This study introduces a new, robust method for transferring analyte concentration values from reference materials to production calibrators using a single instrument and reagents. The procedure minimizes calibration errors and ensures accurate value assignment for diagnostic assays.

Area of Science:

  • Clinical Chemistry
  • Analytical Chemistry
  • Biotechnology

Background:

  • Accurate calibration is crucial for reliable diagnostic test results.
  • Traditional methods for calibrator preparation can be susceptible to errors in calibration curve fitting.
  • There is a need for efficient and robust procedures for transferring concentration values from reference materials to production calibrators.

Purpose of the Study:

  • To develop and present a novel procedure for transferring analyte concentration values from reference materials to production calibrators.
  • To create a method that is robust against calibration curve-fitting errors.
  • To establish a statistically sound approach for determining sample sizes based on precision and accuracy tolerances.

Main Methods:

  • A stochastic approximation algorithm is employed to iteratively determine the analyte concentration.
