What is being analysed?

The amount of oestrogen in the body is being analysed in this test. Oestrogen is a vital hormone primarily produced in the ovaries in females and smaller quantities in males. It plays a crucial role in regulating the menstrual cycle, supporting reproductive function, maintaining bone density, and impacting various other physiological processes.

When is it requested?

Analysis of oestrogen levels is typically requested when assessing reproductive health, investigating fertility issues, monitoring hormone replacement therapy, diagnosing certain medical conditions such as polycystic ovary syndrome (PCOS), evaluating puberty development, and assessing risks for osteoporosis.

When should the analysis be done?

The analysis of oestrogen levels is often conducted during specific phases of the menstrual cycle to obtain accurate results. Additionally, it may be performed at various stages of life or during hormonal therapies to monitor changes and ensure optimal health outcomes.

What sample is required?

A blood sample is typically required for oestrogen analysis. This sample is collected through venipuncture, commonly from a vein in the arm, and then sent to the laboratory for testing.

Is any prior preparation necessary?

In most cases, no special preparation is needed before oestrogen analysis. However, it's advisable to follow any specific instructions provided by the healthcare provider, such as fasting requirements or discontinuation of certain medications that might interfere with the test results.

What are the normal values?

Normal oestrogen levels vary depending on factors such as age, gender, and stage of the menstrual cycle. Generally, in premenopausal women, oestrogen levels fluctuate throughout the menstrual cycle, with peak levels during the mid-follicular phase (around 70-500 pg/mL) and lower levels during the early follicular and luteal phases. In postmenopausal women, oestrogen levels typically range lower, around 10-60 pg/mL.

What do abnormal values suggest?

Abnormal oestrogen levels can indicate various health issues. High levels of oestrogen may suggest conditions such as ovarian tumours, polycystic ovary syndrome (PCOS), or hormone replacement therapy overdose, while low levels may indicate ovarian dysfunction, menopause, or certain eating disorders. Interpretation of results should be done in conjunction with other clinical findings and medical history.
