Repeatedly reactive sam- ples can be considered positive for antibodies to HAV andtherefore there are indications for past or current infectionwith hepatitis A virus.Borderline (S/CO =0.9-1.1): Samples with absorbance toCut-off ratio between 0.9 and 1.1 are considered borderline. Retesting of ...
Significant negative correlations were observed between log HEV copy number and log hepatitis E virus IgG antibody index in the late acute phase of jaundice for both pregnant women (r = −0.7971, p = 0.0002) and non-pregnant women (r = −0.9117, p = 0.0002). Pregnant women had ...
H epatitis C virus (HCV) is a single-stranded RNA virus belonging to the Flaviviridae family1. HCV infects 3.0% of the world's population and is a major cause of liver disease worldwide2. HCV infection progresses to chronicity in 70%–85% of infected adults3. An estimated 476,000 ...
Hepatitis C virus(HCV) infection is a prominent cause of chronic hepatitis,liver cirrhosis, andhepatocellular carcinoma(HCC), with up to 185 million chronically infected individuals worldwide, most of whom are undiagnosed and untreated.1,2A protective vaccine is not available, and those who clear ...
A positive or "reactive" result on the HBsAb test means that you're immune to the hepatitis B virus. A negative or "non-reactive" result means that you're not immune to the virus. This article explains what the hepatitis B surface antibody test is for, when it is used, and how the...

Virus titers of HEV-positive samples were relatively low (10 3 -10 4 IU HEV RNA/mL). One positive donation was HEV IgG seropositive. CONCLUSION: Routine screening of US source plasma donations for HEV would not substantially improve the safety of most PDMPs. The low prevalence and potential...
IgM antibody to the core antigen can also indicate exacerbation of a chronic infection. IgG antibody to the core antigen (anti-HBc) is less helpful. It can indicate acute, chronic, or resolved infection and does not appear after immunization. Lastly, HbeAg indicates a high level of viral ...
People with positive HBsAg are infectious and can transmit the virus to others. The IgM subclass of antibody to the hepatitis B core antigen (IgM anti-HBc) indicates acute infection while total IgG anti-HBc is a nonspecific marker of infection which can indicate acute, chronic, or resolved ...
