Fructosamine
Fructosamine measures average blood sugar levels over the past 2 to 3 weeks by detecting glycated proteins in the blood. It is useful when HbA1c results may be unreliable.
Category: Diabetes & Glycemic
Also known as: fructosamine, glycated albumin, glycated serum protein, fruktozamin
Reference range: 200–285 µmol/L (Source: ABIM)
Standard unit: µmol/L
High values may indicate
High fructosamine levels may indicate poorly controlled diabetes or hyperglycemia over recent weeks.
Low values may indicate
Low fructosamine levels are generally not clinically significant but may be seen with low albumin levels (hypoalbuminemia) or improved blood sugar control.
Frequently asked questions
- What is a normal Fructosamine level?
- A typical reference range for Fructosamine is 200–285 µmol/L (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is Fructosamine measured in?
- Fructosamine is most commonly reported in µmol/L. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do Fructosamine reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track Fructosamine over time?
- Yes. Upload results from any lab and BloodId charts your Fructosamine over time against its reference range, so you can see whether the trend is rising, falling, or stable.
