Hepatitis B Surface Antibody, Quantitative Test code(s) 8475 Question 1. What is the clinical indication for hepatitis B surface antibody quantitation? Question 2. What is the hepatitis B surface antibody? Question 3. How is the quantitative hepatitis B surface antibody (anti-HBs) test performed...
hepatitis B virus; HCV, hepatitis C virus; HBsAg, hepatitis B surface antigen; anti-HBc, hepatitis B core antibody; anti-HBs, hepatitis B surface antibody; HBV DNA quant, quantitative HBV DNA; ALT, alanine aminotransferase; TDF, tenofovir disoproxil fumarate; ETV, entecavir; DAA, direct-acting...
How do you interpret HCV antibody "reactive” and HCV RNA “not-detected” results? Question 6. Is it possible to have HCV infection and have a non-reactive HCV antibody test result? Question 7. What proportion of HCV antibody-reactive specimens are found to contain HCV RNA upon reflex ...
In 1989, the infectious transmissible agent was identified and named hepatitis C virus (HCV) and, soon enough, the first diagnostic HCV antibody test was developed, which led to a dramatic decrease in new infections. Today, HCV infection remains a global health burden and a major cause of ...
and formation of hepatitis B surface antibody (anti-HBs), allowing patients to achieve durable immunity with REP 9 AC and its modified form [94,95]. In a study of 12 HBeAg-positive CHB patients, the NAP HBsAg release inhibitor REP2139-Ca was given for 20–38 weeks, with response defined...
be contacted.Six HLA-A2-negative AHB patients,18 HLA-A2-positive chronic HB patients and 6 HLA-A2-positive normal persons served as controls.The CTL was stained by fluorescence-labeled anti-CD3 monoclonal antibody,anti-CD8 monoclonal antibody and HBV epitopic pentamers(S183-191,S335-343),and ...
Investigation of Primary Human Immunodeficiency Virus Infection in Patients Who Test Positive for Heterophile Antibody In light of a recent report of 3 false-positive results of Epstein-Barr virus heterophile tests caused by HIV infection, we sought to assess the frequency ...

Taken together, UT1.1, UT1.2, and UT1.3 appeared to be a bystander autoantibody, an anti-HCV antibody, and a cross-reactive autoantibody, respectively. CDR-H3 amino acid hydrophobicity was associated with cryoprecipitation. Chronic HCV infec- tion is a good model of infection-driven ...
In such a model, one might expect that even low levels of core expression might lead to an increased susceptibility of infected cells to FasL or anti-Fas antibody, as has been demonstrated Hahn et al 2000, Taya et al 2000. With enhanced levels of core expression that can be achieved ...
