The NIL value represents nonspecific reactivity produced by the patient specimen. . QuantiFERON-TB (Cellestis) Originally developed in Australia to test cattle for M. bovis infection Measures IFN- in stimulated whole blood relative to a nil and mitogen control 1. The QuantiFERON-TB Gold In-Tube test (QFT-G-IT) was indeterminate with a mitogen-minus-nil interferon-gamma (IFN-) value of 0.22 IU/mL. The association between borderline results and incident active TB within 3 to 24 months was investigated through linkage with the national TB-register.

His upper limbs on patient and provider preference uses the same principle, procedures. Mitogenesis is the induction (triggering) of mitosis, typically via a mitogen. Device Trade Name: LIAISON QuantiFERON-TB Gold Plus, . Bethesda, MD 20894, Web Policies A low response to Mitogen (less than 0.5 IU/mL) will produce an Indeterminate result. The centrosome is an organelle that is found in a specific region of the cell near the nuclear membrane. The CDC recommends that IGRA tests such as QFT-Plus are the preferred test to use for persons who have received Bacillus Calmette-Guerin (BCG) as a vaccine or for cancer therapy. FOIA *For a test to be considered positive, the TB antigen tube value minus the Nil tube value must be 0.35 IU/mL (FDA cleared breakpoint). Normal Reports | Abnormal Reports. Low positive values (0.35-1.0 IU/mL) may not repeat as positive in some patient populations; some authorities recommend that the patient be retested to confirm low positive tests. A low response to Mitogen (<0.5 IU/mL) indicates an Indeterminate result when a blood sample. This low Mitogen response is most often associated with reduced lymphocyte activity due to: low numbers of lymphocytes or Interquartile range [ quantiferon mitogen minus nil normal range ] 0.9-10.7 ) in those with having positive test results there C for 16 to 24 hours positive QFT-GIT, 59 ( 5.7 % ) were due to low response. Key for results: AB abnormal H high etc. Blue line: Patients with very low IFN- response to PHA (IFN- concentration (minus nil) in mitogen tube < = 604.2; range: 398-842). Depending on the strength of the immune response, a medical provider can determine if there is the possibility of an infection. . The cut-off value for positive finding (TB antigen minus nil) was 0.35 kIUl-1 and by 25 % higher than the nil value. My calculated value of 1.06 (TB antigen tube value minus the Nil tube value) can show a 52% reversion rate. In some people, an inconclusive result may occasionally occur. For safety reasons, this is best performed by removing the syringe needle, ensuring appropriate safety procedures, removing the caps from the 4 QFT - Plus Blood Collection Tubes and adding 1 mL of blood to each (to the black mark on the side of the tube label which indicates the validated range of 0.8 - 1.2 mL). . Nil tube. Red cell distribution width is a clinical measure that is used to assess the size of the red blood cells or calculate the volume of the red blood cells. By binding to these moieties, lectins often agglutinate several cells together. There are two currently approved TB blood tests that are on the market right now in the United States: the QuantiFERON TB Gold test and the T-SPOT TB test.

The QuantiFERON-TB Gold In-Tube test (QFT-G-IT) was indeterminate with a mitogen-minus-nil interferon-gamma (IFN-) value of 0.22 IU/mL. Consideration of these values may be of interpretive value in the event of an Indeterminate result. The mitogen stimulated plasma sample serves as an IFN- positive control for each specime. A mitogen is a peptide or small protein that induces a cell to begin cell division: mitosis. Mitogen-Nil The maximum non-specific stimulated interferon- gamma level that may be produced by the patient's lymphocytes minus the Nil (i.e., basal) level of interferon-gamma. (mitogen -- nil) and (tuberculin -- nil) are both > 1.5 IU; and percentage avian difference < 10; and percentage tuberculin response > 15 (increased risk for LTBI) or > 30 (low risk for LTBI). A diagnosis of LTBI requires that TB disease be excluded by medical evaluation, which should include checking for signs and symptoms suggestive of TB disease, a chest radiograph, and, when indicated, examination of sputum or other clinical samples for the Hug. . 2012;142(1):6375.
