QuantiFERON TB2 Antigen Minus Nil details
What QuantiFERON TB2 Antigen Minus Nil shows
QuantiFERON®-TB Gold Plus checks for immune memory of tuberculosis (TB) bacteria by mixing your blood with TB proteins and measuring interferon-gamma released by your T cells. TB2-NiL is the result from the TB2 tube, which is designed to stimulate both CD4 helper and CD8 cytotoxic T cells, after subtracting the nil tube that shows your background level. A raised value suggests your immune system has been exposed to TB bacteria. The test cannot separate latent infection from active disease, and a low value does not rule out infection. The final result is interpreted using all tubes together with your history and other tests.
Tests that include QuantiFERON TB2 Antigen Minus Nil
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.
