Quantiferon tb test indeterminate results
An indeterminate QuantiFeron Gold inTube (QFTIT) simply means the result cant be interpreted. It does NOT mean intermediate or borderline positive! Although there are several reasons for an indeterminate QFTIT, a common explanation is an immunocompromised state involving inadequate Tcell response (eg, corticosteroids, HIV, cancer).Received: November 08, 2010; Accepted: March 14, 2011; Published: May 14, 2011. The QuantiFERONTB Gold InTube Test was implemented as an aid for diagnosing tuberculosis infection or disease. The indeterminate results are uncommon but their importance cannot be neglected during diagnosis of tuberculosis infection. quantiferon tb test indeterminate results
Apr 01, 2009 Indeterminate results of the QuantiFERON TB2G test under routine clinical practice are not infrequent. When scoring QuantiFERON TB2G test results for elderly and immunocompromised patients, one must be careful because the possibility of obtaining determinate results may be low even if the test is repeated.

The occurrence of indeterminate results may decrease the clinical usefulness of this test.quantiferon tb test indeterminate results QuantiferonTB Gold, (Client Incubated) The interpretation of the TB Gold Quantiferon Assay is very straight forward as long as it is Positive or Negative; however, an indeterminate result suggests an invalid result. Take into consideration that the assay is measuring the
QFTPlus is a blood test that can help detect TB infection. QFTPlus is a major scientific advance over the 100yearold TB skin test (sometimes called Mantoux, tuberculin skin test, TST or PPD). QFTPlus provides greater accuracy and a more reliable result in a single patient visit. In what situations should quantiferon tb test indeterminate results The Gold InTube (QFTGIT) (QIAGEN Group, Hilden, Germany) test is widely used to screen for latent Mycobacterium tuberculosis infection in patients with inflammatory bowel diseases (IBD) before treatment with a tumor necrosis factor antagonist. The test frequently produces indeterminate results, prompting additional testing. May 29, 2012 Results. The median TB AgNil and the median MitogenNil were shown to be 0. 015 (IQR, ) and 0. 095 (IQR, ) in the indeterminate group, of whom 58. 3 (7 cases) showed negative TST results, and 33. 3 (3 patients with TB and 1 patient with nonTB group) showed positive TST results. How can the answer be improved? Approved by the US Food and Drug Administration (FDA), and CE marked, QFT, like the tuberculin skin test (TST), can be used as an aid in the diagnosis of latent tuberculosis infection and TB disease.
