Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Estrone (E1)
Estrone (E1) is a weaker estrogen that may influence body composition and recovery in athletes. As it is primarily produced in fat tissue, levels could reflect energy balance and training status. Your healthcare provider can help contextualise your results.
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 estrone (E1) in your blood. Estrone is produced by fat tissue, the adrenal glands, and the ovaries. After menopause it becomes the primary circulating estrogen. Your healthcare provider may use this result to assess your overall hormonal status.
Why It Matters
For athletes, estrone levels may reflect body fat percentage and energy availability. Low levels could suggest relative energy deficiency, while elevated levels might indicate excess adipose tissue. Discuss your results with a healthcare provider to optimise your training approach.
When to Test
Your healthcare provider may recommend estrone testing during menopause evaluation, when investigating unexplained weight changes, or as part of a comprehensive hormone panel. Testing could also be suggested for monitoring hormone replacement therapy effectiveness. Consult your provider for personalised guidance.

Lifestyle Tips
Maintaining a healthy body weight may help regulate estrone levels, as fat tissue is a primary production site. Regular exercise, a balanced diet, and limiting alcohol consumption could support healthy estrogen balance. Always consult your healthcare provider before making significant changes.
