    Three programs for radioimmunoassays (RIA) data processing were developed for programmable calculators. These programs offer advanced statistical analysis, including dose interpolation and quality control, making them accessible for labs without large computer facilities.

    Area of Science:

    • Biochemistry
    • Laboratory Medicine
    • Computational Biology

    Background:

    • Radioimmunoassays (RIA) are crucial for quantifying substances in biological samples.
    • Complex data analysis for RIA often requires access to large computer systems.
    • Limited computational resources in some laboratories hinder advanced RIA data processing.

    Purpose of the Study:

    • To develop and present three distinct software programs for RIA data processing.
    • To implement sophisticated statistical analyses on a small, programmable calculator.
    • To enhance the accessibility of advanced RIA data analysis for laboratories with limited computing facilities.

    Main Methods:

    • Development of three distinct programs for a Texas Instruments Model 59 programmable calculator.

  • Program 1: Weighted logit-log regression for standard curve analysis, dose interpolation, and precision estimation.
  • Program 2: Four-parameter logistic model for dose-response curve fitting and interpolation.
  • Program 3: Analysis of variance (ANOVA) for within-laboratory quality control, including assay precision estimation.

    • Main Results:

    • Successful implementation of weighted logit-log regression and four-parameter logistic models for RIA data.
    • Capability for dose interpolation, precision estimation (percent coefficient of variation), and recovery corrections.
    • Development of a quality control program for calculating within- and between-assay precision using ANOVA.
    • Demonstration that advanced statistical analyses can be performed on inexpensive, portable calculators.

    Conclusions:

    • The developed calculator programs provide comprehensive statistical analysis for radioimmunoassays.
    • These programs democratize advanced RIA data processing, enabling its use in resource-limited settings.
    • The availability of these tools supports robust quality control and accurate quantification in routine laboratory practice.
