Serological Test:A serological test is one type of laboratory procedure. It is carried out using blood serum. It is mainly used to detect antibodies. Examples include the flocculation test and neutralization test.Answer and Explanation: A fluorescent antibody test is used to study the intracellula...
Infection with hepatitis B virus (HBV) may lead to acute or chronic hepatitis. HBV infections were previously much more frequent but there are still 240 million chronic HBV carriers today and ca. 620,000 die per year from the late sequelae liver cirrhosis or hepatocellular carcinoma. Hepatitis B...

For viruses that exist in multiple strains or have the ability to mutate under immunologic pressure, either the antibodies must be targeted against a conserved epitope shared between strains and unlikely to mutate, or the vaccine must include antigens from each relevant strain. In addition, ...
Currently, VLP vaccines against the hepatitis B virus and human papillomavirus have been approved by the United States Food and Drug Administration (FDA) for clinical purposes [7]. Nevertheless, VLP vaccines against respiratory viruses continue to remain under development. Furthermore, despite the ...

It is usually due to an immunoglobulin G (IgG) autoantibody that may activate complement (C) if present at high titer or if IgG1 and IgG3 subclasses are prevalent. The cornerstone of diagnosis is the direct antiglobulin test (DAT), which may be positive with anti-IgG antisera (70% of ...
How do we test for DAT-negative AIHA? The identified mechanisms by which erythrocyte antibody escapes recognition by standard DAT are listed in Table 3.81,82 There are several “enhanced” DATs that can be performed to detect one or more of the described mechanisms. The more common enhanced ...
Understanding what determines the between-host variability in infection dynamics is a key issue to better control the infection spread. In particular, pathogen clearance is desirable over rebounds for the health of the infected individual and its contact
Serological tests for hepatitis and HIV were negative and the venereal disease research laboratory (VDRL) test was positive with a titer of 1:1024. Membranous glomerulonephritis secondary to syphilis * Further tests to assist with the diagnosis include antinuclear antibody profile, antineutrophil cytoplasm...
