What is the half-life of fructosamine?

• A. 3-5 days
• B. 1-2 weeks
• C. 3-5 months
• D. More than 6 months

Answer: (B)

Fructosamine changes with the turnover of circulating serum proteins. Since albumin and other serum proteins have a half-life of roughly 10–14 days, fructosamine levels reflect average glucose over about one to two weeks. That makes this test a short-term indicator of glycemic control, not a few days or several months. Therefore the half-life is about one to two weeks.
