Why update test information and related content for testosterone and estrogen tests?

Accurate measurement of testosterone and estrogen is dependent on many factors, such as hormone concentration or phase of hormone therapy. These factors are important to consider when choosing related endocrine tests and can make it difficult to select the correct test.

By providing additional information in test names, ordering recommendations, and chartable interpretive comments (including clinical scenario, methods, expected hormone concentrations, and recommended alternative tests), these updates will reduce confusion surrounding test selection and aid clinicians in choosing the appropriate test.

These updates provide several benefits:

• Reduce costs and save time by improving test utilization patterns
• Provide efficient, high-quality testing for diverse clinical scenarios
• Improve care for any patient on hormone therapy
