Sleep Balance Hormones

In the intricate symphony of our body's functions, hormones play a pivotal role. Understanding the nuances of hormonal fluctuations throughout the day is crucial for comprehensive health assessment. Urinary Diurnal Hormones (UDH), a groundbreaking technique developed by ZRT, employing urine strips to capture the circadian rhythm of hormones. In this blog, we'll explore the significance of UDH, its profiles, and how it can shed light on various health concerns.

Understanding Urinary Diurnal Hormones:

ZRT has pioneered a technique utilizing urine strips for the circadian rhythm collection of hormones. By tailoring the collection periods to align with key points in a patient's day, UDH provides a unique perspective on hormone levels. The morning collection captures night cortisol; the second-morning collection reflects the awakening period, the evening collection represents the afternoon, and the nighttime collection unveils the evening hormone levels. These insights allow for a comprehensive understanding of hormonal rhythms.

Profiles Offered by UDH:

  1. UDH I Profile:
  • Dried Urine: Free Cortisol x 4, Free Cortisone x 4, Crtn
  • Tailored for a focused assessment of cortisol and cortisone levels.
  1. UDH II Profile:
  • Dried Urine: Free Cortisol x 4, Free Cortisone x 4, Melatonin (MT6s) x 4, Crtn
  • Expand the assessment to include melatonin, offering insights into sleep-wake cycles.
  1. UDH III Profile:
  • Dried Urine: Free Cortisol x 4, Free Cortisone x 4, Melatonin (MT6s) x 4, NE x 4, Epi x 4, Crtn
  • A comprehensive profile encompassing adrenal hormones (epinephrine and norepinephrine) alongside cortisol and melatonin.

Considerations for UDH Testing:

UDH testing is a valuable tool for addressing a range of health concerns:

  • Fatigue: Uncovering hormonal imbalances contributing to persistent fatigue.
  • Sleep Disorders: Assessing melatonin levels for insights into sleep quality.
  • Inflammatory Issues: Monitoring cortisol levels, a marker of inflammation.
  • Depression: Examining hormonal patterns associated with mood regulation.
  • Blood Sugar Dysfunction: Understanding cortisol's role in glucose metabolism.
  • Panic Attacks: Identifying adrenal hormone fluctuations linked to anxiety.
  • Weight Gain: Exploring hormonal imbalances influencing metabolic processes.

Creatinine Correction for Precision Results:

In all UDH samples, creatinine is measured to correct results for urine dilution. This meticulous approach ensures the accuracy of the hormonal assessments, providing a reliable foundation for informed decision-making.


Urinary Diurnal Hormones open a window into the intricate dance of hormones throughout the day, offering valuable insights for personalized health management. The UDH profiles by ZRT provide a nuanced understanding of cortisol, cortisone, melatonin, epinephrine, and norepinephrine levels, empowering individuals and healthcare professionals to address a spectrum of health concerns. By embracing this innovative approach, one can unlock the secrets of hormonal rhythms and embark on a journey towards optimal well-being.
