Tuburculosis! HELP.
Get a second test from a different provider, just to be certain! My friend got a test that was improperly administered and it came back false positive. Lucky for her, she is a nurse and noticed that the person administering the test didn't insert the needle at the correct depth and angle, so she requested a second test administered correctly. The second test came back negative.
Don't freak...LOTS of people test positive for the skin tests. I test positive. I give and read TB skin tests and many people test positive. They get the x-ray, it's clear, and all is good. SOME employers also require a blood test called quatiferon gold test. But that's no biggie either. Since you're not working in health care, the x-ray should suffice without the blood test.
