Insulin, Random : 0070107

Mnemonic: INSULIN R

Methodology: Quantitative Chemiluminescent Immunoassay
Performed: Sun-Sat
Reported: Within 24 hours
Specimen Required: Collect: Serum separator tube. Also acceptable: Lavender (EDTA) or pink (K2EDTA).

Specimen Preparation: 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: 0.5 mL)

Storage/Transport Temperature: Frozen.

Unacceptable Conditions: Heparinized plasma. I.V. fluid. Gray (potassium oxalate/sodium fluoride). Hemolyzed specimens.

Stability (collection to initiation of testing): After separation from cells: Ambient: 8 hours; Refrigerated: 1 week; Frozen: 1 month
Reference Interval:
Not established.
Interpretive Data: To convert to pmol/L, multiply µIU/mL by 6.0. The reference interval for a fasting insulin is 3-19 µlU/mL.

This assay reacts on a nearly equimolar basis with insulin aspart, insulin glargine, and insulin lispro.
CPT Code(s): 83525
