QuantiFERON-TB Gold Plus, 1 Tube details
What QuantiFERON-TB Gold Plus, 1 Tube shows
The QuantiFERON®-TB Gold Plus test is a blood-based alternative to the traditional tuberculin skin test (PPD/Mantoux test) used to check whether your immune system has been exposed to tuberculosis (TB) bacteria at some point. It works by exposing a blood sample to TB-specific proteins and measuring your immune cells' response; unlike the skin test, it isn't affected by prior BCG vaccination (common in some countries) and only requires one visit, since there's no need to return in 48-72 hours to have a skin reaction read. A positive result indicates TB exposure (latent or active infection) but doesn't by itself distinguish between the two, which requires further clinical evaluation, including imaging and symptom assessment.
Tests that include QuantiFERON-TB Gold Plus, 1 Tube
QuantiFERON-TB Gold Plus is an indirect test for M. tuberculosis infection. It is intended to be used in conjunction with risk assessment, radiography, and other medical and diagnostic evaluations.
- Mitogen-NiL A control value in the QuantiFERON-TB Gold Plus test showing that your immune cells can respond normally, so the TB result can be trusted.
- QuantiFERON Nil Control A baseline (no-stimulation) control value used in specialized immune function tests, such as TB or allergy blood testing, to interpret the other results correctly.
- QuantiFERON-TB Gold Plus, 1 Tube A blood test that checks whether your immune system has been exposed to tuberculosis, as an alternative to the traditional skin (PPD) test.
- QuantiFERON TB1 Antigen Minus Nil The TB1 antigen tube result minus the nil (background) tube in the QuantiFERON-TB Gold Plus test, reflecting a T-cell response to tuberculosis proteins.
- QuantiFERON TB2 Antigen Minus Nil The TB2 antigen tube result minus the nil (background) tube in the QuantiFERON-TB Gold Plus test, reflecting CD4 and CD8 T-cell responses to tuberculosis.
