# Urine Creatinine

> Urine Creatinine is measured with a urine (random) sample; no fasting is needed. A typical reference range is 20.0 – 320 mg/dL. 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: urine creatinine, creatinine, urine.
