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.

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.
Symptoms
Low Levels
Some people may experience fatigue, low blood pressure, or salt cravings when 17-OH Progesterone levels are below the expected range. These symptoms could suggest insufficient adrenal hormone production. A healthcare provider can help determine the cause.
High Levels
Some people may experience acne, excess body hair, or irregular menstrual cycles when 17-OH Progesterone levels are elevated. High levels could suggest an enzyme deficiency in the adrenal pathway. Discuss results with your healthcare provider.
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.
