Microalbumin-to-Creatinine Ratio, Urine — Qualitative Test Strip

Published: August 9, 2026Updated: August 17, 2026

A urine test strip that screens for albumin relative to creatinine, helping detect moderately increased albuminuria, an early sign of kidney damage.

What is this test?

This test checks urine for albumin, a protein that can leak through the kidneys, and compares it with urine creatinine. The result provides a screening estimate of the albumin-to-creatinine ratio.

Why might I need this test?

It may be used to screen people with diabetes, high blood pressure, or known kidney disease. Early albumin leakage can occur before other signs of kidney problems become apparent.

How is the test performed?

A urine sample is collected and placed on a reagent strip. The strip changes color according to the amount of albumin relative to creatinine, and the result is read and interpreted by a laboratory professional or clinician.

How do I prepare for the test?

Follow your clinician's collection instructions, which may include providing a first-morning or clean-catch urine sample. Tell the clinician about recent urinary infection, fever, intense exercise, or other temporary conditions that may affect the result.

Reference range

Adult: 3.5-5.0 g/dLN/A

Specimen: urine

No special preparation required. Avoid fatty meals before the test if possible.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

An increased urine albumin-to-creatinine ratio may indicate early kidney damage associated with diabetes, high blood pressure, or other kidney conditions. Exercise, fever, urinary infection, and changes in urine concentration can temporarily raise the result, so an abnormal screening result usually needs confirmation with a laboratory-based measurement.

Short name

Urine microalbumin/creatinine ratio

Frequently asked questions

Does this test diagnose kidney disease?
No. It is a screening test for albumin leakage. Clinical evaluation and confirmatory urine testing are needed if the result is abnormal.
Is this the same as a standard urine protein dipstick?
It is related but more focused: it estimates urine albumin relative to creatinine. A clinician may order additional tests to measure albumin or protein more precisely.
Can exercise or illness affect the result?
Yes. Strenuous exercise, fever, urinary infection, and dehydration can temporarily increase urinary albumin. Your clinician may recommend repeating the test when these conditions have resolved.
