're exposed to the bacteria also does not mean you will get the disease; your immune system is an excellent line of defense.Anyhow, TB can actually affect many organs in your body, but the most concerning one is pulmonary because it's the most common and most easily pass from one person to another. This is why chest x-ray is the next screening test for people with positive TB skin test. However, people with active TB usually have other symptoms like fever, chills, night sweats, weight loss, cough, shortness of breath, cough up blood, ect.Current recommendation is that you should take INH (antibiotic) for 9 months if you have positive TB skin test. This is because you may carry the TB bacteria within your body somewhere even though they are not causing any active disease. Chest x-ray will be your screening test from then on because you will be positive again with future TB skin test.
it means you were exposed to the virus, you need to have a chest x-ray to confirm a TB test. If the virus is active a sputum sample is needed to confirm a diagnosis of TB
being near someone with tb
No. It would be TB positive.
It can irritate the site and give you a false positive
