Question 1

i had a 2 part series tb test done, came back negative. that was back around 1/26/22. now for a new job another tb test needs to be done. is it save to have another tb test? it's just a poke to the arm?

Accepted Answer

: Yes, it is safe to repeat the test. If you had a skin test, you could use the results, verified by your doctor and present those to the new organization. A blood test can be used instead to the usual skin test.

Question 2

i had a tb test done last tuesday, the nurse said i am negative but i still have a red bump that looks like a mosquito bite on my arm.. is this nor...

Accepted Answer

TB Test: A positive test is measured by induration that is palpated on your arm - not by overlying swelling or bump

Question 3

can i drink alcohol with a tb test in my arm?

Accepted Answer

Yes: the result of the test is only related to your body's previous exposure to tb, and is not affected by alcohol

Question 4

i have pain in my elbow and its hard to move my hand after tb test. what is that mean?

Accepted Answer

Hard to say...: If you got the test and your arm swelled up shortly afterwards, its possible that either you had an allergic reaction to the test, had a test site infection, or had an unrelated injury while sleeping or (if you had a blackout) were otherwise not aware of your surroundings.  Go back to the doctor who gave you the test and have them look.

Question 5

tb test: neg >72 hrs but now large lump as time goes on? how long for mark to go away?

Accepted Answer

Negative, give time: As long as there was no hardened lump at the infection site within that first 72 hours that was greater than 15mm (or less if you have risk factors), you are still considered negative. It can take some people up to a week or so for the redness and swelling to recede. Try ice several times a day to help with any swelling.

Question 6

hi, i recently had a tb test. it looks round and red but no bump. it was read as negative by nurse buy after 5 days, the redness is still there.

Accepted Answer

Gradual disappearanc: No worries. The redness will gradually disappear.

Question 7

when you take tb test and  no bubble pops up is it negative?

Accepted Answer

A positive: Tb test is associated with elevation you can feel at the injection site -- not likely to be a discrete bubble.  Redness doesn't count -- you have to feel something.

Question 8

when you get a tb test and no bubble pops up does that mean its negative?

Accepted Answer

Yes: If there is no raised area which measures at least 5 mm in diameter the test should be considered negative.

Question 9

how long would it take for tb test marks to go away? mine came back neg but the mark went from unremarkable to large and red after 4 days now. thx.

Accepted Answer

TB Test: there can be several reasons why a TB test takes longer to reactt..If you do have a large reaction as you describe you should go back to your doctors office to show it to them as theymay decide it is a delayed positive test

Question 10

i got a tb test its itching and red. size of a quarter maybe but it doesn't seem to be swollen..pos? neg?

Accepted Answer

Allergy to ppd: Some people get a 'reaction' like that to a ppd-but it's not indicative of a positive TB test-instead it's an allergy to the material used for the test.  A doctor or trained professional can look at it and determine if it's positive based on 'firmness' (we call it induration) under the skin where the ppd was placed. Itchy and red skin is something else. If it's bad, some hydrocortisone cream helps
