What happens if you have allergic reaction to tb skin test does it mean that you have tb?
A doctor has provided 1 answer
Was it allergic?: Was the reaction an allergic reaction or was it a positive sin test? There are components in the test that one can react to in an allergic fashion...The area can be red and itchy. But if it is raised and red and approx the size of a dime, it is a positive test and means you have been exposed to tb.
