A member asked:

What does it mean if i have a negative tb skin test yet a positive blood one?

A doctor has provided 1 answer

IMMUNE PROBLEM: Both tests detect prior exposure to TB. A situation of diminished immune function, called anergy, can make the skin test appear negative. If you have a positive blood test you will need to have a CXR to exclude active infection and may need prophylaxis .
