Area of Science:
- Biochemistry
- Immunology
- Clinical Diagnostics
Background:
- Cytokine bioassays and immunoassays are increasingly accessible in clinical settings.
- Laboratories may lack specialized expertise in cytokine biology.
- This accessibility facilitates cytokine level data collection in various diseases.
Purpose of the Study:
- To highlight potential challenges associated with cytokine assays.
- To define essential criteria for validating cytokine measurements in biological fluids.
- To ensure the reliability of cytokine data obtained in clinical research.
Main Methods:
- Review of common interfering factors in plasma and other body fluids.

- This approach supports accurate disease biomarker discovery and monitoring.
Abstract:
Bioassays and immunoassays for cytokines are now widely available for use in clinical laboratories which may have little or no expertise in cytokine biology. Whilst this facilitates the accumulation of data concerning cytokine levels in body fluids in disease, it is based on the assumption that such assays can be used for this purpose. In many cases, the presence of complex interfering factors in plasma and other body fluids require that assays should be subjected to detailed assay validation before confidence can be placed on the results. It is the purpose of this report to outline the potential problems with cytokine assays and the criteria that should be applied before making measurements in biological fluids.
