Help PPD Positive; 5 mm or more than 5 mm

In HIV pt.
If induration is equal to 5 mm, does it mean positive ? or it should be larger than 5 mm to consider positive.
thanks

In MTB2(page 155) it says induration LARGER than 5mm is considered positive in HIV patients. However, I do not think that an induration of exactly 5mm will be considered a negative PPD or that they would put such equivocal figures on the exam. In practise though, when the PPD is positive or inconclusive it still has to be followed up with a CXR to confirm.

Hope this helps

Ok I hear you. Like I said, according to MTB2 it is induration larger than 5mm that is considered a positive test in HIV patients.

In Healthcare workers, induration larger than 10mm is considered positive.

All the best in your exams.

Health workers with more than 10mm need to do xray. If xray is negative, GIVE Prophylaxis.
