What Causes High Specific Gravity?

What color is urine when your kidneys are failing?

When kidneys are failing, the increased concentration and accumulation of substances in urine lead to a darker color which may be brown, red or purple.

The color change is due to abnormal protein or sugar, high levels of red and white blood cells, and high numbers of tube-shaped particles called cellular casts..

What does abnormal urine test mean?

A urinalysis is used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes. A urinalysis involves checking the appearance, concentration and content of urine. Abnormal urinalysis results may point to a disease or illness.

What does a specific gravity of 1.025 mean?

Specific gravity is usually 1.010-1.025 (normal range: 1.003-1.030) and highest in the morning. A value >1.025 indicates normal concentrating ability. A value >1.035-1.040 suggests possible contamination, very high levels of glucose, or recently received low-molecular-weight dextran or high-density radiopaque dyes.

Is high specific gravity in urine bad?

Abnormal: A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.

Why do we need specific gravity?

The term “Specific Gravity” (SG) is used to define the weight or density of a liquid as compared to the density of an equal volume of water at a specified temperature. The temperature used for measurement is usually 39.2oF (4oC), because this temperature allows water to assume its maximum density.

What should urine specific gravity be?

The normal range for urine specific gravity is 1.005 to 1.030. Normal value ranges may vary slightly among different laboratories.

What does a high specific gravity indicate?

Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be. High urine specific gravity can indicate that you have extra substances in your urine, such as: glucose.

What does specific gravity tell us?

Urinary specific gravity (SG) is a measure of the concentration of solutes in the urine. It measures the ratio of urine density compared with water density and provides information on the kidney’s ability to concentrate urine. A urinary specific gravity measurement is a routine part of urinalysis.

How do you lower urine specific gravity?

Decreased urine specific gravity may be due to:Damage to kidney tubule cells ( renal tubular necrosis )Diabetes insipidus.Drinking too much fluid.Kidney failure.Low sodium level in the blood.Severe kidney infection (pyelonephritis)

What does a specific gravity of 1.020 mean?

Urine specific gravity is a measure of the ratio of the density of urine to the density of water. Urine specific-gravity measurements normally range from 1.002 to 1.030. 5. The NCAA selected a urine specific-gravity measurement of ≤1.020 to indicate euhydration. 4.

What are the warning signs of kidney trouble?

These include:increased blood pressure.excessive fatigue.sleeping troubles.feet or ankle swelling (which later progresses upward)forgetfulness and trouble concentrating.nausea or vomiting.decreased appetite and unintentional weight loss.muscle twitching or cramps.More items…•

What is the importance of specific gravity?

4.1 Specific gravity is an important property of fluids being related to density and viscosity. Knowing the specific gravity will allow determination of a fluid’s characteristics compared to a standard, usually water, at a specified temperature.
