Dehydroepiandrosterone (DHEA, DHA)

Dehydroepiandrosterone, an intermediate in testosterone biosynthesis, is mainly produced by 17β-hydroxysterol dehydrogenase to produce androstene-3&beta, 17&beta-diol, △5-3&beta,-hydroxyindole dehydrogenase and △5, △4-isomerase produces testosterone, which has a weak androgenic effect and can be detected from the urine, often in the form of sulfate. These are considered to be androgens from the para-renal. The corpus callosum produced in the fetal kidney is 16&alpha in the liver and the like, and after hydroxylation, it becomes estriol in the placenta. Basic Information Specialist classification: urinary examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: The more sensitive the target antigen in a certain range, the higher the sensitivity. Normal value Pee Children <0.35 μmol/24h (<0.1mg/24h). adult Male 0 ~ 8.0μmol / 24h (0 ~ 2.3mg / 24h). Female 0 ~ 4.2μmol / 24h (0 ~ 1.2mg / 24h). serum Children 3.5 ~ 10.4nmol / 24h (1.0 ~ 3.0ng / ml). adult Male 5.9 ~ 44.6nmol / 24h (1.7 ~ 4.2ng / ml). Female 6.9 ~ 18.0nmol / 24h (2.0 ~ 5.2ng / ml). 1.0 to 15.6 nmol/24 h (0.3 to 4.5 ng/ml) after menopause. Clinical significance (1) Elevation of Cushing's syndrome, adrenal cancer, 3β-hydroxydehydrogenase deficiency, 21-hydroxylase deficiency, 11β-hydroxylase deficiency, and the like. (2) reduce Addison's disease, secondary adrenal insufficiency, congenital adrenal hyperplasia, 17α-hydroxylase deficiency, Cushing syndrome caused by adrenal adenoma, steroid treatment. High results may be diseases: Adrenal tumors precautions The addition of 3H-DHA14000dpm/50μl herein is, for example, generally determined according to experimental conditions. However, the more sensitive the target antigen is, the higher the sensitivity is. Inspection process Determination of gonadotropins. Not suitable for the crowd Generally no taboos. Adverse reactions and risks Generally not.
