Urine 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.
Sample Required:
The random urine sample can be taken.
Why Get Tested:
- Urine analysis is part of the routine diagnostic profile.
- This gives an idea about the kidney Diseases.
- This also gives an idea about the hydration status.
Normal Values:
- 1.005 to 1.030
Increased specific gravity is seen in:
- Dehydration.
- Decreased renal blood flow.
- Diabetes mellitus.
- Excessive water loss in fever, vomiting, and diarrhea.
- Toxemia of pregnancy.
- Congestive heart failure.
- Proteinuria.
- water restriction.
Decreased specific gravity is seen in:
- Diabetes insipidus.
- Early chronic failure.
- Severe renal damage.
- Hypertension.
- Overhydration.
- Diuresis.
Test Procedure:
A technician may use dipstick method. The dipstick will change color according to the content of the urine.
