The Rhein Advantage

Get the Whole Picture

Rhein Labs is an independent research laboratory with a unique focus on hormone profiling. You can benefit from our specialization in the comprehensive measurement, examination and interpretation of adrenal and sex hormone levels using the 24-hour urinary steroid hormone profile (USHP). This test, when accompanied by interpretation drawing from Rhein Labs’ in-depth perspective, delivers a wealth of information and benefits to healthcare providers, research institutions, universities and pharmaceutical developers — and, ultimately, to the people they serve.

Complex, ever-changing hormonal interactivity demands that sampling techniques yield results which are accurate, relevant and reproducible.

Comprehensive Analysis: Industry-Leading Interpretation

Healthcare practitioners and researchers alike can take full advantage of the most advanced, comprehensive steroid hormone level testing available today. Experts understand the importance of the delicate balance inherent in steroid hormone production and metabolism. Complex, ever-changing hormonal interactivity demands that sampling techniques yield results which are accurate, relevant and reproducible.

Professionals appreciate the superiority of the 24-hour USHP over the narrow, scientifically dubious results derived from saliva and blood-spot sampling techniques. These tests are promoted by many hormone-imbalance supplement sellers and their affiliated lab facilities (a common but questionable business arrangement that can easily create conflict of interest). Not only are saliva sampling and blood sampling methods prone to technical problems; they also cannot provide an integrated measure of daily hormone production. A blood or saliva sample represents only a moment in time, rather than the full picture of multiple hormones’ production, interactions, and level over time, as revealed by Rhein Labs’ 24-hour USHP.

Why Urine Sampling?

Rhein Labs utilizes the scientifically superior assay matrix of a 24-hour urine sample. Why? Because only a urine sample provides the information needed to assess the full range of hormone levels and interactions throughout the full 24-hour cycle. When you combine this advantage with Rhein Labs’ industry-leading analytical and interpretive expertise, you benefit from the most in-depth, cost-effective hormone profiling available today.

Combining this advantage of comprehensive, accurate measurement with Rhein Labs’ industry-leading analysis and interpretation expertise gives healthcare providers and researchers alike a new team member. Only Rhein Labs can offer a research or provider team the most in-depth, cost-effective hormone profiling anywhere.
