Mantoux test is a test for tuberculosis. The test involves injecting a small amount of tuberculin (an extract of the causative bacteria) into the forearm skin, and the skin reaction measured 72 hours later.
This is the staff nurse who administered my tuberculin injection.
The nurse said the injection itself is quite painful, and claimed that she was quite nervous administrating Mantoux test for a "doctor".
It's an intradermal injection, meaning the stuff is injected right under the skin.
The injection site is left untouched for 3 days; no soap around the injection site during shower. The site is inspected and interpreted by an experienced medical personnel after 72 hours.
The skin reaction on my forearm, 72 hours after injected with the tuberculin.
Simply put, the induration (the reddish hardening) on the skin is measured to arrive to the diagnosis of tuberculosis. An induration of 10mm or more in people with no BCG scar indicates a positive reading for tuberculosis. In most people who are vaccinated against TB and hence, a BCG scar is present, a reading of 15mm or more is needed to indicate a TB infection.
8mm!
My skin induration measured 8mm (and yes, I do have a BCG scar)! That means I don't have TB! Fuhhh... On why I did this test, that's a story for another day!

there's a reason why you're not addressed as "experienced medical personnel"! the reddish central induration is measured, instead of the whole peripheral erythematous reaction. geddit?! in short, it IS 8.0mm!
