Quantiferon (TB)

Nov 5, 2006

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.
