When to Seek Prompt Care

Seek urgent medical advice if abnormal results are accompanied by severe thirst, confusion, dizziness, rapid heart rate, or inability to keep fluids down.

What It Measures

This lab test checks how many tiny bits of stuff are in your pee. It shows how thick or thin your pee is compared to water. This helps us see how well your kidneys are making your pee more watery or more concentrated.

Why It's Ordered

Your doctor orders this test to see how much water is in your body. It also checks how well your kidneys are working. This test can help find problems like a type of diabetes or other kidney issues.

Reference Range

Typical urine specific gravity ranges from 1.005 to 1.030, but these ranges can vary by lab and depend on factors like hydration, age, and other medical conditions.
