I had a TB skin test done and it was red,swollen and raised but quickly began to fade to a very small lump?
I had a positive result in 1991.
Thanks a lot!
Answers: Folks here don't seem to know much about the PPD or the skin test for TB. A TB syringe is used to inject 0.1 ml of the terbursol under the skin. This should produce a bubble when the fluid is placed just under the skin. Usually in 2 days it is "read" but it can be done at day 3 as well. A slightly raised red area is a positive reading. It does NOT mean you have TB, it simply means you have at some point in your life been exposed to TB. The next step is to do a chest xray to be assured you are not in an active stage of the disease and if you were you would be treated with a 6 to 12 month course of antibiotics. Meantime if any time you have a positive TB skin test you should NEVER have that repeated as it will always be positive, you should skip the skin test and go directly to the chest xray. There is no such thing as a "false" positive since the test doesn't work that way exactly.
i know the test fot TB starts out at a raised hard bump under the skin and if it doesn't go away with in the two days then you have it... if it went away then its negative but where you have had a positive once before i would go back to the doctor just to be sure.
Seems like it's positive again.
means u don't have it...
Yes, they inject you (usually your hand from my experience) with a few mLs of a fluid. If it goes away, you are fine. There is a bump because of all the fluid. Another way is they poke you with a little thumb-tac like object, that has 4 little pins/needles, one at each corner. If either of these are swollen/red and irritated after a couple of days, then you have TB. If they go away quickly, you are fine.
Gazey Goo said it all. They are correct...10 points.
