Fasting Insulin Resistance Index (FIRI) Blood Test
This test measures the hormone or endocrine marker named in the product title. Hormone testing may help assess endocrine function or investigate symptoms when selected for an appropriate clinical reason.
Hormone concentrations can vary with time of day, medication, menstrual cycle, age, and other factors. Results should be interpreted using the laboratory’s reference intervals and relevant clinical context.
Some hormone tests require timed collection or special preparation. Confirm specimen type, timing, preparation, and turnaround instructions with the laboratory before testing.
