Understanding Estrone Levels: What You Need to Know

Estrone (E1) is a type of estrogen, a female sex hormone produced by the ovaries. It plays a crucial role in the development and maintenance of female reproductive organs, as well as in the growth and maintenance of bones. Estrone is also involved in the regulation of the menstrual cycle and pregnancy.
Estrone levels can be used to diagnose and monitor certain medical conditions, such as polycystic ovary syndrome (PCOS), endometriosis, and uterine fibroids. High levels of estrone may indicate an imbalance in hormone production, which can lead to symptoms such as irregular periods, weight gain, and mood changes. Low levels of estrone may indicate a decrease in ovarian function, which can lead to symptoms such as menopause or infertility.
Estrone can be measured in the blood or urine, depending on the specific test ordered by your healthcare provider. The normal range for estrone levels varies depending on age and other factors, but generally, the following ranges are considered normal:

* Blood: 30-400 pg/mL (picograms per milliliter)
* Urine: 20-100 ng/dL (nanograms per deciliter)

It's important to note that estrone levels can fluctuate throughout the menstrual cycle, so your healthcare provider may recommend that you have your blood or urine tested on a specific day of your cycle to get an accurate reading. Additionally, certain medications and medical conditions can affect estrone levels, so it's important to discuss any medications you are taking or any symptoms you are experiencing with your healthcare provider when interpreting your test results.
