Order Fructosamine Blood Test from JustLabs for $14 ($32 all-in for a single-test order: $14 + one $18 lab & physician order fee per order). Price includes lab processing at Quest Diagnostics. No insurance required.
Fructosamine measures your average blood sugar over the past 2-3 weeks - a shorter window than HbA1c. It's especially useful when HbA1c may be inaccurate or when you need to see faster changes in glucose control.
Fructosamine is formed when glucose attaches to proteins in your blood, primarily albumin. Because albumin has a shorter lifespan than red blood cells (used for HbA1c), fructosamine reflects average blood sugar over a shorter 2-3 week period rather than 2-3 months.
This test is particularly valuable in situations where HbA1c may not accurately reflect blood sugar control:
- Recent changes in diabetes treatment (to see improvement faster)
- Conditions affecting red blood cell lifespan (sickle cell, hemolytic anemia, recent blood loss)
- Hemoglobin variants that interfere with HbA1c testing
- Pregnancy (when blood sugar control can change rapidly)
While not a replacement for HbA1c in routine diabetes monitoring, fructosamine fills an important niche for short-term glucose assessment.

What's Measured
What This Test Measures
This test measures glycated serum proteins (primarily albumin) in your blood, reported in µmol/L. Normal fructosamine is typically 200-285 µmol/L. Levels above this indicate elevated average blood sugar over the past 2-3 weeks.
Who Should Consider This Test
People with conditions affecting HbA1c accuracy, those needing short-term blood sugar assessment, pregnant women with diabetes, patients who recently changed diabetes treatment and want to see results faster, and anyone with hemoglobin variants.

Understanding Your Results
Normal fructosamine is typically 200-285 µmol/L. Higher values indicate elevated average blood sugar. Because reference ranges can vary by lab and protein levels, results should be interpreted with clinical context. Abnormally low albumin can affect fructosamine accuracy.
