I just had my tb skin test on thurs and i noticed my skin is a little bit elevated at the site of injection with erythema around it??positive result??

Get it read: Get it read at a laboratory from a technician . It's not the redness but the induration that matters . So better get checked at 72 hrs .

Depends: on the onset of redness/elevation from the time testing and the diameter of the elevated area, also if you have had BCG vaccination as a child, that can be very well a false positive test, alternate blood testing can be used, good luck
