Exploring the eligibility of all reported lipoarabinomannan-testing assays in different clinical situations: a systematic review and meta-analysis of 97 articles.

• Selecting proper lipoarabinomannan-testing assays is the key to enhance the detection rate. • Electrochemiluminescence was recommended for tuberculosis/HIV patients, especially taking urine as a sample. • Enzyme-linked immune sorbent assay was recommended as a reliable detection for smear-positive Africans. How to choose proper lipoarabinomannan-testing assays for diagnosing tuberculosis (TB) in different populations baffles clinicians. This work assessed all reported lipoarabinomannan assays' performance and aimed to identify the eligibility of each assay and offer guidance for clinicians. We searched PubMed, Embase, and Web of Science until August 23, 2020. The risk of bias was evaluated by QADAS-2. Heterogeneity was evaluated by the Cochran Q test and I2. Sensitivity and specificity were pooled by a bivariate mixed model (register number: CRD42021270506). A total of 97 articles, covering 144 trials, 16 assays, 45,679 participants, and eight sample types, were divided into five groups. Electrochemiluminescence (ECL) had a sensitivity of 65%, specificity of 92%, and an area under curve (AUC) of 0.85 in diagnosing pulmonary TB in adults. ECL showed a promising diagnostic ability (sensitivity: 78%; specificity: 88%; AUC: 0.88) in patients with HIV, especially for urine detection (sensitivity: 90%; specificity: 89%; AUC: 0.95). The enzyme-linked immune assay showed a preference for diagnosing TB in Asians and Africans, especially in Africans who were smear-positive (sensitivity: 80%; specificity: 88%; AUC: 0.91). ECL was recommended for diagnosing pulmonary TB in adults, especially for TB/HIV co-infection. Taking urine as a sample further enhanced ECL's diagnostic performance. Enzyme-linked immune assay was recommended as an additional TB-related detection for smear-positive Africans. [ABSTRACT FROM AUTHOR]
