# Albumin/Creatinine Ratio

> 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.

Also known as: albumin/creatinine ratio, urine albumin/creatinine ratio, acr, uacr.
