We evaluated GenoType Mycobacteria Direct (GTMD), a novel commercial assay based on nucleic acid sequence-based amplification technology, for the detection of Mycobacterium tuberculosis complex, M. avium, M. intracellulare, M. kansasii, and M. malmoense directly from clinical specimens. A total of 134 respiratory and extrapulmonary samples from 65 patients were processed. Sensitivity, specificity, positive predictive, and negative predictive values for GTMD were 92, 100, 100, and 77%, respectively. The GMTD technique is useful, reliable, and rapid when used during the normal routine of a clinical laboratory.
我们评估了基于核酸序列扩增技术的新型商业检测方法——基因分型分枝杆菌直接检测法(GTMD),用于直接从临床标本中检测结核分枝杆菌复合群、鸟分枝杆菌、胞内分枝杆菌、堪萨斯分枝杆菌和马尔默分枝杆菌。对65例患者的134份呼吸道和肺外样本进行了检测。GTMD的敏感性、特异性、阳性预测值和阴性预测值分别为92%、100%、100%和77%。在临床实验室的常规检测中使用时,GMTD技术是有用、可靠且快速的。
