Aids in the detection of insulinoma. Do not use to diagnose diabetes mellitus.
Quantitative Chemiluminescent Immunoassay
Within 24 hours
Serum separator tube. Also acceptable: Lavender (EDTA) or pink (K2EDTA).
Allow specimen to clot completely at room temperature. Separate serum or plasma from cells ASAP or within 2 hours of collection. Transfer 1 mL serum or plasma to an ARUP Standard Transport Tube. (Min 0.4 mL)
Heparinized plasma. Vitreous or I.V. fluids. Specimens collected in gray (sodium fluoride/potassium oxalate). Hemolyzed specimens.
After separation from cells: Ambient: 8 hours; Refrigerated: 1 week; Frozen: 1 month
This test reacts on a nearly equimolar basis with the analogs insulin aspart, insulin glargine, and insulin lispro. Insulin detemir exhibits approximately 50 percent cross-reactivity. Test reactivity with insulin glulisine is negligible (< 3 percent). To convert to pmol/L, multiply µIU/mL by 6.0.
No compliance statements are in use for this test.
