Toxoplasma gondii Antibody, IgM, Serum
Method Description Describes how the test is performed and provides a method-specific reference
The VIDAS TOXO IgM system (bioMerieux Inc, Durham, NC) is an automated serologic test for use on the VIDAS analyzer, which employs the enzyme-linked fluorescence assay (ELFA) technique. The assay uses a 2-step EIA sandwich method. A pipette tip-like device, the Solid Phase Receptacle (SPR), is coated with goat anti-IgM antibodies and serves as the solid phase as well as the pipettor for the assay. The sample is diluted and cycled in and out of the SPR. Subsequently Toxoplasma gondii antigen, followed by mouse anti-Toxoplasma gondii antigen-conjugated antibodies are cycled through the SPR. A fluorescent substrate, 4-methylumbelliferyl phosphate, is added to the SPR, which catalyzes the conversion of the conjugated substrate to a fluorescent product. The intensity of the fluorescence is measured by the optical scanner of the instrument.(Package insert: VIDAS TOXO IgM, BioMerieux, Durham, NC)

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
Monday through Saturday, Varies
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.
Same day/1 day
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
Performing Laboratory Location The location of the laboratory that performs the test
