How many days after tb test is it read?

My doctor specifically told me that the reading has to be done strictly within 48 to 72 hours. He said if you come after 72 hours, the skin reaction might fade or change, making the result completely invalid. So plan your clinic visit accordingly.

Yes, it must be read within 48 to 72 hours (2 to 3 days). Don't scratch the area in the meantime.

The test needs to be read in 2 to 3 days. While you wait, just eat simple, clean food and avoid touching or putting any home creams on the injection site, as it might mess up the skin reaction.

The Mantoux test requires you to return to the doctor after 48 to 72 hours. Do not let them read it before 48 hours or after 72 hours, as the measurement of the swelling won't be accurate.

Hey, don't stress too much about the bump on your arm! Just go back to the clinic exactly 2 or 3 days after the injection so the nurse can look at it. It's a very standard process, you'll be fine.
