Area of Science:
- Biochemistry
- Analytical Chemistry
- Endocrinology
Background:
- Dehydroepiandrosterone (DHA) is a crucial steroid hormone.
- Accurate measurement of urinary DHA is important for clinical diagnostics.
Purpose of the Study:
- To describe a novel method for quantifying urinary dehydroepiandrosterone (DHA).
- To validate the method's suitability for routine clinical use.
Main Methods:
- Urinary samples were extracted using ethylacetate.
- Solvolysis was performed on the extracted samples.
- Colorimetric determination was achieved using 3beta-hydroxysteroid dehydrogenase.
Main Results:
- The developed method demonstrated sufficient accuracy and reliability.
- Comparison with gas-liquid chromatography confirmed the method's validity.
- Recovery tests indicated consistent and precise results.
Conclusions:
