One thing your healthcare provider may check for in your urine sample test, or urinalysis, is specific gravity. A urine specific gravity test compares the density of urine to the density of water. This quick test can help determine how well your kidneys are diluting your urine.
Is specific gravity 1.025 normal?
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.
What is a normal specific gravity level in urine?
Normal Results Urine osmolality is a more specific test for urine concentration. The urine specific gravity test is easier and more convenient, and is usually part of a routine urinalysis . The urine osmolality test may not be needed. The normal range for urine specific gravity is 1.005 to 1.030.
What does a specific gravity of 1.020 mean?
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 high specific gravity mean?
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.
What is a low specific gravity?
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 is my urine SG high?
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 pH of 6.5 in urine mean?
The American Association for Clinical Chemistry says the normal urine pH range is between 4.5 and 8. Any pH higher than 8 is basic or alkaline, and any under 6 is acidic.
What does SG 1.030 mean?
What does a urine specific gravity of less than 1.005 mean?
Specific gravity will decrease when the water content is high and the dissolved particles are low (less concentrated). Low specific gravity (<1.005) is characteristic of diabetes insipidus, nephrogenic diabetes insipidus, acute tubular necrosis, or pyelonephritis.
How do I read my urine test results?
Normal values are as follows:
- Color – Yellow (light/pale to dark/deep amber)
- Clarity/turbidity – Clear or cloudy.
- pH – 4.5-8.
- Specific gravity – 1.005-1.025.
- Glucose – ≤130 mg/d.
- Ketones – None.
- Nitrites – Negative.
- Leukocyte esterase – Negative.
What causes elevated specific gravity in urine?
The first and most common reason for an increase in urine specific gravity is dehydration. The second reason for a high specific gravity is an increased secretion of anti-diuretic hormone (ADH). ADH causes increased tubular water re-absorption and decreased urine volume.
What are the best urine test strips?

High specific gravity suggests that the urine is too concentrated. Conditions that cause high specific gravity include: Excess substances in the urine can also cause high specific gravity. The doctor may perform additional urine testing, including urinalysis, urine culture, urine osmolality, urine pH, or ketone testing.
What does it mean when urine has a high specific gravity?
High urine specific gravity can be an indication that you have extra substances in your urine—these substances could be glucose, bilirubin, red blood cells, white blood cells, crystals, bacteria, or even protein. Some conditions allow proteins to pass through the filters in kidneys, producing protein in the urine.
How do you increase specific gravity of urine?
Urine Specific Gravity. The first and most common reason for an increase in urine specific gravity is dehydration. The second reason for a high specific gravity is an increased secretion of anti-diuretic hormone (ADH). ADH causes increased tubular water re-absorption and decreased urine volume.
