Albumin and Creatinine with Albumin-Creatinine Ratio (ACR), Urine
One of the earliest signs of kidney damage, often years before kidney function declines.
Consider this test if:
- Living with diabetes or high blood pressure and screening for early kidney involvement
- Family history of kidney disease and you want a baseline
- Tracking whether blood pressure or glucose control is protecting your kidneys
- Confirming an abnormal dipstick urinalysis result
- Monitoring kidney impact of a medication or an existing CKD diagnosis
- HSA/FSA eligible
- Typical results in 1 day · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting required. An early-morning sample is preferred for the most reliable result. Avoid collecting during menstruation, an active urinary tract infection, or right after intense exercise, since blood, infection, and exertion can transiently raise albumin. A positive result is usually repeated on a second early-morning sample to confirm.

What this test is for
The urine albumin-to-creatinine ratio detects small amounts of albumin leaking into the urine, a sensitive early marker of damage to the kidney's filtering units. It is the standard screening test for chronic kidney disease and is especially important in diabetes and high blood pressure, where albumin in the urine commonly appears before glomerular filtration rate drops. An elevated ratio (30 mg/g or higher) that persists is used to diagnose and stage CKD, and it independently predicts cardiovascular events, so catching it early lets you tighten blood pressure and glucose control before damage progresses. A single high result is not enough: menstrual blood, urinary tract infection, hard exercise, and standing upright can all transiently raise albumin, so a positive should be confirmed on a repeat early-morning sample.
This spot-urine ratio is the right test for routine screening and tracking. A separate 24-hour or timed urine collection gives a more precise estimate when a result needs confirming, and the Kidney Panel pairs this ratio with serum creatinine and eGFR for a fuller assessment of kidney function.
Biomarkers tested
Includes 3 biomarkers
- Specimen
- Urine
- Measures
- Ratio
Urine creatinine tracks a waste product muscle breaks down at a steady rate, which makes it the reference point for judging whether a urine sample is concentrated or diluted. Labs use it to normalize other urine markers, most importantly albumin, into a ratio (ACR) that actually reflects kidney filtering rather than how much water you drank that morning. On its own it is rarely the number you care about, but pair it with albumin and it becomes one of the earliest ways to catch kidney strain from diabetes, high blood pressure, or high-protein training loads before symptoms show up.
- Specimen
- Urine
- Measures
- Mass concentration
Healthy kidneys hold onto albumin, filtering blood while keeping this protein out of urine. This test measures how much albumin leaks through, and even small amounts signal that the kidney's filtering barrier is starting to wear down, often years before creatinine or eGFR shift. It's a key early marker for diabetes and high blood pressure related kidney damage, so it's worth tracking as a baseline if you have either condition, a family history, or want to catch declining kidney function while it's still fully reversible.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost, covering the lab and what it takes to run the service. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
