How to know if a tb skin test is positive?

Oh, I totally get the anxiety waiting for these test results! For a TB skin test (Mantoux test), a nurse or doctor needs to examine your arm 48-72 hours after the injection. They don't just look for a red spot, but for a raised, firm bump (induration). The size of this bump, not the redness, determines if it's positive, and the measurement is specific. Don't try to measure it yourself, let the professional do it.

So, for the TB skin test, you usually get an injection, right? And then you have to go back in 2 or 3 days. A nurse or doctor will check your arm. They are looking for a firm, raised bump, not just a red area. The size of that bump tells them if it's positive. It's really important to let them check it because they have specific measurements. Don't try to guess it yourself!

For a TB skin test, there are no home remedies, beta. You have to go back to the doctor or nurse after 2-3 days. They will check the site where they gave the injection. They are not looking at just the red mark, but a raised, hard bump on your skin. They will measure it to see if it is positive. It's very important to follow up with them.

Ah, the old TB skin test, where you walk around feeling like a human pincushion for a few days! To know if it's positive, you absolutely need to go back to the clinic after 48-72 hours. They won't just look at the redness; they'll actually measure the *bump* or *hardened area*. If it's a certain size, then bingo, it's positive. So don't try to eyeball it yourself, let the professionals do their magic!
