Task: Answer Verification
Input (English): Question: Does serum α-hydroxybutyrate ( α-HB ) predict elevated 1 h glucose levels and early-phase β-cell dysfunction during OGTT?
Answer: Fasting serum α-HB levels predicted elevated 1 h glucose during OGTT, potentially due to impaired insulin secretion kinetics. This association persisted even in patients with an otherwise normal insulin-glucose homeostasis. Measuring serum α-HB could thus provide a rapid, inexpensive screening tool for detecting early subclinical hyperglycemia, β-cell dysfunction, and increased risk for diabetes.
Output (English): yes
