Estrone and Creatinine, Urine and Stool
This test measures estrone, an estrogen, and creatinine in urine and stool samples. The results may help evaluate estrogen production or hormone balance.
["Estrone and creatinine results can provide information about estrogen activity and help account for differences in sample concentration."]

What is this test?
Estrone is a form of estrogen, a hormone involved in female reproductive development and other hormonal functions. Creatinine is a breakdown product that is often measured alongside hormones to help account for variations in urine or stool concentration.
Why might I need this test?
A clinician may order this test when evaluating estrogen production, hormonal balance, or changes related to reproductive or endocrine conditions. The reason for testing and the way the results are interpreted depend on the symptoms, medical history, and specimen used.
How is the test performed?
The laboratory analyzes urine and stool samples for estrone and creatinine using validated testing methods. The report identifies the specimen type and the amount or concentration of each substance measured.
How do I prepare for the test?
Follow the collection instructions provided by the laboratory or your clinician. Urine and stool should be collected in the designated clean containers, and the collection time, date, and any medication or supplement use may need to be reported.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
An elevated or reduced estrone result may reflect differences in estrogen production, metabolism, menstrual or reproductive status, medications, or other hormonal influences. Creatinine can help show how concentrated the specimen is, but an abnormal value in urine or stool is interpreted in the context of the specific test and the person's symptoms. Results should not be interpreted independently without guidance from a qualified clinician.
