A new standardized test for hepatitis B virus (HBV) DNA with increased sensitivity and range over previous assays (30 to 106 HBV genomes/test) was evaluated in this study. The quantitative results from the test have been validated using international reference specimens of known titer and a ...
The purpose of this descriptive, quantitative study was to examine B immunity in high risk health care workers 7 years post immunization. The study related immunity to age and site of injection, and also described titer results. The study sample was composed of 42 health care workers from areas...
(5) a false-positive result. The role of quantitative HBsAg assays is being evaluated formonitoring patientswith chronic HBV infection. The presence of HBV e antigen (HBeAg) and the absence of anti-HBe are markers of greater infectivity and correlate with increased risk of progression to chronic...
Boa Z, Dai H, Dashtseren B, Yagaanbuyant D, Genden Z, Dashdorj N, Bungert A, Dashdorj N, Glenn JS. A novel quantitative microarray antibody capture assay identifies an extremely high hepatitis delta virus prevalence among hepatitis B virus–infected Mongolians. Hepatology. 2017;66(6):1739...
We performed a quantitative study of serum hepatitis B virus (HBV) markers, including new parameters such as pre-S1 antigen (Ag), pre-S2 Ag, and anti-HBx, in 88 chronic hepatitis B surface antigen (HBsAg) carriers. New IMx assays for HBsAg and immunoglobulin M (IgM) anti-HBc detection ...
31,45 If there is evidence of past or present HBV infection, quantitative HBV DNA viral load should be tested, and patients should be referred to a hepatologist for evaluation. Both active and inactive carriers need to start prophylactic antiviral treatment. Following the most recent guidelines ...
EID is as sensitive as IEOP, requires less antiserum, and is quantitative. Results may be obtained within 45 minutes if high-titer antiserum is available. Using this technique, 26 HAA-positive sera were identified among 10,303 potential blood donors during a 3 month period.DOI: 10.1016/S0091...
End of treatment HBsAg: Hepatitis B surface antigen cp: Copies LLD: Lower limit of detection LQD: Limit of quantitative detection ALT: Alanine aminotrasferase VR: Virological relapse CR: Clinical relapse IU: International units ULN: Upper limit of normal ...
22 In addition to quantitative viral factors, HBV genotypes C and D, basal core promoter mutant, and pre-S deletion mutant are qualitative viral factors associated with an increased risk of cirrhosis and HCC.23 Integration of risk of hepatitis B viral factors for HCC are recommended to be ...
Viral hepatitis represents a disease entity caused by at least five unrelated viruses whose primary tissue tropism is the hepatocyte. Hepatitis A is an acute self-limited disease resulting from infection with hepatitis A virus (HAV). Infection with hepat
