CMUMP-M
MUMPS VIRUS ANTIBODIES, IGG AND IGM (SEPARATE DETERMINATIONS), SPINAL FLUID

Test Code CMUMP-M 
Test MUMPS VIRUS ANTIBODIES, IgG AND IgM (SEPARATE DETERMINATIONS), SPINAL FLUID 
Methodology Immunofluorescence 
Description Useful for aiding in the diagnosis of central nervous infection by mumps virus 
Specimen 0.5 mL (pediatric: 0.2 mL) of spinal fluid. Send specimen refrigerated in a screw-capped, sterile vial. Maintain sterility and forward promptly.

NOTE: WHEN THIS TEST IS ORDERED, BOTH SERUM AND SPINAL FLUID MUST BE SENT. IN ADDITION TO THIS TEST, ORDER "MUMPS VIRUS ANTIBODIES, IgG AND IgM (SEPARATE DETERMINATIONS), SERUM." AN ADDITIONAL CHARGE WILL BE MADE FOR THE COMBINED DETERMINATIONS.
The serum specimen is used to aid interpretation of spinal fluid results. If the spinal fluid result is positive, the serum specimen will determine if spinal fluid results are real or due to blood leaking into the spinal fluid. 

Reference Values IgG: < 1:5
IgM: < 1:10

The presence of IgM class antibodies or a fourfold or greater rise in paired sera IgG titer indicates recent infection. The presence of demonstrable IgG generally indicates past exposure and immunity.
See the Virology section of "Microbiology" for additional information.
