Test ID: PINS    
Proinsulin, Plasma

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

Sequential 2-site electrochemiluminescent immunoassay performed on the MesoScale Discovery instrument. The assay uses a monoclonal biotinylated anti-insulin capture antibody and an anti-C-peptide detection antibody labeled with SULFO-TAG. The signal is directly proportional to the amount of proinsulin in the sample. Assay calibration is traceable to the WHO 1st International Standard for human Proinsulin NIBSC code: 09/296. This assay demonstrates no cross-reactivity with insulin or C-peptide.(Unpublished Mayo method)

Day(s) Performed Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.

Tuesday, Thursday

Report Available The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

1 to 6 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

3 months

Performing Laboratory Location Indicates the location of the laboratory that performs the test
