what is urea,sodium,potassium and other test in urine.what should be its safty level??how to reduce its level?
Urea nitrogen--urine: This test is mainly used to determine a person's protein balance and the amount of dietary protein needed by severely ill patients. It is also used to determine how much protein a person takes in.
Urea is excreted by the kidneys, so excretion of urea can reflect kidney function.
Sodium--urine: The test is often used to determine your hydration status and your kidney's ability to conserve or remove sodium from the urine.
Additional conditions under which the test may be performed:--
* Acute tubular necrosis
* Hepatorenal syndrome
* Medullary cystic kidney disease
* Glomerulonephritis
* High blood pressure (hypertension)
* Prerenal azotemia
Potassium test:This test is routinely done as part of a basic or comprehensive metabolic panel.
Your doctor may order this test to diagnose or monitor kidney disease. The most common cause of high potassium levels is kidney disease.
Because potassium is important to heart function, your doctor may order this test if you have signs of high blood pressure or heart problems. Small changes in potassium levels can have a big effect on the activity of nerves and muscles, especially the heart. Low levels of potassium can lead to an irregular heartbeat or other electrical malfunction of the heart. High levels cause decreased heart muscle activity. Either situation can lead to life-threatening heart problems.
It may also be done if your doctor suspects metabolic acidosis (for example, caused by uncontrolled diabetes) or alkalosis (for example, caused by excess vomiting).
Occasionally, the potassium test may be done in persons who are having an attack of paralysis.
