Area of Science:

  • Biomarker research
  • Epidemiology
  • Translational science

Background:

  • Transitional studies are crucial for validating biomarkers.
  • They bridge laboratory experiments and population-based epidemiology.
  • Biomarkers are key indicators of exposure or biological effects.

Purpose of the Study:

  • To characterize and validate biomarkers.
  • To assess biomarker variability and feasibility in field conditions.
  • To optimize biomarker usage and understand confounding factors.

Main Methods:

  • Involves laboratory studies for reliability and accuracy assessments.
  • Includes field studies to evaluate marker feasibility and variability.
  • Utilizes biological specimens from healthy individuals, patients, or workers.

Main Results:

  • Defines the distinct role of transitional studies in biomarker validation.
  • Identifies three functional categories: developmental, characterization, and applied studies.
  • Highlights the blurring line between transitional and etiological studies during validation.

Conclusions:

  • Transitional studies are essential for robust biomarker validation.
  • They provide critical data for applying biomarkers in epidemiological research.
  • Characterizing biomarkers ensures their reliable and accurate use in diverse settings.
