Area of Science:

  • Sports Science
  • Biochemistry
  • Analytical Chemistry

Background:

  • Continuous Erythropoietin Receptor Activator (C.E.R.A.) is a third-generation erythropoiesis-stimulating agent (ESA).
  • C.E.R.A. abuse has been identified as a doping method in endurance sports.
  • Developing reliable detection methods is crucial for anti-doping agencies.

Purpose of the Study:

  • To evaluate an enzyme-linked immunosorbent assay (ELISA) for detecting C.E.R.A. in serum samples.
  • To assess the assay's performance for anti-doping applications.
  • To propose a detection strategy combining ELISA with isoelectric focusing.

Main Methods:

  • An enzyme-linked immunosorbent assay (ELISA) was developed and tested.
  • A pilot excretion study with six subjects receiving C.E.R.A. was conducted.
  • Assay performance was validated for reproducibility and applicability.

Main Results:

  • The ELISA demonstrated excellent reproducibility for C.E.R.A. detection.
  • Validation confirmed the assay's suitability for anti-doping purposes.
  • The proposed screening and confirmation strategy showed high potential for detecting C.E.R.A. abuse.

Conclusions:

  • The developed ELISA is a viable high-throughput screening method for C.E.R.A.
  • Combining ELISA with isoelectric focusing enhances C.E.R.A. detection capabilities.
  • This strategy can effectively combat C.E.R.A. doping in sports.
