Interferon\u2010gamma release assays (IGRAs) are the most widely used test for LTBI screening; however, assessment of IGRA performance in patients with end\u2010stage liver disease is limited. The purpose of this study was to evaluate the prevalence and predictors of indeterminate (INDT) IGRA results in liver transplantation candidates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Between March 2011 and May 2018, we retrospectively analyzed 155 patients undergoing liver transplantation assessment, who underwent IGRA testing (Quantiferon\u2010TB Gold, QFT\u2010G) to exclude LTBI. Characteristics of patients, including age, gender, etiology of liver disease, MELD score, and absolute lymphocyte counts, were compared by QFT\u2010G result (determinate vs INDT).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 155 patients screened, the rate of positive, negative, and INDT results were 5.2%, 69.8%, and 25%, respectively. The only variable independently associated with an indeterminate test on multivariate analysis was MELD score (odds ratio\u00a0=\u00a01.07, 95% CI\u00a0=\u00a01.01\u20101.14 per unit increase; <jats:italic>P<\/jats:italic>\u00a0=\u00a00.014). In 95% of INDT tests, both TB antigen tube and the positive control tube were negative and repeat testing gave the same indeterminate result, suggestive of anergy rather than laboratory error.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our study suggests a high rate of INDT IGRA results during screening of liver transplant candidates for LTBI, associated with severity of liver disease and anergy. Because of the high rate of INDT QFT\u2010G testing in this setting, individualized risk assessment is required including a thorough assessment of clinical risk factors and knowledge of local TB prevalence.<\/jats:p><\/jats:sec>","DOI":"10.1111\/tid.13087","type":"journal-article","created":{"date-parts":[[2019,3,30]],"date-time":"2019-03-30T14:38:16Z","timestamp":1553956696000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["High
