A mineralocorticoid hormone produced by aldosterone synthase (CYP11B2) in the zona glomerulosa of the adrenal cortex. Aldosterone binds to mineralocorticoid receptors (MR; NR3C2) and MR-aldosterone complexes regulate the expression of genes involved in the retention of sodium, the secretion of potassium, and water reabsorption, all of which may result increased blood pressure.
Pruebas
An aldosterone test measures the amount of aldosterone (ALD) in your blood or urine (pee). ALD is a hormone made by your adrenal glands, two small glands that sit above your kidneys. ALD helps keep your blood pressure stable by helping to balance the levels of two electrolytes in your blood, sodium and potassium .

Indicadores
An animal sterol found in the body tissues (and blood plasma) of vertebrates. It can be found in large concentrations within the liver, spinal cord, and brain. Cholesterol is an important component of the membranes of cells, providing stability. It is the major precursor for the synthesis of vitamin D, of the various steroid hormones, including cortisol, cortisone, and aldosterone in the adrenal glands, and of the sex hormones progesterone, estrogen, and testosterone. Cholesterol also has an important role for the brain synapses as well as in the immune system. In conditions featuring elevated low density lipoproteins (LDL), cholesterol often forms plaque deposits in the walls of arteries, a condition known as atherosclerosis, which is a major contributor to coronary heart disease and other forms of cardiovascular disease.
Pruebas
This test measures the level of renin in your blood. Renin is an enzyme, a protein that speeds up certain chemical reactions in your body. It's made by your kidneys. When your blood pressure or sodium decreases or your potassium increases, your kidneys release renin. That's because renin also acts as a hormone (a chemical messenger in your bloodstream that controls the actions of certain cells or organs) to help control your blood pressure.
