Specific Gravity, Urine
Specific gravity reflects how concentrated the urine is, which mostly depends on hydration.
Labwise reads the PDF or a photo of your lab report on your iPhone and explains every test like this page does. Nothing leaves your phone.
What Specific Gravity, Urine measures
Specific gravity reflects how concentrated the urine is, which mostly depends on hydration.
If your Specific Gravity, Urine is low
Dilute urine is commonly associated with high fluid intake or reduced concentrating ability.
Commonly associated with
- High fluid intake
- Diuretics
- Kidney concentrating ability
If your Specific Gravity, Urine is high
Concentrated urine is commonly associated with dehydration or a first-morning sample.
Commonly associated with
- Dehydration
- First-morning sample
- Glucose or contrast in the urine
Typical reference range
| Group | Typical range |
|---|---|
| Adults | 1.005 – 1.03 |
Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.
If it is within range
Your urine concentration is within the typical range.
