It is the major Mineralocorticoid produced by the adrenal cortex, 200 µg/day.Other examples of endogenous mineralocorticoids are progesterone and deoxycorticosterone.Aldosterone regulates sodium and potassium.It is produced in the zona glomerulosa of the adrenal cortex.The primary example of mineralocorticoid is aldosterone.Weight approximately = 4 grams (regardless of age and sex).Īndrogens are converted into estrogen Mineralocorticoid.The adrenal medulla is derived from the ectoderm.These hormones maintain the homeostasis of the body.The adrenal cortex is derived from the mesoderm.Adrenal glands consist of the following:.Pathophysiology of Adrenal Gland Hormones: Adrenal glands Transport the plasma on ice to the lab.Cortisol’s highest level is 8 AM and >50% less at 8 PM.THE aldosterone AM sample is higher than PM.Avoid herbal medicines and any medication which interferes with the test.Reduce stress before performing this test.Precautions before performing the Adrenal gland tests: A urine 24-hour sample is collected with the addition of boric acid.The serum needs to be frozen immediately after collection.For Estrogen can be estimated in the serum.Urine is collected for 24 hours with boric acid, and during collection, it is refrigerated.The patient must be upright for 2 hours before the sample is taken.For aldosterone test can be done on plasma ( heparin, EDTA, or citrate).The serum is stable for 2 days at 2 to 8 ☌.Urine for 24 hours is collected with the addition of boric acid.Add 6 M HCl and Refrigerate during collection. Transport this plasma on the ice and centrifuge at 4 C within 30 minutes and separate the plasma.For catecholamines (Epinephrine and Norepinephrine), plasma in heparin or EDTA is needed.Adrenal Gland Hormones Sample for Adrenal Gland Hormones
