2.Objective To study the optimal dilution of hepatitis B surface antigen(HBsAg) quantitative in common serological patterns by electrochemiluminescence immunoassay(ECLIA),and to explore the correlation of which with HBV-DNA contents.目的:探讨电化学发光免疫分析法(ECLIA)常见血清学模式HBsAg定量分析最适稀释...
The mean difference of the quantitative HBsAg level between the two assays was 1762.5 IU/mL in the Bland鈥揂ltman plot. Conclusions: The HISCL HBsAg assay, with a highly sensitive LoQ of 0.03 IU/mL, showed similar analytical performance in HBsAg quantification to the Elecs...
Group B comprised 52 patients with chronic HBV infection, all of whom haddetectable HBsAg, anti-HBc antibodies, and HBV DNA. Initial genotype determi-nation was done with the INNO-LiPA HBV genotyping assay (Innogenetics, Gent,Belgium), a reverse hybridization assay that targets a portion of the...
Chronic hepatitis B is a major global health problem, affecting more than 240 million people worldwide and leading to one million deaths each year [1]. Although, the prevalence of chronic HBV infection varies geographically: in sub-Saharan Africa, the seroprevalence of HBs antigen (HBsAg) in th...

(HBsAg) carriers (European, 2012). Morbidity and mortal- ity are linked to the persistence of viral replication with hepatic complications developing in 15–40% of chronically infected indi- viduals (Thibault et al., 2007). HBV-related end-stage liver disease and HCC are responsible for more...
Quantitative hepatitis B surface antigen titres in Chinese chronic hepatitis B patients over 4 years of entecavir treatment (Roche Diagnostics, Penzberg, Germany).Results: The mean baseline HBV DNA and qHBsAg were 7.51 log(10) copies/ml and 3.78 log(10) IU/ml, ... EQ Chen,TT Wang,L Bai...
本研究中,只检测出人类免疫缺陷病毒抗体阳性检1例,阳性率远低于国内其他报道J,可能与兵员的来源不同有关。应该指出的是,AIDS发病率在逐年增长,提高兵员质量,防止不良人员混人部队,应是一个多方面的工作,地方武装郎在接受兵员时应严把质量关,杜绝后门兵、关系兵。检验科医师在检测抗HIV过程中检测者应严格按照操作...
