What is the reference range for fructosamine in umol/L?

• A. 100-150 umol/L
• B. 205-285 umol/L
• C. 300-350 umol/L
• D. 350-450 umol/L

Answer: (B)

Fructosamine reflects the average blood glucose over the previous 2–3 weeks by measuring glycated serum proteins, mainly albumin. The commonly accepted reference range for adults is about 205–285 μmol/L. This range fits because it corresponds to normal protein turnover and typical albumin levels; values above suggest higher mean glucose in the short term, while values below indicate lower short-term glycemia or altered protein status. Other option ranges are outside what’s typically observed in a normal, healthy adult.
