QuantiFERON Nil Control details
What QuantiFERON Nil Control shows
The 'nil' value is a baseline control result used in certain specialized blood tests, such as TB blood tests (QuantiFERON®-TB) or specific allergy testing, representing the result with no stimulating antigen added. It's used as a reference point to properly interpret the other values in the same test — for example, confirming that a positive-looking result in the stimulated samples is a real response above baseline, rather than a false signal, and that the nil value itself isn't unexpectedly high, which could suggest a lab or sample handling issue.
Tests that include QuantiFERON Nil Control
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.
