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 form of estrogen that becomes increasingly important with age. Produced mainly in fat tissue, it reflects your body's estrogen activity after reproductive years. Monitoring E1 may help your healthcare provider assess your overall hormonal health.
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
Estrone becomes the primary estrogen as other forms decline with age. Balanced levels may support bone health, metabolic function, and overall wellbeing. Your healthcare provider can help you understand how your estrone levels fit into your broader health picture.
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.
