We collected data from hepatitis B and C suspected clients' serology Laboratory registration logbooks using a structured checklist. Patient information, including age, sex, laboratory results, and year of diagnosis, was obtained from the serology laboratory registration logbooks. Quality control We used...
Serology: Antibodies to the various antigens appear in the blood. Six weeks after infection thesurface antigen(HBsAg) appears in the blood, followed two weeks later by the e antigen (HBeAg), at the time of maximal viral replication.

In the B virus fatality resulting from ocular exposure, the patient did not develop a dendritic corneal lesion typical of ocular herpes infections; rather, she developed a swollen, painful orbit with conjunctivitis (CDC, 1998). As the clinical signs in this patient progressed, she developed ret...

Serology: HAV IgM antibody diagnostic, may be positive 5-10d prior to the onset of sx. IgM anti-HAV remains elevated for up to 12 months after the resolution of infection. Note: testing of asymptomatic people discouraged due to false-positive rates of the IgM assay and consequent demands...
The HCV genome also encodes several non-structural proteins known as NS1-5(a/b). NS3-5 are commonly used together as antigens in immunoassays for the detection of anti-HCV in patient blood samples [5]. For these assays, the antigens are used to capture the patient’s antibodies that ...
hepatitis B exposure, a post-vaccination serology 1–6 months after the last dose should be done. Patients without detectable anti-HBs titers after primary series should begin a standard three-dose series and have serology 1 month after each dose for up to three doses until they seroconvert,...
We defined all-negative HBV serology as being negative for HBsAg, anti-HBs and anti-HBc; vaccination-type serology as being positive only for anti-HBs due to HBV vaccination; past infection as being negative for HBsAg but positive for both anti-HBs and anti-HBc; HBV infection as being posit...
