I've had a yearly skin test ever since I started on Remicade. The TNF blockers can block the immune system factors that keep TB infections inactive, leading to very severe TB illness. The test is to make sure you haven't been exposed, infected and harboring the bacterium.
Interestingly, I just had my annual with my GI and he ordered a Quantiferon gold assay to test for TB. He said it's more accurate because they've found that occasionally Remi will interfere with the reaction to the skin test. I'll get it drawn when my PCP draws my routine quarterly blood tests.
