How to determine if someone has TB?
For many years, the best way to determine if someone may have an active tuberculosis infection was to use a skin test.

The QuantiFERON-TB Gold blood test takes some of the guesswork out of the tuberculosis screening process.
What does a negative test mean?

This means that the sample can be centrifuged (spun) in the lab and the separated serum easily removed.
