VZV (Chickenpox) Antibodies IgG
Since the introduction of varicella vaccination in several countries, there has been an urgent need for commercially available test procedures that allow highly sensitive and specific quantitative determination of the varicella-zoster virus (VZV)-specific immune status, including immunity postimmunization. To investigate immunologic correlates of protection and VZV reactivation, we characterized specific immunity in 207 nonsymptomatic immunocompetent and 132 immunocompromised individuals in comparison with patients with acute herpes zoster. Chickenpox most commonly affects children between 5 and 8, although adults and younger children may get it. Shingles causes a rash on one side and may develop into long term nerve pain. Immunoenzymatic method for the qualitative determination of IgG and IgM-class antibodies to Varicella in human serum, using a disposable device applied on the Chorus and Chorus TRIO instruments.The test is based on the ELISA principle (Enzyme Linked ImmunoSorbent Assay) which uses the reaction between the antibodies present in the tested sample and the immobilized antigen bound to solid phases.The immunoglobulins bind to the antigen through incubation with diluted human serum.The disposable devices contain all the reagents to perform the test when applied on the Chorus instruments. They should report any symptoms to the occupational health department without delay. In addition, 31 spinal fluid samples were tested by all three methods.

It furthermore shows the importance of weighting the different antibody indices included in MRZR and suggest that patients with positive MRZR are candidates for an early begin of immunomodulatory therapy. No statistically significant differences were observed between age, gender, place of residence, risk of exposure, marital status, educational level, working experience and seropositivity.
