Accepted Answer

About PPD tests: A PPD skin test reaction is read between 48 and 72 hours after administration. The reaction should be measured in millimeters. The part that is measured is the induration (palpable, raised, firm area or swelling). If there is no raised skin that one can FEEL without looking at it, then there is nothing to measure (the result gets written as 0 mm). Each patient's situational details also matter.

Question 2

what does negative ppd result look like?

Accepted Answer

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

See below: A positive PPD is determined by the presence of swelling(induration) around the injection site.  Little or no swelling indicates a negative test.  Reddness is not used to determine a neg or pos test.

Question 4

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 5

online site with photos of negative ppd results?

Accepted Answer

Not necessary: A negative PPD simply means you don't have a lump at the site of the PPD injection 48-72 prior.  This means the skin appears normal. If there is a raised bump at the site, then depending on your particular risk factors or history, you may be positive.  The next step would be a chest x-ray.  But, if no bump, then negative.

Question 6

is it possible to have tb after a negative ppd test?

Accepted Answer

PPD testing: The answer is yes. A previous exposure to TB (travel to a country where TB is endemic) can result with a negative PPD test before the germs produce disease. Have yourself retested in 8 to 10 weeks if still suspicious or opt for the blood test, quantiferon.

Question 7

had a ppd skin test and the result is 10 mm the reference says 5 to 10 is borderline. and i don't get it what they mean and what to do next ?

Accepted Answer

See details: A 10 mm test is a positive result. Ask your doctor to order a Quantiferon Gold TB blood test. If this test is positive, you have been exposed to TB.

Question 8

ppd skin test, negative, no reaction and swelling (72 hrs). the test was taken in last tuesday morning, 9am, now it gets swelling and itch. positive?

Accepted Answer

Delayed onset ppd: This could represent a positive reaction. Their is a besst confirmatory test called a quantiferon-gold test which is a gamma-interferon release assay for tb. It has some limitations but if positive is very accurate for diagnosis, ask an infectious disease specialist about this if your pcp does not know about this test.

Question 9

just had a ppd test done is it normal after my test results came back i have a rash like bump on my arm?

Accepted Answer

Positive: That could be a positive test.  Otherwise that will go away in a few days

Question 10

help!! whats wrong with me? got a ppd test done came back positive, got xray and blood test done came back negative for tb and negative for stds. what other than std or tb can cause positive test ? can anyone give a detailed answer?

Accepted Answer

: A PPD skin test is falsely positive up to ~2% of the time. Common causes include misinterpretation, BCG vaccine as an infant (not done in the US) and infection my non-TB members of the mycobacteria family which are often minor. This is a relatively cheep screening tool, compared to the IGRA blood test that is more accurate. The testing you had says you are fine. I wouldn't worry about it.
