Abstract:
Objective:To evaluate the diagnostic performance of Loop-mediated isothermal amplification (LAMP) in the diagnosis of Hepatitis B Virus (HBV) infection using Meta-analysis.
Methods:Literatures about LAMP in the diagnosis of HBV throughPubMed database of the National Library of Medicine, the EMBASE database of the Dutch Medical Digest, the Cochrane Clinical Trials Database, China Science Periodical Database, CSPD and the China National Knowledge Infrastructure (CNKI) were searched from 2000 to 2016, and the Language limited to Chinese and English. English search terms include: LAMP, Loop-mediated isothermal amplification, HBV, hepatitis B virus; Chinese search terms include: loop-mediated isothermal amplification technology, HBV, hepatitis B virus. The keywords and free words are combined to search the literature, and the references mentioned in the retrieval literature are searched twice. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio (DOR), Q index as well as area under summary receiver operating characteristic curve (SROC) were calculated with Stata 12.0 software.
Results:A total of 12 literatures with 1 494 cases were included. The pooled sensitivity, specificity, positive likelihood ratio and negative likelihood ratio were 0.922 (95%CI: 0.905-0.937), 0.860 (95%CI: 0.818-0.896), 0.093 (95%CI: 0.048-0.182), and 15.400 (95%CI: 2.003-118.380), respectively. The DOR, area under SROC and Q index were 311.090 (95%CI: 95.841-1 009.800), 0.986 (95%CI: 0.974-0.998) and 0.949 (95%CI: 0.922-0.976), respectively. Deek's test indicates that no publication bias were found (P=0.140).
Conclusion:LAMP is worth to be popularized in field tests and primary-level hospitals tests.
