Estrone, by Mass Spectrometry
Also known as: ESTRNE TMS
Use
The Estrone, by Mass Spectrometry test is used to measure the levels of estrone, a type of estrogen, in the blood. It is particularly useful in the evaluation of estrogen status in patients and can be valuable for assessing conditions related to abnormal estrogen production, metabolism, or response. This test helps in understanding hormonal imbalances and is typically used in clinical settings to provide insights into various conditions such as ovarian function, menopause, and certain forms of cancer.
Special Instructions
This test is rarely indicated in clinical practice. The preferred test for the measurement of estrone is the Estrogens, Fractionated, by Mass Spectrometry test. It's important to separate serum or plasma from cells within 2 hours of collection and transfer it appropriately for accurate results.
Limitations
The test is not cleared or approved by the US Food and Drug Administration and hence may not meet the regulatory standards of an FDA-cleared test. It is performed in a CLIA-certified laboratory and is intended for clinical purposes. The test results can be influenced by improper specimen handling or storage, and external factors such as interfering substances can affect the accuracy of estrone measurement.
