Overview of your Kidney's

Kidney function test is a term for a variety of individual tests and also procedures which can be done to evaluate how well your kidneys are functioning.

The kidneys are well known for the body's natural filtration system, which will perform many vital functions, including removing few metabolic waste products from the bloodstream, regulating the body's water balance, and also maintaining the pH of the body's fluids. Approximately one and a half quarts of body blood per minute are circulated through the kidneys, where waste chemicals are filtered out and eliminated from the human body in the form of urine. Kidney function tests will help to determine if the kidneys are performing their tasks adequately.


Many of the conditions can affect the ability of your kidneys to carry out their vital functions. Some will lead to a rapid decline in their kidney function; others lead to a gradual decline in function. Both will result in a buildup of toxic waste substances in the blood. These tests are done on urine samples, as well as on blood samples.

Urine tests:

There are a variety of urine tests which assess kidney function. A simple, inexpensive screening test, is also called a routine urinalysis, is often the first test administered if kidney problems are suspected. A casually collected urine sample is well physically for few particular things like odor, appearance, color, and concentration, chemically for substances such as protein, glucose, and pH (acidity/ alkalinity); and microscopically for the presence of few cellular elements (red blood cells, white blood cells, and epithelial cells), bacteria, crystals, and casts (structures formed by the deposit of protein, cells, and other substances in the kidneys' tubules). If the results will indicate a possibility of the disease one or more of the following few additional tests is generally performed to more specifically diagnose the cause and the level of a decline in kidney function.

Creatinine clearance test:

This test will evaluate how efficiently the kidneys clear a substance called as creatinine from the blood. Creatinine, a waste product of your muscle energy metabolism, it is produced at a limited constant rate which is proportional to the muscle mass of the individual. Because the human body generally does not recycle it, all of the creatinine filtered by the kidneys in a given amount of time is excreted in the urine, making creatinine clearance a very particular measurement of kidney function. Apart from this fasting blood sugar level tests are also recommended to diagnose diabetes. As the fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal.

Urea clearance test:

Urea clearance test is a waste product which is created by protein metabolism and excreted in the urine. The urea clearance test requires a blood sample to measure the particular amount of urea in your bloodstream and two urine specimens, collected one hour apart, to determine the amount of urea which is filtered, or cleared, by the kidneys into the urine.

Urine protein test:

The persistent presence of significant amounts of protein in the urine, then, is an essential indicator of the kidney disease.
