Normal Results In general, normal values for specific gravity are as follows: 1.005 to 1.030 (normal specific gravity) 1.001 after drinking excessive amounts of water. More than 1.030 after avoiding fluids. Concentrated after receiving ADH.
Normal Results
The normal range for urine specific gravity is 1.005 to 1.030. Normal value ranges may vary slightly among different laboratories.
Specific gravity. Normal: 1.005–1.030 footnote 1. 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.
Decreased urine specific gravity may be due to: Damage to kidney tubule cells ( renal tubular necrosis ) Diabetes insipidus. Drinking too much fluid.
Low specific gravity suggests that urine is too diluted. The person may be drinking too much fluid or have a condition that makes them thirsty. Conditions that cause low specific gravity include: diabetes insipidus.
A low urine specific gravity test indicates that the concentration of your urine is close to that of water. This is usually not a cause for concern and likely indicates that you are very hydrated. It may also indicate diabetes or damage to the kidneys / kidney failure.
The normal specific gravity ranges from person to person. 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.
Dehydration results in a more concentrated urine (SG over 1.035–1.055).
ADJUST BY ADDING SUGAR
Add corn sugar/invert sugar/ to increase the gravity. To calculate the amount needed, take an initial gravity reading, then subtract that from the specific gravity you wish to begin with. The difference will determine approximately how much sugar to add (use table below).
Urine Specific Gravity (USG) measurement
The specific gravity of urine that has not been concentrated or diluted is between 1.008 and 1.012. If kidneys are concentrating the urine the USG will be greater than 1.015. Concentrated urine shows that the kidneys are functioning in this task.
URINE SPECIFIC GRAVITY (USG) measures the concentration of particles in urine and the density of urine compared with the density of water. Measuring USG is an easy and convenient way to gauge a patient's hydration status as well as the functional ability of his kidneys.
Glucose, protein, or dyes used in diagnostic tests excreted into the urine increase the specific gravity.
If your urine is clear and you're not on a water pill or drinking a lot of water, it may signal an underlying kidney problem or possibly diabetes.
A number of renal or extra-renal infections which may be associated with urinary tract infections manifest themselves by a significant decrease of urine specific gravity <1,015.
1.005 to 1.030 (normal specific gravity) 1.001 after drinking excessive amounts of water. More than 1.030 after avoiding fluids. Concentrated after receiving ADH.
Diabetes insipidus (DI) is characterized by polydipsia and polyuria with a dilute urine having a specific gravity less than 1.010, hypernatremia, and dehydration.
When you have not drank enough fluids your kidneys try to save as much water as they can and cause your urine to be darker in colour (more concentrated). Dark yellow urine is a sign that you are dehydrated and that you must drink more fluids to prevent dehydration.
Urinalysis. Tests done on your urine can help show whether you're dehydrated and to what degree. They also can check for signs of a bladder infection.
As the volume of electrolyte expands, specific gravity readings are lowered and, conversely, specific gravity increases with colder temperatures.
Thus, in uncontrolled diabetic patients, the urine specific gravity might reach 1.045 to 1.050 as a result of the above-mentioned loss of glucose in the urine.
Urine specific gravity (USG) has been used to estimate hydration status in athletes on the field, with increasing levels of hypohydration indicated by higher USG measurements (eg, greater than 1.020).
Chemistry and Physics of Fire and Liquid Fuels
The specific gravity of a liquid is the relative weight of that liquid compared to an equal volume of water. The specific gravity of water is de facto 1.
Elevated urine-specific gravity values can occur as a result of diet, heavy daily exercise, high lean body mass, and high protein turnover.
