Kraft Prediabetes 4-Hour Profile
The Kraft Prediabetes Profile evaluates insulin resistance patterns by measuring paired glucose and insulin across a four-hour oral glucose challenge.
Serial sampling reveals response curves that can flag early metabolic dysfunction long before fasting values show abnormalities.
- 6 glucose & 6 insulin draws
- 4-hour oral glucose challenge
- Insulin response patterning
- Clinician-ready report

What This Profile Measures
Paired glucose and insulin values are collected at
six time points from fasting through four hours post-challenge to visualize response
curves and insulin pattern types.
- 6 glucose measurements (fasting → 4 hours)
- 6 insulin measurements (fasting → 4 hours)
- Assessment of insulin response patterning
Who Might Benefit
- Patients with normal fasting labs but symptoms suggestive of dysglycemia
- Weight gain, fatigue, post-meal crashes, or family history of diabetes
- Therapy monitoring for nutrition, lifestyle, or medication adjustments
Preparing for the Test
- Overnight fast unless otherwise directed by your clinician
- Avoid strenuous exercise the morning of testing
- Follow lab instructions for the glucose challenge and draw schedule
