The Fructosamine Test-Plus assay shows improved performance, with less interference from protein and lipids. However, its effectiveness for diabetes mellitus screening remains similar to the original method in populations with low disease prevalence.

Area of Science:

  • Clinical Chemistry
  • Biochemical Assays

Background:

  • Fructosamine assays measure glycemic control over 2-3 weeks.
  • Existing assays can be affected by sample protein and lipid levels.

Purpose of the Study:

  • Evaluate a modified commercial fructosamine assay, Fructosamine Test-Plus.
  • Assess its performance compared to the original method in a large population sample.

Main Methods:

  • The Fructosamine Test-Plus assay was modified with detergent, uricase, and altered reagent concentrations.
  • Primary calibration methods were also changed.
  • Assay performance was evaluated using samples from 2321 health screening participants.

Main Results:

  • Fructosamine Test-Plus demonstrated reduced interference from sample protein concentration.

  • The modified assay showed less susceptibility to hyperlipidemia interference.
  • Assay linearity was extended into the pathological range.
  • Diabetes mellitus screening performance was comparable to the original assay in a low-prevalence population (2.28%).

    • Conclusions:

    • Fructosamine Test-Plus offers enhanced robustness against common interfering substances.
    • Despite improvements, its utility as a diabetes screening tool in low-prevalence settings is similar to previous methods.
