Normal Results
The normal range for urine specific gravity is 1.005 to 1.030. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results.
What does SG 1.020 in urine mean?
Ideally, urine specific gravity results will fall between 1.002 and 1.030 if your kidneys are functioning normally. Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be.
What does SG 1.005 mean?
Specific gravity. Normal: 1.005–1.030 footnote1. 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.
What does a specific gravity of 1.002 mean?
Specific Gravity (1.002 – 1.035)
Specific Gravity measures the ability of the kidney to concentrate or dilute the urine and is directly proportional to urine osmolality (solute concentration). Specific gravity between 1.002 and 1.035 on a random sample is normal IF kidney function is normal.
What causes low urine osmolality?
Several conditions may cause low urine osmolality, including: excessive fluid intake, or over-hydration. kidney failure. renal tubular necrosis.
Is urine specific gravity of 1.020 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 does low urine specific gravity mean?
Interpretation. 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.
What does a urine 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 specific gravity 1.015 normal?
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.
What is a normal pH for urine?
The normal values range from pH 4.6 to 8.0. The examples above are common measurements for results of these tests. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples.
Will drinking water reduce protein in urine?
Drinking water will not treat the cause of protein in your urine unless you are dehydrated. Drinking water will dilute your urine (water down the amount of protein and everything else in your urine), but will not stop the cause of your kidneys leaking protein.
What color is your urine if you have kidney problems?
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 a specific gravity of 1.015 mean?
Specific gravity and disease
A specific gravity greater than 1.035 is consistent with frank dehydration. In neonates, normal urine specific gravity is 1.003. Hypovolemic patients usually have a specific gravity >1.015.
How do you increase urine specific gravity?
Glucose, protein, or dyes used in diagnostic tests excreted into the urine increase the specific gravity.
What lab values indicate diabetes insipidus?
Laboratory Findings
- Plasma sodium concentration that is less than 137 meq/L associated with a low urine osmolality indicates water overload due to primary polydipsia.
- Plasma sodium concentration greater than 142 meq/L, due to water loss indicates diabetes insipidus diabetes insipidus.
What is the specific gravity in diabetes insipidus?
A urinary specific gravity of 1.005 or less and a urinary osmolality of less than 200 mOsm/kg are the hallmark of DI.
What does high density in urine mean?
Urine density is highly affected by the amount of water consumed prior to specimen collection. Urine density above 1.010 and even above 1.030 usually indicates that the kidney has retained its ability to concentrate urine. A density below 1.003 may indicate renal problems, but also excessive water consumption.
What does low osmolality indicate?
“Osmolality” refers to the concentration of dissolved particles of chemicals and minerals — such as sodium and other electrolytes — in your serum. Higher osmolality means you have more particles in your serum. Lower osmolality means the particles are more diluted.
What is low urine osmolality?
A urine osmolality value of less than 100 mOsm/kg indicates complete and appropriate suppression of antidiuretic hormone secretion. A urine sodium level less than 20 mmol/L is indicative of hypovolemia, whereas a level greater than 40 mmol/L is suggestive of the syndrome of inappropriate antidiuretic hormone secretion.
What does urine osmolality indicate?
Urine osmolality is used to measure the number of dissolved particles per unit of water in the urine. As a measure of urine concentration, it is more accurate than specific gravity. Urine osmolality is useful in diagnosing disorders of urinary concentration such diabetes insipidous and in assessing hydration status.
Is specific gravity of 1.000 normal?
Which are considered normal results? The normal range for urine specific gravity is: Adults: 1.005 – 1.030.
What is the normal range of pus cells in urine?
The normal range of pus cells in urine is 0-5/hpf , however up to 10 pus cells may be present without any definite infection. If you have any symptoms of a urine infection, you should get a urine culture done.
