DUTCH Sex Hormones and Metabolites with Organic Acids Test (OATs)
Precision Analytical (DUTCH)
Sample type: Urine
Requires fasting: No
At home test
Details
When it comes to getting baseline sex hormone measurements or monitoring levels during hormone replacement therapy, this test makes it easy for practitioners and patients. By utilizing a liquid chromatography mass-spectrometry method, this unique sex hormone metabolite profile can provide more accurate vaginal hormone and oral progesterone monitoring. This panel includes the Organic Acids Test (OATs), which provides a comprehensive view of possible nutrition, hormone, and metabolite imbalances or deficiencies that can influence overall health, energy, and quality of life.
