How to read a tb mantoux test?

It can be quite uncomfortable to wait with that itchy bump on your arm. Please avoid applying any home remedies, ice, or aloe vera gel on it, as it needs to be read in its natural state. Just be patient and let the clinic handle it.

I am not very sure about the exact medical measurements, but I know it's calculated based on the size of the hard swelling, not the redness. It's best to go back to your clinic on time so you get an accurate and safe result.

When I got this done at a leading hospital, the nurse marked the area with a pen. They told me clearly that self-reading is not reliable because the measurement depends on your health history. Ask your doctor clearly what the millimeter reading means for you.

I totally get it, waiting to see if that skin bump grows can make you really nervous. Just try not to scratch or touch the area while you wait. It's always best to let the lab technician or doctor measure it properly with their scale.

Please keep your mind peaceful while waiting for the results. Our bodies have great strength to heal, and getting tested is just a step to take care of yourself. Trust the doctors and stay positive.

Remember, you must get the test read between 48 and 72 hours after the injection. If you miss this window, the result won't be accurate and you'll have to get it done again. The doctor will measure the width of the hard bump in millimeters.

Hey! I had to get this test done for my college admission. Don't worry if it looks a bit red, that's super common. Just go back to the lab after 2-3 days and they will measure it with a small ruler in two seconds.

I was checking my arm every hour when I had this test, worrying that the bump was growing too big. If you are feeling anxious, please try to distract yourself. It is almost always less scary than we think once the doctor actually measures it.

When we have existing health conditions, our immune systems can react differently. That's why you should never try to read a Mantoux test at home. Go for your scheduled follow-up so the doctor can document it correctly.

I agree, make sure you don't apply any band-aids or creams on the injection site as it can alter the reading.

I panicked completely when my skin turned red and swollen after the injection, thinking I had severe TB. But when I went back, the doctor explained that redness is normal and only the hard induration matters. It turned out to be completely fine, so don't worry.
