Urinary Electrolytes

The Potassium Random, Urine test measures the amount of potassium excreted in the urine sample taken at any random time of the day. Potassium is predominantly present inside cells throughout the body, and its level is regulated by the kidneys. Under normal circumstances, the body absorbs the required amount of potassium from the dietary sources and eliminates the remaining quantity through urine. Potassium level is normally maintained by the hormone aldosterone. Aldosterone acts on the nephrons present in the kidneys and activates the sodium-potassium pump that helps the body reabsorb sodium and excrete potassium. This aids in maintaining a normal and steady potassium level in the body. 

The Chloride Random, Urine test measures the amount of chloride in the urine sample at any time of the day. Chloride is absorbed in the small intestine and remains in the body’s fluids and blood. Any excess amount is excreted in urine. The body gets most of the chloride through dietary salt (sodium chloride or NaCl) and a small amount through other food items. Chloride is usually bound to sodium, and therefore the amount in blood tends to coincide with sodium levels but may also change without any changes in sodium levels when there are problems with the body's pH. Usually, the normal blood chloride level remains steady with a slight fall after meals (because the stomach produces hydrochloric acid using chloride from the blood after we eat food).

The Sodium Random Urine test is used to measure the amount of sodium excreted in your urine at any point in time during the day. Sodium is present in all body fluids and is found in the highest concentration in the extracellular fluid. You need an adequate amount of sodium to balance other minerals that are in your body. Sodium is also needed to carry nutrients to different parts of your body. Your body absorbs the required amount of sodium through dietary salts and the remaining is eliminated through the kidneys. This test helps your doctor to find out if you have kidney damage or another condition that can be alarming for your health.
