Test ID: DME
Diabetes Mellitus Type 1 Evaluation
Method Description 
Describes how the test is performed and provides a method-specific reference
(125)I-labeled recombinant human antigen (glutamic acid decarboxylase 65, islet antigen 2, or insulin) is added to the test serum. If antibody is present, it forms a soluble complex with the (125)I-labeled antigen. Subsequent addition of goat antihuman IgG and IgM precipitates the complex. The amount of radioactivity in the precipitate is proportional to the level of antibody in the serum.(5)
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.
GAD65 Antibody: Monday through Thursday, Sunday; 8 a.m.
Insulin Antibodies: Monday, Thursday; 2 p.m.
IA-2 Antibody: Tuesday, Thursday; 10:00 a.m.
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.
7 days
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
10 days
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
28 days
Performing Laboratory Location The location of the laboratory that performs the test
