HOMEOSTATSIS MODEL ASSESSMENT OF INSULIN RESISTANCE (HOMA-IR)

Test Code HMAIR 
Test HOMEOSTATSIS MODEL ASSESSMENT OF INSULIN RESISTANCE (HOMA-IR) 
Methodology Glucose - Spectrophotometric (SP)
Insulin- Electrochemiluminescence Immunoassay (ECL) 
Description For identifying insulin resistance as a risk factor for future stroke or myocardial infarction in non-diabetic patients with a clinical history of ischemic stroke or transient ischemic attack (TIA)

This test is intended for fasting adult patients only

This panel includes:
Glucose (FBS)
Insulin (INSLN)
Insulin Resistance Index

Specimen Draw blood in either a plain, red-top tube or serum gel tube from a fasting patient. Spin down and send 1.0 mL of serum frozen in plastic vial. Frozen specimen preferred, but refrigerated is acceptable. Insulin is stable for 24 hours at 2 - 8 C.

No sample should be collected on patients until at least 14 days after a stroke or TIA

No sample should be collected on patients receiving therapy with high biotin doses (i.e. > 5 mg/day) until at least 8 hours after the last biotin administration. 

Reference Values Glucose (FBS) 70 - 99 mg/dL
Insulin (INSLN) 2.6 - 24.9 U/mL
Insulin Resistance Index 0.0 3.0 
Analytic Time 1 Day 
Day(s) Test Set Up Monday through Sunday 
CPT Code(s) 82747  Glucose (FBS)
83525  Insulin (INSLN)
