Assay validation characterizes biological assay performance, enabling accurate results. Careful control of reagents and procedures ensures reliable quantitation and interpretation, overcoming inherent biological variation.

Area of Science:

  • Biochemistry
  • Analytical Chemistry
  • Pharmacology

Background:

  • Biological assays possess inherent variability, often used to explain unexpected results.
  • Historically, this variation has hindered precise interpretation of assay outcomes.
  • Standardization is crucial for reliable biological assay data.

Purpose of the Study:

  • To define assay validation as a critical process for evaluating assay performance.
  • To emphasize the importance of controlling variables in biological assays.
  • To demonstrate that validated biological assays permit accurate quantitation and interpretation.

Main Methods:

  • Characterization of assay performance metrics.
  • Implementation of strict procedural controls.
