Urine specific gravity
| Urine specific gravity | |
|---|---|
| Reading of a urine specific gravity of ~1.024 via a handheld refractometer. SG measurement is taken by reading the boundary between the dark and light fields against the graduations on the left column. | |
| Purpose | evaluation of kidney function | 
Specific gravity, in the context of clinical pathology, is a urinalysis parameter commonly used in the evaluation of kidney function and can aid in the diagnosis of various renal diseases.
