[Standardized protocol for radioimmunoassay evaluation and quality control (author's transl)]

Area of Science:

• Biochemistry
• Analytical Chemistry
• Immunology

Context:

• Radioimmunoassay (RIA) is a widely used technique for quantifying substances like hormones.
• Accurate standard curve construction is crucial for reliable RIA results.
• Existing methods for RIA standard curve generation can be complex and computationally intensive.

Purpose:

• To evaluate and recommend the most favorable method for constructing radioimmunoassay (RIA) standard curves.
• To develop a standardized concept for RIA evaluation and quality control.
• To facilitate the computation and improve the reliability of RIA analyses.

Summary:

• The logit-log transformation is presented as the most favorable method for RIA standard curve construction, yielding a linear dose-response relationship.
• Truncating the standard curve to the effective dose range (ED85 to ED15) allows for linear regression analysis with unweighted data, simplifying computation.
• A standardized protocol for RIA analysis, including specific parameters and control samples, is proposed for consistent evaluation and quality control.
• The proposed system, executable on a low-cost desk-top calculator, aids in assay optimization and establishes a basis for international standardization.

Impact:

• Simplifies RIA data analysis through a standardized, computationally efficient approach.
• Enhances the accuracy and reliability of hormone quantification using RIA.
• Provides a framework for robust quality control, essential for assay optimization and inter-laboratory standardization.
