A potassium blood test measures the amount of potassium in your blood. Potassium is a type of electrolyte . Electrolytes are electrically charged minerals that help control the amount of fluids and the balance of acids and bases (pH balance) in your body. They also help control muscle and nerve activity and perform other important functions.

Indicadores
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 .
Pruebas
Point-of-care measurement of oxygenation, ventilation, acid-base status, and electrolytes in critically ill patients.
Indicadores
A cardiac glycoside. Digoxin inhibits the sodium potassium adenosine triphosphatase (ATPase) pump, thereby increasing intracellular calcium and enhancing cardiac contractility. This agent also acts directly on the atrioventricular node to suppress conduction, thereby slowing conduction velocity. Apparently due to its effects on intracellular calcium concentrations, digoxin induces apoptosis of tumor cells via a pathway involving mitochondrial cytochrome c and caspases 8 and 3. (NCI04)

Electrolytes are minerals that have an electrical charge when they are dissolved in water or body fluids. You have electrolytes in your blood, urine, tissues, and other body fluids. They are important because they help:

A magnesium blood test measures the amount of magnesium in a sample of your blood. Magnesium is a mineral that you get from many kinds of foods you eat. Some examples include nuts, seeds, beans, fortified breakfast cereals, green leafy vegetables, and milk.
Indicadores
An element with atomic symbol K, atomic number 19, and atomic weight 39.10.
Pruebas
The determination of the ratio of potassium compared to creatinine present in a sample. The measurement may be expressed as a ratio or percentage.
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.
