A healthcare worker will interpret your test results by looking at the injection site on your forearm at 48 or 72 hours (in most cases). A positive result will form a red and swollen circle at the site of the injection. The size (diameter) of the swollen raised circle determines whether exposure to TB has occurred. The size that is considered positive varies with the health status and age of the individual. Even when infected, children, the elderly, and patients who are severely immune compromised (such as those with AIDS) may have smaller, delayed, or even negative reactions to the TB skin test.
Negative results may mean that you have not been exposed to TB, that your immune system has not responded to the test, or that it is too early to detect exposure. It takes about 6 weeks after infection before a person demonstrates a positive reaction to the PPD. If your doctor wants to confirm a negative result, he may repeat the TB skin test, or in some cases, perform another type of test called QuantiFERON® - TB Gold test (QFT-G).

Positive results may be due to a latent or active TB infection, or occasionally due to a false positive. Positive results may also be seen in those who have received a BCG (Bacille Calmette-Guérin) vaccination. BCG is a vaccine that is not used in the United States but is often routinely administered in other countries that have a higher incidence of TB.

Positive results must be followed up by other tests such as chest X-rays to look for signs of active TB disease. If active TB disease is suspected, AFB cultures may be used to confirm the diagnosis.

Its not checked by color just by size! If it gets big then u have it! If its normal u dont! They just did it to my cousin a couple of days ago and it was red but it never got big so its nothing! If it does get big then get a doctor!
 
the only thing they check to see if it's negative/positive is the size of the little bubble. if it's gone after 2 days, you're fine. if it's still there, they measure the size of it and if it's small, you're fine also (it's negative). color shouldn't have anything to do with it :)
 
It's ok for it to be red, so don't worry just because it's red...it's supposed to be a bit red HOWEVER if it tarts bubbling up that's when you worry...If it's a tiny bubble that comes up after a while or if it looks irritated or like an allergy then call your doctor but normally you have to go see them in a couple of days so jut wait it out.
You'll be fine....even if you get a reaction, it's not strong enough to make you sick, just give you a small irritation and the doctor will tell you what to do when you back to see him, or the nurse that gave you the shot...Leave the area alone, don't touch it..Don't scratch it, and when you shower don't rub it too hard.
This can irritate the area a little bit and give a false reading then you'll have to get another shot..
Just leave it alone for a while, then go back in 2 or 3 days to have the nurse or doctor check it....You'll be fine though...Good luck!
