Albumin/Creatinine Ratio levels: what's normal, high and low
Urine albumin standardized by urine creatinine. The standard screen for early kidney damage.
Medically reviewed by Youmna DiStefano, MD · Last reviewed September 2026
The short answer
Albumin/Creatinine Ratio is measured with a urine (random) sample; no fasting is needed. A typical reference range is 0.000 – 30.0 mg/g. At TestWell it's $24.99 all-in as Microalbumin (Urine Albumin/Creatinine Ratio), results in 1–3 business days, drawn at Quest. An out-of-range result is a prompt to look closer, not a diagnosis.

Albumin/Creatinine Ratio Reference Range
These are the typical adult reference ranges used by major US labs. Your report will include the specific range used by the lab that processed your sample.
| Population | Range |
|---|---|
| age 18+ | 0.000 – 30.0 mg/g |
Reference ranges are educational. Always interpret your result with the specific range printed on your lab report and discuss anything outside the range with a clinician.
What your Albumin/Creatinine Ratio result may mean
Above 30 mg/g indicates moderately increased albumin (microalbuminuria); above 300 mg/g is heavy albuminuria.
What a high Albumin/Creatinine Ratio means: causes, symptoms, next steps →Educational only — not a diagnosis. Many factors can influence a single result. Discuss anything that concerns you with a healthcare provider.
How do you get a Albumin/Creatinine Ratio test?
Order online, a licensed physician reviews the requisition, and you walk into a nearby lab for the draw. Albumin/Creatinine Ratio is available on its own or inside these panels — panels cost less per marker when you want the fuller picture.
| Option | Includes | Price |
|---|---|---|
| Microalbumin (Urine Albumin/Creatinine Ratio) | This marker only | $24.99 |
Quest vs. Labcorp for Albumin/Creatinine Ratio: which lab should you pick?

Frequently asked
Above 30 mg/g indicates moderately increased albumin (microalbuminuria); above 300 mg/g is heavy albuminuria. A single result above the reference range is a prompt to look closer with a clinician — often a repeat test and related markers — not a diagnosis on its own.
