Question 1

what's a two-step ppd test?

Accepted Answer

As it says: In some people with previous exposure to tb, especially remotely, an imitial TB skin test (tst) will be negative but a repeat, say 2 weeks later, can be positive.  It is sort of like waking up the immune recognition of the bug.  But, it is not at all clear that those who are only positive on the two-step tst are at risk for reactivation later as those with a 1-step positive tst.

Question 2

PPD: Negative test is flat not raised.Ay still be read. Should be interpreted by health care provider.

Question 3

what does a negative ppd test look like?

Accepted Answer

Question 4

please point me to where i can find my ppd record?

Accepted Answer

There is no: central repository for ppd records.  Try your primary care physician, and if you can recall where you had the ppd performed, call that facility.

Question 5

i just had a ppd test done and feel little bit unwell?

Accepted Answer

Unlikely from PPD: Never having seen systemic symptoms from placement of a PPD i cannot imagine how this "unwell" sensation might have occurred or if it is related to the ppd.  Perhaps a mild allergic reaction to the material in the ppd.  Hope you feel better soon.

Question 6

are there any dangers from repeating a potive ppd test?

Accepted Answer

Yes: The reaction the next time around can be more prominent leading to significant pain and discomfort and, potentially, a scar.  Once a person has had a positive PPD skin test, they should not have the test repeated.

Question 7

Accepted Answer

Unusual: But some people may develop malaise because of the thought of the test, or the immune reaction may precipitate some low grade symptoms, or there may be allergic reactions to material in the PPD preparation.

Question 8

what's the difference between a positive and negative ppd test?

Accepted Answer

PPD: Positive test: 5mm in HIV patients and other immunosuppressed individuals
all others: 10 mm .Measured induration after 48 hours.
Negative reaction: not exposed to tb.

Question 9

if i got a ppd shot in august 2011, how long are the results valid?

Accepted Answer

PPD: Ppd is a one or two step test for past exposure to tuberculosis.  Results are typically good for 1 year, however you only need them if someone requires you to have the test (school, work, etc.)  a positive test does not indicate you have an active TB infection, just that you have been exposed to the organism in the past.

Question 10

is there an effective way to determine if you are suffering from ppd?

Accepted Answer

PPDs don't hurt: Tuberculosis skin tests only heard if they're positive and very inflamed.  They may be red but a negative test for tuberculosis shouldn't hurt at all.  If the skin for the test was placed feels hard and uncomfortable you need more tests.
