It is generally recommended to results where Nil > 8.0 IU/ml (high background) consider . Errors in collecting or transporting blood specimens or in running and interpreting the assay can decrease the accuracy of QFT-G. QuantiFERON, also known as QFT, is the registered trademark of an interferon gamma release assay (IGRA) for tuberculosis diagnosis manufactured by QIAGEN. Proportion of patients with infectious complications during hospital stay after QFT sampling (A), intensive care unit (ICU) admissions (B), in-hospital mortality (C) and the median (interquartile range) hospital length of stay (D) were recorded and represented according to the mitogen response: negative (IFN- 0.5 IU/ml), weak (IFN- = 0.52 IU/ml) and normal (IFN- > 2 IU/ml). Clin Chim Acta 2014;430:79-83. Mitogen Control, TB Antigen) Minimum Volume: 1.0 ml required per tube; Fill tubes to the black line on the side of the tube label = 1.0 ml. Results can be available within 24 hours. Background Interferon gamma release assays (IGRAs) are the first new diagnostic tests for latent tuberculosis (TB) infection (LTBI) since the century-old tuberculin skin test (TST). Among tuberculosis patients, a weak mitogen response was associated with a false-negative QFT result (75%) compared to a normal response (20%). Table 1. Careers - A teszt rzkeny a Mycobacterium tuberculosis, bovis, caprae s africanum trzsekre. This is because everyone's immune systems are different.

The negative and weak mitogen response groups were younger (p < 0.001 for both) than normal response group and less frequently immunocompromised (p < 0.001 for both). Divangahi M, Aaby P, Khader SA, Barreiro LB, Bekkering S, Chavakis T, et al. TB is a severe illness with fatal consequences. According to the FDA approved package insert[20] Quantiferon TB Gold In Tube has a consistent specificity of >99% in low risk individuals and a sensitivity as high as 92% in individuals with active disease, depending on setting and extent of disease. 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). Tuberculosis, or TB, is a highly contagious and infectious airborne disease that affects the respiratory system, particularly the lungs. 3. MJ, MB, A-KS, CB, and LP: acquisition, analysis, or interpretation of data. Inverse correlation between INF- mitogen response and C-reactive protein levels in hospitalized patients. TST and QFT do not measure the same components of the immunologic response and are not interchangeable. It spreads from one person to another via tiny water droplets which are excreted into the air when an infected person coughs or sneezes. Interpretation of QFT results is stratified by estimated risk for infection with M. tuberculosis, in a manner similar to that used for interpreting TST with different cut-off values. Concurrent immune suppression and hyperinflammation in patients with community-acquired pneumonia. sharing sensitive information, make sure youre on a federal Retrospective, case-control study in hospitalized patients who underwent QFT testing in two hospitals between 2016 and 2019. One quarter of the world population is potentially affected by a latent tuberculosis infection (LTI) (1). 0000010668 00000 n It's not recommended for children who are under five years old (under two years old for immigration requirements). The QuantiFERON-TB Gold test (QFT-G) is a whole-blood test for use as an aid in diagnosing Mycobacterium tuberculosis infection, including latent tuberculosis infection (LTBI) and tuberculosis (TB) disease. LOINC. On 25 June 2010, the US Centers for Disease Control and Prevention (CDC) updated the tuberculosis (TB) testing guidelines providing guidance to US public health officials, clinicians, and laboratory workers regarding screening for and diagnosis of TB infection. However, there is a possibility that the bacteria can become active, so it's still crucial for someone with latent TB to seek guidance from a medical provider. quantiferon mitogen value normal range. Would you like email updates of new search results? Comparisons were made between the 3 groups using Kruskall-Wallis test for continuous variable, and the Chi-square test for qualitative variables. It can be assumed that lymphopenia and T-cell exhaustion, which are frequent in TB (17), explain this lack of sensitivity in connection to an altered mitogen response. Brands X, Haak BW, Klarenbeek AM, Otto NA, Faber DR, Lutter R, et al. 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. Methods We reviewed all patients, regardless of COVID status, who were admitted between March 1, 2020, and . In conclusion, it appears to be of utmost interest to consider the mitogen response in hospitalized patients who undergo QFT, in particular when this response is negative or weak (IFN- 2 IU/mL). Interpretation of the QuantiFERON TB Gold Test Results. Let's dive into the pros and cons and result interpretations of the QuantiFERON TB Gold test, as well as more information on tuberculosis. Data were collected from the 3 groups of patients constituted, namely the cases (all the patients with a negative or a weak mitogen response) and the control patients (1 control patient/case with a normal mitogen response). Finally, in hospitalized patients who underwent a QFT, we observed that weaker IFN- production was associated with a worse prognosis, considering infectious complications, ICU admission, in-hospital mortality, and hospital length of stay. According to the U.S. Centers for Disease Control,[2] in 2001, the QuantiFERON-TB test (QFT) was approved by the Food and Drug Administration (FDA) as an aid for detecting latent Mycobacterium tuberculosis infection. In addition, sex, immunodepression and higher platelets were independently associated with a negative mitogen response, and diabetes was associated with a weak mitogen response when compared to the normal mitogen response group (Supplementary Table 3 and Supplementary Figure 2). Positive (>0.99 IU/ml) 6712: 65: Total number of cases: 40773: 96: What is a normal QuantiFERON mitogen value? National Library of Medicine 0000017048 00000 n [citation needed], Compared with TST, QFT results are less subject to reader bias and error. May also include abnormal ranges. QIAGEN Inc.

We observed that patients with negative and weak mitogen responses have similar characteristics, especially for immunodepression status, which was identified in, respectively, 58 and 52% of these patients, compared with 36% of patients with normal response. n tested. (2014) 58:320-4. Epub 2019 Oct 3. Third, the cutoff we used to define weak mitogen response is rather arbitrary, and whether higher thresholds would be associated with different parameters and outcomes was not assessed. The https:// ensures that you are connecting to the However, interestingly, we found that both recent and ongoing infection were independent factors associated with a negative mitogen response. I was so amazed with their customer service. 0000015185 00000 n MJ, MB, CB, and LP: concept and design. The exhaustion of T lymphocytes is a well-known consequence of sepsis (23) and other chronic infections such as TB (17, 24), minimizing the damage to host tissue related to inflammatory response (25). Mitogen or Positive Control Tube A test is considered positive for an IFN- response to the TB Antigen tube that is significantly above the Nil IFN- IU/mL value. 0000008330 00000 n 0000002143 00000 n Because IGRAs are not affected by Bacille CalmetteGurin (BCG) vaccination status, IGRAs are useful for evaluation of LTBI in BCG-vaccinated individuals, particularly in settings where BCG vaccination is administered after infancy or multiple (booster) BCG vaccinations are given. In contrast, the specificity of tuberculin skin test (TST) varies depending on timing of BCG and whether repeated (booster) vaccinations are given. QuantiFERON-TB Gold PLUS (4 tube assay). Dorman SE, Belknap R, Graviss EA, Reves R, Schluger N, Weinfurter P, et al. government site. In suspected TB, aside from the response to the TB antigen, it suggests the need for further testing to avoid premature interpretation and misdiagnosis. However, as with a TST, there is a possibility that live vaccines might affect the test results of the QuantiFERON TB Gold test. The black mark on the side of the BCTs indicates the validated range of 0.8 to 1.2 ml. The QuantiFERON-TB Gold blood test takes some of the guesswork out of the tuberculosis screening process. 89108, Plan ahead; Children not being seen as a patient are not permitted in the exam room or unaccompanied in the lobby, Copyright 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). Results are expressed as relative risks (RR) and 95% confidence intervals (CI). (2020) 11:1364. doi: 10.3389/fimmu.2020.01364. QFT4. 0000002363 00000 n mL1 [2].

Frequency and significance of indeterminate and borderline Quantiferon Gold TB IGRA results. These values do not apply to results that are converted to other units of measure. In addition, the clinical relevance of the standard 0.5 IU/mL threshold is a matter of debate, and it has been suggested that a response to PHA with IFN- < 10 IU/mL could be considered possibly altered rather than normal (18). Factors related to COVID-19 severity, such as higher lactate dehydrogenase (LDH) (odds ratio [OR] 1.005 [95% condence interval [CI] 1.002-1.008]) and previous administration of corticosteroids (OR 4.477 [95% CI 1.397-14.345]), were independent predictors for indeterminate QFT-Plus assay.

QuantiFERON TB Gold test is a basic blood test that helps in the detection of the Mycobacterium tuberculosis which is responsible for causing tuberculosis. 19. Decreasing mitogen response (normal, weak and negative, respectively) was associated with increasing length of hospital stay (median (interquartile range) 5 (3-13), 11 (5-21) and 15 (10-30) days; p<0. . (2020) 18:457. Decreasing mitogen response (normal, weak and negative, respectively) was associated with increasing length of hospital stay [median (interquartile range) 5 (313), 11 (521) and 15 (1030) days; p < 0.001] and increasing hospital mortality (3, 7, and 15%; p < 0.001). Among the 872 patients included, 18 patients (2%) had microbiologically confirmed TB, among whom 6 (33%) had a false negative QFT [2/10 (20%) with a normal mitogen response, 3/4 (75%) with a weak and 1/4 (25%) with a negative mitogen response (Supplementary Table 6)]. There is limited data on the use of QFT-G in children younger than 17 years of age, among persons recently exposed to. Moreover, IGRA was at least as sensitive and was more specific compared to traditional TST. Cell Mediated Immune Response. . QFT was less frequently positive if mitogen response was weak (25% of cases) compared to normal (80% of cases). Name Value Reference Range NIL 0.040 UI/mL MITOGEN-NIL 10.065 IU/mL TB Ag-NIL 0.479 IU/mL INTERFERON GAMMA RESULTS POSITIVE NEGATIVE. . Third, among confirmed TB patients, a weak mitogen response was associated with false negative QFT results. It is an immune response-based, indirect test for M tuberculosis infection (including disease) and is intended for use in conjunction with risk assessment, radiography, and other medical and diagnostic evaluations. Mitogen is a very insensitive marker, and only mitogen is slightly . Scheduled my appointment on line same day, I got vitamin B-12 injection,it was very fast ,everything took less than 15 minutes. Since IGRAs are more costly and technically complex to do than the Mantoux test, in their 2011 policy statement, the WHO did not recommend replacing the Mantoux test by IGRAs as a public health intervention in low- and middle-income countries.[1]. quantiferon mitogen minus nil normal range. 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). However, the association between infection and negative mitogen response among patients tested for a suspicion of LTI or tuberculosis (TB) has not yet been addressed. First, the presence of an ongoing infection at the time of QFT was independently associated with a negative mitogen response and therefore indeterminate QFT results. When the severe infection at the time of the QFT variable was added in the model instead of the an ongoing infection at the time of QFT variable (model 2), the first variable was independently associated with both a negative (RR = 20.09; 95% CI = 8.6946.46) and a weak (RR = 7.10; 95% CI = 2.9317.23) mitogen response (Supplementary Table 2). In our study, the statistically derived cut-off value of QFT-Plus used for the accuracy analysis was 0.168 IU/mL, which is much lower than the currently recommended value of 0.35 IU/mL; thus, the . - by Casenaz A, Grosjean S, Aho-Gll LS, Bour JB, Auvray C, Manoha C. Front Med (Lausanne). More automation will be needed to accurately measure the QFT response. Crit Rev Microbiol. 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. 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. Ferrara G, Losi M, Meacci M, Meccugni B, Piro R, Roversi P, et al. TB, when it isn't treated right away, can become a fatal disease. HHS Vulnerability Disclosure, Help Acute infections observed at the time of QFT sampling were mainly bacterial (85%) and of pulmonary origin (56%) (Supplementary Table 1). Conclusion: Clinicians should take notice of the mitogen response since IFN- concentrations lower than <2 IU/ml were associated with false-negative QFT results in tuberculosis patients, independently associated with ongoing infections, and could be associated with worse prognosis. Clin Microbiol Rev. 0000006042 00000 n Continuous variables were expressed as means standard deviation (SD) or medians and inter-quartile range (IQR), according to distribution, and categorical variables were expressed as frequencies and percentages.

This value was corrected for the Nil response using QuantiFERON software, which calculates mitogen minus Nil values. Second, patients with a weak mitogen response and negative mitogen response had several similarities. (2014) 189:77-87. doi: 10.1164/rccm.201302-0365OC, 10. (2018) 31:e2118. If the patient is infected with M. tuberculosis, their white blood cells will release IFN-gamma in response to contact with the TB antigens. The nil tube value is subtracted from the values of the mitogen, TB1, and TB2 tubes for the final result of the respective tubes. Approval for a modification of the quantiferon-tb gold to an in-tube collection system that consists of three blood collection tubes, nil, tb antigen, and mitogen. Clinicians should take notice of the mitogen response since IFN- concentrations lower than <2 IU/ml were associated with false-negative QFT results in tuberculosis patients, independently associated with ongoing infections, and could be associated with worse prognosis. Mitogen minus Nil [IU/mL] QuantiFERON-TB Plus Result Reporting; 8.0: 0.35 and 25% of Nil value: Any: Any: Positive: POC: Any: 0.35 and 25% of Nil value: POC . The presence of an active infection within the last 3 months or at the time of the QFT sampling were recorded if the infection was clinically/biologically suspected or confirmed by the clinician in charge of the patient. Infections, and particularly severe sepsis, are associated with both lymphopenia and functional lymphocyte defects (T-cell exhaustion or anergy), which resolve at least partially about 1 month after sepsis (21, 22). QuantiFERON tubes fill slowly hold the tube on the needle for 2-3 seconds after flow ceases. Significance of the TB Antigen Results: QuantiFERON-TB Gold Plus (QFT-Plus) is a 4th generation in vitro diagnostic test using a peptide cocktail with ESAT-6 and CFP-10 proteins to stimulate cells, particularly T lymphocytes . An ongoing infection was independently associated with both a negative (RR = 4.34; 95% CI = 2.946.41) and a weak mitogen response (RR = 2.44; 95% CI = 1.663.58).
