my MD ordered this test. why? i am a healthcare worker and i get tested yearly with the TB skin test and have tested negative, so why this test? does it detect something that the skin test doesn't. thanks
Response from Dr. Holodniy
It tests the same thing, although using a blood test and not a skin test. Some people believe it may be more sensitive in determining PPD status than a skin test.
