How many days to read tb skin test?

My grandchild got a TB skin test done recently. The clinic asked us to come back after a few days. Exactly how many days after the TB skin test should it be read for accurate interpretation?

Bhaiya, sui lagane ke do se teen din baad doctor ke paas jaana hota hai dikhane ke liye. Wo hath par gol nishan ko napte hain. Beech mein wahan pani mat lagne dena aur dhyan rakhna.

Yes, it is exactly 48 to 72 hours. Make sure you don't scratch or scratch the injection site while waiting.

I know how stressful it is to wait those 2 to 3 days (48 to 72 hours) for the reading, constantly staring at your arm. Try to distract yourself; it is a very routine test and most of the time it is just a standard check.

It takes 2 to 3 days to get the skin test read. On the bright side, you don't have to skip any meals or go on a diet for this test, so you can eat whatever you want while you wait!

You will need to return to the doctor in 48 to 72 hours to get the result read. It is a very simple process, so please don't worry.
