Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
17-OH Progesterone
17-OH Progesterone is a precursor hormone involved in cortisol and androgen synthesis. For athletes, this marker may provide insight into how your body manages stress hormones and supports recovery and performance.
Reference Ranges
Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.
What It Measures
This test measures the level of 17-hydroxyprogesterone in your blood. Elevated or reduced levels may indicate how effectively your adrenal glands and gonads are producing cortisol and sex hormones from this essential precursor.
Why It Matters
For athletes, 17-OH Progesterone levels may reflect adrenal stress response and recovery capacity. Monitoring this marker could help identify imbalances that might affect training adaptation. Discuss results with your sports medicine provider.
When to Test
Testing may be recommended when symptoms of adrenal dysfunction or hormonal imbalance are present. Your healthcare provider might suggest early morning testing, as levels follow a diurnal pattern and are typically highest in the morning.

Lifestyle Tips
Managing stress through regular exercise, adequate sleep, and relaxation techniques may support healthy adrenal function. A balanced diet rich in vitamins and minerals could also contribute to optimal hormone production. Always consult your healthcare provider for guidance.
