Best Answer

Your doctor or nurse will perform a TB test by injection a solution called PPD under the skin of your forearm. You will have to go back 48 - 72 hours later to have it read (see if your skin reacted). Then one week later they do another TB test repeating the same procedure of injecting and then reading it 2 or 3 days later.
