This test has been largely replaced by haemoglobin A1c for monitoring diabetics .
Specimen sent to Northland Pathology Laboratory (NPL) (Northland Path Lab) for processing.
Units: umol/L
Reference ranges:
|
200 - 300 |
physiological level |
|
300 - 400 |
indicates elevated mean blood glucose level |
|
> 400 |
indicates poor diabetic control |
|
150 - 260 |
normal level in pregnancy |
Uncertainty of Measurement: 10%
High albumin turnover states (such as proteinuria in diabetic nephropathy) falsely lower fructosamine concentrations.
Fructosamine is falsely low in obese patients.
Fructosamine is glycated albumin and is an index of the average glucose concentration over the preceding 1 - 3 weeks (compared with 2 - 3 months for HbA1c).
Fructosamine can be useful when HbA1c is invalid, due to increased haemoglobin turnover (haemolysis or chronic blood loss), or when rapid changes in glycaemic control need to be measured.
