I got a tb test and my doctor measured the red partthat area definitely wasn't 12 mm. do i have tb?
A doctor has provided 1 answer
Depends on risk: The body reacts if it has an adequate number of immune cells to respond and cause an area that is similar to an insect bite. The measurement of the swelling does not include un swollen redness on the skin. The measurement is evaluated in the context of risk factors. For example, if someone has hiv, then a test result of 5 mm may indicate a positive test. Please check with your clinic.
