Test ID: MMRV    
MMRV Immune Status Profile, Serum

Method Description Describes how the test is performed and provides a method-specific reference

The BioPlex 2200 MMRV IgG kit uses multiplex flow immunoassay technology which allows for the detection and identification of many different antibodies in a single tube. Four different populations of dyed beads are coated with antigens to identify the presence of IgG-class antibodies associated with measles, mumps, rubella, and varicella-zoster. The patient sample, sample diluent, and bead set reagent are mixed together in a reaction vessel and the mixture is incubated at 37 degrees C. After a wash cycle, anti-human IgG antibody conjugated to phycoerythrin (PE) is added to the dyed beads and this mixture is incubated at 37 degrees C. Excess conjugate is removed during a wash cycle and the beads are re-suspended in wash buffer. The bead mixture next passes through the detector and the identity of the beads is determined by the fluorescence of the dyes. The amount of antibody captured by the antigen on the bead is determined by the fluorescence of the attached PE. Raw data is calculated in relative fluorescence intensity (RFI).

 

Three additional dyed beads, an internal standard bead, a serum verification bead, and a reagent blank bead are present in each reaction mixture to verify detector response, the addition of serum to the reaction vessel and the absence of significant non-specific binding in serum.(Package insert: BioPlex 2200 System MMRV IgG, Bio-Rad Laboratories Clinical Diagnostics Group, Hercules, CA)

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.
