Alternate
Collection Media:
Lavender top tube 3 mL (EDTA) or Pink top tube 6 mL (K2-EDTA)
Minimum:
Preferred Minimum: 1 mL serum or plasma
Absolute minimum: 0.5 mL serum or plasma
Absolute minimum: 0.5 mL serum or plasma
Rejection Criteria:
Heparinized plasma. I.V. fluid. Vitreous fluid. Gray (potassium

Turn Around
Time:
Within 24 hours upon receipt at reference laboratory
Reference Range:
Fasting insulin = 3-19 uIU/mL
Interpretive Data:
To convert to pmol/L, multiply uIU/mL by 6.0. The reference interval
for a fasting insulin is 3-19 uIU/mL.
This assay 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).
