Turn Around Time:

5 days 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 insulin aspart, insulin glargine, and insulin lispro.

Comments:

Allow serum to clot completely at room temperature. Separate serum or plasma from cells ASAP.

Test Limitations:

This assay reacts on a nearly equimolar basis with insulin aspart, insulin glargine, and insulin lispro.
