Depends: That depends on your age, other health conditions, and whether you recently went from having a negative PPD to a positive one.  In some cases, we treat with a 9 month course of isoniazid, or a shorter course of Isoniazid and rifapentine, to eliminate the latent bacteria.

Question 5

what does a positive ppd test feel like?

Accepted Answer

Firmness: The diameter of the circle of hardened skin at the site of the PPD is measured, and depending upon who you are, what underlying diseases you may have, what medications you are taking, it is read in 48 hrs.  Do not measure the area of redness, only the area of firmness (induration).  Otherwise there are seldom other symptoms.

Not necessary: A negative PPD simply means you don't have a lump at the site of the PPD injection 48-72 prior.  This means the skin appears normal. If there is a raised bump at the site, then depending on your particular risk factors or history, you may be positive.  The next step would be a chest x-ray.  But, if no bump, then negative.

what does a positive ppd test look or feel like?

Accepted Answer

Depends: Who are you, what underlying conditions do you have.   Generally, for a normal non-hiv adult, a one centimeter area of induration (hardness of the underlying tissues) is considered positive.   Do not count areas of redness.  If positive it means you have living mycobacteria somewhere in your body, although these can remain inactive the rest of your life.

TUBERCULIN POSITIVE:: If read positive, it can take about a week afterwards to diminish slowly. Sometimes it can cause a blister when there is strong positive result, can have a thin scab or dry skin with some itching.
