Urine specific gravity (SG) (or, more correctly, its osmolarity) is the only indicator of renal function in the urinalysis. Urinary specific gravity reflects the ability of the kidney to concentrate urine and is therefore a useful indicator of renal function.

What does specific gravity in urine indicate?
Urine specific gravity is a laboratory test that shows the concentration of all chemical particles in the urine.
What happens when specific gravity of urine increase?
Increases in specific gravity (hypersthenuria, i.e. increased concentration of solutes in the urine) may be associated with dehydration, diarrhea, emesis, excessive sweating, urinary tract/bladder infection, glucosuria, renal artery stenosis, hepatorenal syndrome, decreased blood flow to the kidney (especially as a …
Does kidney disease cause high specific gravity?
High specific gravity indicates dehydration. A fixed specific gravity of about 1.010 indicates renal inability to concentrate urine, suggesting progression to end-stage renal disease (ESRD).
Which physical characteristics of urine is not usually reported on the urinalysis report form?
Usually, glucose, ketones, protein, and bilirubin are not detectable in urine. The following are not normally found in urine: Hemoglobin. Nitrites.
Is urine specific gravity 1.010 normal?
Normal results in adults generally range from 1.010 to 1.020. Abnormal results are generally those below 1.010 or above 1.020. In patients with certain kidney diseases, USG doesn’t vary with fluid intake and is called a fixed specific gravity.
What would a specific gravity of 1.030 indicate to you?
Your urine specific gravity is generally considered normal in the ranges of 1.005 to 1.030. If you drink a lot of water, 1.001 may be normal. If you avoid drinking fluids, levels higher than 1.030 may be normal.
Why is urine specific gravity low in renal failure?
The third reason for low specific gravity is renal failure, which results in a fixed specific gravity between 1.007 and 1.010. In renal failure, the remaining functional nephrons undergo compensatory structural and hypertrophic changes. These compensatory changes result in urine that is almost isotonic with plasma.
What happens if specific gravity of urine is low?
Low specific gravity (SG) (1.001-1.003) may indicate the presence of diabetes insipidus, a disease caused by impaired functioning of antidiuretic hormone (ADH). Low SG also can occur in patients with glomerulonephritis, pyelonephritis, and other renal abnormalities.
Why does morning urine tend to have a high specific gravity?
The first urine of the morning is most likely to have the highest solute concentration. USG will vary based on diet moisture content, amount of water consumed, excess dietary solutes requiring renal excretion, renal function, and hydration status (see Chapter 15, Approach to Polyuria and Polydipsia).
What 3 characteristics are routinely noted in the physical examination of urine?
Physical characteristics that can be applied to urine include color, turbidity (transparency), smell (odor), pH (acidity – alkalinity) and density.
How do you know when your bladder needs to be emptied?
You urinate more than eight times a day and often feel like you have to urinate urgently. You have some trouble starting to urinate before urine comes out. When you urinate, the stream of urine is erratic, weak, or stops before you feel finished. Even after you urinate, you have the urge to go again shortly after.
What organs make up the urinary system?
The urinary system’s function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra. The body takes nutrients from food and converts them to energy.
What are the 7 functions of the kidney?
Kidney and its Function
- Removal of waste products.
- Removal of excess fluid.
- Balance minerals and chemicals.
- Control of blood pressure.
- Red blood cells production.
- To maintain healthy bones.
What are the 7 functions of the urinary system?
Balance the body’s fluids. Balance a variety of electrolytes. Release hormones to control blood pressure. Release a hormone to control red blood cell production.
What is the function of the kidneys in the urinary system?
The kidneys remove waste from the blood through tiny filtering units called nephrons. Each nephron is made up of a ball of small blood capillaries, called a glomerulus. There is also a small tube called a renal tubule, which drains the urine and joins other tubules carrying the urine out of the kidney to the ureter.
What are the 3 main functions of the kidney?
The kidneys are powerful chemical factories that perform the following functions:
- remove waste products from the body.
- remove drugs from the body.
- balance the body’s fluids.
- release hormones that regulate blood pressure.
- produce an active form of vitamin D that promotes strong, healthy bones.
What are two primary functions of the kidney?
What are two primary functions of the kidney? excretion and regulation.
What are the functions of kidney Class 10?
maintaining overall fluid balance. regulating and filtering minerals from blood. filtering waste materials from food, medications, and toxic substances.

What is the function of urinary bladder Class 7?
The function of the urinary bladder is to store urine. The function of the urinary bladder is to store urine.
What is a function of the kidneys quizlet?
The primary function of the kidneys is to filter blood to produce urine.
What are the 3 main functions of the kidneys quizlet?

What is the main function of the kidneys quizlet Chapter 15?
Kidneys, ureters, urinary bladder, and urethra. What are the functions of the kidneys? Filter the blood, remove wastes, excrete the wastes in urine.
What is the kidneys most important function quizlet?
The most important function of the kidney is the homeostatic regulation of the water and ion content of the blood, also called salt and water balance or fluid and electrolyte balance.
What is the most important function of kidney?
Your kidneys remove wastes and extra fluid from your body. Your kidneys also remove acid that is produced by the cells of your body and maintain a healthy balance of water, salts, and minerals—such as sodium, calcium, phosphorus, and potassium—in your blood.
What are the four main functions of the kidneys quizlet?
Functions of the Kidneys
- Regulation of extracellular fluid volume and blood pressure.
- Regulation of osmolarity.
