Here are some examples:
Patient A Patient B
Fasting glucose: 90 mg/dL Fasting glucose: 82 mg/dL
Fasting insulin: 4 μIU/mL Fasting insulin: 14 μIU/mL
HOMA-IR: (90 x 4) / 405 = 0.88 HOMA-IR: (82 x 14) / 405 = 2.83
Patient A’s fasting glucose is higher than Patient B’s, but Patient A’s insulin is much lower. By taking both glucose and insulin into account, the HOMA-IR scores show us that even with a lower fasting glucose, Patient B is at greater risk for metabolic complications down the road.
Unless people with diabetes are taking insulin, they waste their time and money when they test their blood sugar.
