Factors influencing discordant results of the QuantiFERON-TB Gold In-tube test in patients with active TB. Absolutely appreciate Brenda at Rainbow location for helping me get my appointment with Leah. If it is decided that you should have preventative medication, the usual treatment is antibiotic . Mitogen is a very insensitive marker, and only mitogen is slightly . The first test at the time of TB diagnosis (pulmonary and peritoneal involvement) was considered negative (Ag TB-Nil [IFN-] = 0.05 IU/mL), while the mitogen response was weak (mitogen [IFN-] = 1.03 IU/mL). A confirmatory test based on QuantiFERON technology was developed in which mitogen tubes were filled with 1 mL of whole blood from a healthy donor to which 100 L (1:10 dilution) or 20 L (1:50 dilution) of NTM patient serum . 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. The result of the test is a numeric value that relates to a continuous numeric scale. Belliere J, Blancher A. QuantiFERON test interpretation in patients receiving immunosuppressive agents: an alert. When considering only clinical variables, multivariable analysis revealed that an ongoing infection at the time of QFT was independently associated with both a negative (negative vs. normal RR = 4.34; 95% CI = 2.946.41), and a weak mitogen response (weak vs. normal RR = 2.44; 95% CI = 1.663.58), as well as older age and immunodepression. QFT4. 0000035516 00000 n an unexpectedly high rate of indeterminate IGRAs was noted in COVID-19-positive patients. While most of the identified factors are related to chronic conditions, little attention has been paid to the factors potentially associated with acute conditions at the time of QFT sampling. quantiferon mitogen value normal range.

(2018) 31:e2118. Clinical evaluation and additional tests (such as a chest radiograph, sputum smear, and culture) are needed to differentiate between a diagnosis of latent TB or active TB. In addition, in the patient who underwent serial QFT, there was a correction of both mitogen and TB antigen responses between TB diagnosis and 5 weeks later under treatment. NB: IFN-, interferon , QFT, QuantiFERON-TB Gold. (2018) 31:e2118. [11] Research at Stanford University and the Veterans Administration has reported the use of a retesting (or borderline) zone below 1.1 IU/ml mitigates 76% of the false-positives, or reversions.

MJ, MB, and CB: drafting of the manuscript. Specimen Requirements: . Outside the scope of TB, the weak mitogen response was independently associated with ongoing infections and could be associated with a worse prognosis. 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. This positive result was associated with an improved mitogen response (mitogen [IFN-] > 10 IU/mL), decreased C-reactive protein levels, and no change in the lymphocyte count (Supplementary Figure 4). 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. endstream endobj 23 0 obj<>stream 0000008330 00000 n Interferon-gamma release assays (IGRAs) are diagnostic tools for latent tuberculosis infection (LTBI). When considering both clinical and biological variables (model 3), multivariable analysis revealed that lower serum albumin, hemoglobin and lymphocytes, but higher neutrophil counts were independently associated with both a negative and weak mitogen responses (vs. normal). 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). The lower and upper limits of agreement (mean difference 1.96 SD) were the greatest in the mitogen response with values of 7.1 IU/ml and + 6.6 IU/ml. After the blood sample is taken and analyzed, the QuantiFERON TB Gold test will render one of the following results: Negative or Normal. Fourth, the mitogen response was associated with hospital length of stay and in-hospital mortality. 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. Blot M, Bour J-B, Quenot JP, Bourredjem A, Nguyen M, Guy J, et al. According to the World Health Organization, it caused approximately 1.5 million deaths in 2020. Latent TB is when you are infected with tuberculosis, but you are not exhibiting any symptoms because the bacteria residing in your body is inactive. Range of Values: 1581: 1581. These values do not apply to results that are converted to other units of measure. Assessment of the accuracy of these tests is limited by lack of a standard for confirming LTBI.

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. . Bookshelf However, our study is novel in that it is the first study to observe an association between mitogen response and clinical outcomes in hospitalized patients. This well-known T-cell exhaustion phenotype (including quantitative and qualitative lymphocyte defects) is associated with worse outcomes during sepsis (14). In our study, 8% of hospitalized patients had indeterminate QFT results, which is in the range of other previously published studies (5). Variability, a big issue that influences the result adversely. Pourakbari B, Mamishi S, Benvari S, Mahmoudi S. Adv Med Sci. 0000002219 00000 n %PDF-1.5 % Not sure of the spelling of her name. Some can appear more, or less, sick than others. In the United States, the test is widely available from state public health laboratories, hospitals, and commercial laboratories. 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. As with most medical processes, the QuantiFERON TB Gold test has its pros and cons. It can also infect other parts of the body such as the bones, brain, eyes, and lymph nodes. 0000001563 00000 n Requires a single patient visit to draw a blood sample. Is blood lymphocyte count a prognostic biomarker in Staphylococcus aureus bacteremia? This value was corrected for the Nil response using QuantiFERON software, which calculates mitogen minus Nil values. The mitogen tube must demonstrate an interferon- value of 0.5 IU/ml higher than the value of the NIL tube. In this study of immunocompetent recently exposed close contacts of active TB cases, the progression rate to active disease among untreated QFT positive individuals was significantly greater than for untreated TST positives (14.6% versus 2.3%). Average price range of the test is between Rs.2400 to Rs.5490 depending on the factors of city, quality and availablity. Avoid at all costs if you are going to do an immigration medical exam. Posted: Feb 22nd, 2022 at 04:14PM Some examples of live vaccines are varicella, MMR, yellow fever, and intranasal influenza. The negative and weak mitogen response groups were not significantly different for these two variables. Multivariable analyses identified age, immunodepression, serum albumin, hemoglobin, and neutrophil and lymphocyte counts as factors associated with a negative mitogen response, as previously reported (3, 7). 25. This page was last edited on 20 February 2023, at 09:25. value. I fly out of the county alot and e7Health is always flying with me! This is because everyone's immune systems are different. Acute infections observed at the time of QFT sampling were mainly bacterial (85%) and of pulmonary origin (56%) (Supplementary Table 1). Let's dive into the pros and cons and result interpretations of the QuantiFERON TB Gold test, as well as more information on tuberculosis. 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. Septic shock as sepsis with persisting hypotension requiring vasopressors to maintain mean arterial pressure 65 mm Hg and had a serum lactate level >2 mmol/L (18 mg/dL) despite adequate volume resuscitation (19). 2011;6(6):e20061.

I figure if I tested positive for tb it'd be on the . above the Nil IFN- IU . 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. FOIA We conducted a retrospective, observational, case-control study in a cohort of patients hospitalized for at least 48 h in two healthcare facilities [Dijon University hospital and the Georges Franois Leclerc cancer (CGFL) center] between October 1, 2016 and October 31, 2019, and who underwent QFT testing during hospitalization. Comparisons were made between the three groups using KruskalWallis tests or ANOVA when appropriate for continuous variables, and the Chi-square test for qualitative variables. We can assume that confirmed TB cases with extensive diseases and/or those with systemic involvement were associated with both systemic inflammation and T-cell exhaustion. Best.

Detection of interferon-y by enzyme-linked immunosorbent assay (elisa) is used to identify in vitro responses to these peptide antigens that are associated with mycobacterium tuberculosis infection. The site is secure. Finally, 872 patients were included in the study (Supplementary Figure 1). -. You must tell your doctor what medicine you are taking, your medical history and if you are pregnant or breastfeeding. 2023 e7 Health - 11 38 In a study of military personnel returning from missions, about one-half of the positive TSTs were falsely positive. 0000015259 00000 n Active TB, on the other hand, is when you are infected with the bacteria and show symptoms of the illness. 0 Moreover, IGRA was at least as sensitive and was more specific compared to traditional TST. [8] In a more recent study of military returning from missions, Franken et al. One milliliter of whole blood was incubated for 1624 h at 37C, after which plasma was harvested and tested using an enzyme-linked immunosorbent assay for the presence of IFN- produced in response to the peptide antigens or PHA (mitogen). 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). Surviving sepsis campaign: international guidelines for management of sepsis and septic shock: 2016. Programmed death-1 levels correlate with increased mortality, nosocomial infection and immune dysfunctions in septic shock patients. Our results raise the question of whether a LTI can be confidently interpreted with a weak mitogen response. (2017) 43:304-77. (2020) 11:796. doi: 10.3389/fimmu.2020.00796. Depressed T-cell interferon-gamma responses in pulmonary tuberculosis: analysis of underlying mechanisms and modulation with therapy. Tuberculosis (TB) was recorded if there were associated clinical-radiological signs of TB and it was confirmed with laboratory testing (Mycobacterium tuberculosis identification with culture and/or polymerase chain reaction). We defined two groups of cases with either negative [interferon (IFN)- 0.5 IU/ml, official threshold] or weak (0.52 IU/ml) mitogen response, and one group of controls with normal (>2 IU/ml) mitogen response. The test is based on the quantification of interferon-gamma (IFN-) released from sensitized lymphocytes in whole blood incubated overnight with purified protein derivative (PPD) from M. tuberculosis and control antigens.

Price for TB Gold/Gamma Interferon (TB Platinum Quantiferon) Test. This TB blood test is highly accurate, with sensitivity of 94% and specificity of 97%. It does not distinguish between active and inactive tuberculosis. 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. The normal, weak and negative mitogen response (respectively) was associated with decreasing hemoglobin, albumin and lymphocyte counts, but increasing neutrophil count and C-reactive protein levels (Table 1). This test is an in vitro diagnostic aid that measures a component of cell-mediated immune reactivity to M. tuberculosis. (2014) 189:77-87. doi: 10.1164/rccm.201302-0365OC, 10. You have taken the Quantiferon Gold TB test, and based on the values, TB can be ruled out. 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. Among tuberculosis patients . Such observations suggest that ongoing infection could be a frequent cause of negative mitogen response. All authors contributed to the article and approved the submitted version. Among tuberculosis patients, a weak mitogen response was associated with a false-negative QFT result (75%) compared to a normal response (20%). 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). 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. Gamma interferon release assays (IGRAs), which measure Mycobacterium tuberculosis-specific CD4 + /CD8 + T cell immunity, are recommended for screening LTI (1). An ongoing infection was independently associated with both a negative (RR = 4.34; 95% CI = 2.94-6.41) and a weak mitogen response (RR = 2.44; 95% CI = 1.66-3.58). The diagnosis is evaluated and decided upon by a medical professional based on the test results, as well as other clinical information. It may vary with age, gender, and other factors.
