According to the CDC, the QuantiFERON TB Gold test can be used in all cases that would typically require a TST. QuantiFERON Mitogen minus NIL: 71774-4: 2006963: QuantiFERON NIL: 71776-9: 3000401: Quantiferon TB Gold Plus: 71773-6: 3000402: Quantiferon Plus TB1 minus NIL: 64084-7: Mitogen - Nil: High, usually >10.0: This is a measure of the cell's ability to produce gamma interferon in response to non-specific mitogen stimulation. Some examples of live vaccines are varicella, MMR, yellow fever, and intranasal influenza. Incipient and subclinical tuberculosis: a clinical review of early stages and progression of infection. As compared to the normal mitogen response group, the negative response group were significantly more likely to have had surgery and an infection, or a severe infection within the 3 months preceding the QFT, and those with a weak response were significantly more likely to have had a severe infection in the 3 months preceding the QFT. Assessment of the accuracy of these tests is limited by lack of a standard for confirming LTBI. 0000001385 00000 n Several factors have been associated with indeterminate QFT results, including immunodeficiency, extreme ages and some chronic diseases (5, 610). For each case (either with negative or weak mitogen response), we included the control patient who had a QFT performed chronologically just after the corresponding case patient (Figure 1). Normal range/expected value(s) for a specific disease state. Huang C-T, Lee M-R, Ruan S-Y, Tsai Y-J, Wang J-Y, Yu C-J. In the context of culture-confirmed TB, QFT testing has been associated with negative sensitivity (70%) (26, 27). In addition, male sex, diabetes, and an infection within 3 months before QFT were independently associated with a negative mitogen response, but not with a weak mitogen response, as compared with a normal response (Model 1, Table 2). Is not affected by prior BCG (bacille Calmette-Gurin) vaccination. LabReqs.

Woo KS, Choi JL, Kim BR, Kim JE, Kim BG, Lee H, et al. 0000006042 00000 n In each final model, interactions between selected variables were systematically tested. Patients under the age of 18, patients only admitted for consultation (as outpatients), those hospitalized for less than 48 h, and those with incomplete QFT results were not included (Figure 1). <<022157bd818f5e479a168ae0d41e7b05>]>> The results are typically released within three to five business days. Clinical outcomes (onset of an acute infection, sepsis or septic shock after QFT sampling, ICU admission, in-hospital mortality and hospital length of stay) were also recorded. [6] Although there have been studies confirming the increased future risk of active TB in individuals with positive TST, the same was not true for those with a positive IGRA result. QuantiFERON-TB gold tests were performed by the same laboratory (virology laboratory of the Dijon University Hospital) according to manufacturer instructions. Two samples with indeterminate test results were due to high nil value (above 10 IU mL -1 ). Test Result Name. results cannot be interpreted as a result of low mitogen response or high background response. Specimen Requirements: . Correlation between INF- mitogen response of QFT and C-reactive protein levels was assessed in hospitalized patients included in the study and with available C-reactive protein data (n = 825); Spearman test. of Nil value Any . Written informed consent for participation was not required for this study in accordance with the national legislation and the institutional requirements. Royston P, Sauerbrei W. Building multivariable regression models with continuous covariates in clinical epidemiologywith an emphasis on fractional polynomials. Seeing that such a result is not a normal response to PHA stimulation, it may be thought to be a false negative QFT when diagnosing LTI, or even TB. Frequency and significance of indeterminate and borderline Quantiferon Gold TB IGRA results. As such, the CDC has advised that the QuantiFERON test be done either on the same day that the live vaccine is administered or a minimum of four weeks after. All had adequate mitogen responses including 105 (96.3%) with values of > 10 IU/mL, the others being 8.5 IU/mL, 8.03 IU/mL, 6.54 IU/mL and 3.28 IU/mL. The dysregulated innate immune response in severe COVID-19 pneumonia that could drive poorer outcome. In a study of military personnel returning from missions, about one-half of the positive TSTs were falsely positive. *Correspondence: Mathieu Blot, mathieu.blot@chu-dijon.fr, https://www.frontiersin.org/articles/10.3389/fmed.2022.876864/full#supplementary-material, Creative Commons Attribution License (CC BY).

Drain PK, Bajema KL, Dowdy D, Dheda K, Naidoo K, Schumacher SG, et al. If a patient underwent several QFTs during the study period, only the first was retained for the analysis. Careers - Clipboard, Search History, and several other advanced features are temporarily unavailable. LOINC code 71774-4 Mitogen stimulated gamma interferon [Units/volume] . Our results raise the question of whether a LTI can be confidently interpreted with a weak mitogen response. The second one, 5 weeks after the start of antimycobacterial treatment, was positive (Ag TB-Nil [IFN-] = 3.86 IU/mL).

Scheduled my appointment on line same day, I got vitamin B-12 injection,it was very fast ,everything took less than 15 minutes. The results are valid for all cases that would normally need a TB skin test. While QuantiFERON-TB gold (QFT) is frequently used, little attention is paid to the mitogen response. In order to provide a better understanding of indeterminate QFT, our aim was to assess the factors associated with mitogen response, including ongoing or recent infection. Among tuberculosis patients, a weak mitogen response was associated with a false-negative QFT result (75%) compared to a normal response (20%). At the time of the QFT sampling, an ongoing infection was detected in, respectively, 18, 33, and 48% of patients with a normal, weak and a negative mitogen response, respectively, and septic shock was detected in 1, 4, and 11%, respectively. Careers. Among these patients, 208 (8%) had a negative mitogen response (IFN- 0.5 IU/ml) and 228 (9%) had a weak mitogen response (IFN- = 0.52 IU/ml). %%EOF QuantiFERON-TB Gold Plus: Results and Interpretation When it comes to result calculation, qualitative cutoff values, and result interpretation, the QFT-Plus is identical to the QFT-Gold assay, with the key exception that if either one or both of the QFT-Plus TB antigen tubes are equal to or greater than 0.35 IU/mL and are at least 25% of the . . 0000004397 00000 n QuantiFERON-TB Gold (QFT) is a simple blood test that aids in the detection of Myc MJ, MB, and A-LS-L: recruitment of patients.

Among tuberculosis patients, a weak mitogen response was associated with a false-negative QFT result (75%) compared to a normal response (20%). Log-linearity was tested for each continuous variable using fractional polynomials (20). Tebruegge M, de Graaf H, Sukhtankar P, Elkington P, Marshall B, Schuster H, et al. J Infect Dis. 14. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The QuantiFERON TB Gold test was approved by the Food and Drug Administration in 2011 and functions as an alternative to a one-step or two-step TB Skin Test (TST). All variables associated with IFN- production with a p-value < 0.2 and at least 15 observations in each group were accounted for.

The device, as modified, will be marketed under the trade name quantiferon-tb gold in-tube and is indicated for use as an in vitro diagnostic test using a peptide cocktail simulating esat-6, cfp-10 and tb 7.7(p4) proteins to stimulate cells in heparinized whole blood drawn directly into specialized blood collection tubes. Outside the scope of TB, the weak mitogen response was independently associated with ongoing infections and could be associated with a worse prognosis. Quantiferon NIL: result 0.07 IU/mL. An individual is considered positive for M. tuberculosis infection if the IFN-gamma response to TB antigens is above the test cut-off (after subtracting the background IFN-gamma response in the negative control). an unexpectedly high rate of indeterminate IGRAs was noted in COVID-19-positive patients. The test result value may optionally contain a relational operator from the set {=, , >, >=}. The TB antigen and mitogen results of the QFT-GIT test and lymphocyte counts for the cases sub-divided into different co-morbid conditions are illustrated in Table 4. 0000016034 00000 n A low response to mitogen (<0.5 IU/mL) indicates an Indeterminate result when a blood sample also has a It does not distinguish between active and inactive tuberculosis.

If you are suspected to have TB and your doctor recommends that you undergo this test, keep in mind its advantages and limitations: After the blood sample is taken and analyzed, the QuantiFERON TB Gold test will render one of the following results: However, the QuantiFERON TB Gold test alone does not confirm the diagnosis of tuberculosis infection. Huang et al. Lange B, Vavra M, Kern WV, Wagner D. Indeterminate results of a tuberculosis-specific interferon- release assay in immunocompromised patients. When the variable a severe infection at the time of the QFT was added in the model instead of an ongoing infection at the time of QFT (model 4), this first was independently associated with a negative mitogen response (RR = 2.78; 95% CI [1.037.51]) (Supplementary Table 4 and Supplementary Figure 3). Disadvantages and limitations of the test are: On 10/10/2007 the US FDA[19] gave approval for the Quantiferon TB Gold In Tube to be marketed in the US.

Applies only to results expressed in units of measure originally reported by the performing laboratory. Infections are frequent in hospitalized patients, but our results suggest QFT should not be performed until after recovery. This well-known T-cell exhaustion phenotype (including quantitative and qualitative lymphocyte defects) is associated with worse outcomes during sepsis (14). . 13. Among tuberculosis patients . The nil tube value is subtracted from the values of the mitogen, TB1, and TB2 tubes for the final result of the respective tubes. QuantiFERON-Tb Gold Plus, B. There is need for further study of the utility of QFT in predicting the progression to active tuberculosis, particularly in children and immunocompromised hosts. J Investig Med. 2022511. Methods: [9] reported evidence suggesting false positive TST results are common and that QFT testing could guide more targeted treatment and alleviate unnecessary anti-tuberculous treatment. what is a normal mitogen level; change page title html. Am J Respir Crit Care Med. However, interestingly, we found that both recent and ongoing infection were independent factors associated with a negative mitogen response. Limited data on the use of QFT-G to determine who is at risk for developing TB disease. 0000002584 00000 n Indeterminate, which means that the test could not give a definitive negative or positive result. They are surrogate markers of Mycobacterium tuberculosis infection and indicate a cellular immune response to M. tuberculosis if the latter is present. The Nil tube measures circulating background interferon-gamma antibody, such as heterophile antibody. Correlation between INF- mitogen response of QFT and C-reactive protein levels was assessed in hospitalized patients included in the study and with available C-reactive protein data (, Clinical outcomes of 872 hospitalized patients according to the mitogen response of QFT (negative, weak or normal). The .gov means its official. Patients were categorized as immunocompromised if they were treated with an immunosuppressive or corticosteroid therapy (>0.15 mg/kg/day prednisone equivalent during more than 2 weeks or more than to 2 mg/kg per day within 3 months before QFT), or if they had active cancer or hematologic disorder, HIV infection, or primary immune deficiency. Tuberculosis, or TB, is a highly contagious and infectious airborne disease that affects the respiratory system, particularly the lungs. We recognize that technique may not be the only factor and we accept that mitogen values are currently not in a range that customers have previously observed. If the level of blood in any tube .
