Specific Gravity Of Urine Test

Basically the test compares the specific gravity. Our specific gravity urine test strip the test is a measurement of the ion concentration of the urine. The specific gravity of urine is expressed or measured in grams milliliter g ml.

Urinary specific gravity sg is a measure of the concentration of solutes in the urine.

Specific gravity of urine test. A higher than normal concentration often is a result of not drinking enough fluids. Decreased specific gravity hyposthenuria i e. Urine specific gravity is a laboratory test that measures the concentration of all chemical particles in the urine. Specific gravity results above 1 010 can indicate mild dehydration.

In a cationic environment protons released by a complexing agent will cause the indicator bromothymol blue to change color from blue green to yellow in urine of increasing ion concentrations. High specific gravity 1 035 occurs in nephrotic syndrome dehydration acute glomerulonephritis heart failure liver failure or shock. Decreased concentration of solutes in urine may be associated with renal failure pyelonephritis diabetes insipidus acute tubular necrosis interstitial nephritis and. In neonates normal urine specific gravity is 1 003.

The specific gravity normal range is often found to vary. Ideally urine specific gravity results will fall between 1 002 and 1 030 if your kidneys are functioning normally. It allows doctors to see the concentration of all particles that are present in the urine. A urine specific gravity test or urine density may be performed if a doctor suspects you are dehydrated or have a condition such as heart failure.

Hypovolemic patients usually have a specific gravity 1 015. A measure of concentration or specific gravity shows how concentrated particles are in your urine. It measures the ratio of urine density compared with water density and provides information on the kidney s. A urine specific gravity test compares the density of urine with the density of water.

However 1 010 to 1 035 g ml or 1 005 to 1 030 g ml are considered as the normal ranges of this test. Fixed specific gravity in which values remain 1 010 regardless of fluid intake occurs in chronic glomerulonephritis with severe renal damage.
