Collecting urine with cotton balls is a safe and effective method for measuring antioxidants and oxidative stress markers in clinical and research settings. This pilot study confirms its utility for both applications.

Area of Science:

  • Biochemistry
  • Clinical Chemistry
  • Urology

Background:

  • Accurate urine sample collection is crucial for reliable biomarker analysis.
  • Traditional urine collection methods can be cumbersome.
  • Novel, less invasive collection techniques are needed for clinical and research applications.

Purpose of the Study:

  • To evaluate the efficacy and safety of using cotton balls for urine collection.
  • To compare cotton ball urine collection with direct urine collection methods.
  • To assess the suitability of cotton ball samples for antioxidant and oxidative stress marker analysis.

Main Methods:

  • A pilot study involving 21 adult participants.
  • Direct urine collection was compared with urine collection using cotton balls.
