The test involves taking a blood sample, which will then be sent to a laboratory for analysis.

Unlike the TB skin test, which involves injecting a substance into the skin and checking for a reaction 48 to 72 hours later, the Quantiferon test requires only one patient visit and gives results within 24 to 48 hours. It's also less likely to give false-positive results due to BCG vaccination.
