Albumin Creatinine Ratio, Urine (Microalbumin)

Urine Albumin/Creatinine Ratio

This spot urine test detects small amounts of albumin leaking into the urine: an early warning sign of kidney damage. It is a key screening tool for diabetic kidney disease.

About This Test

What the Albumin Creatinine Ratio, Urine (Microalbumin) test tells you

This test looks for small quantities of albumin escaping into the urine: too little for a standard dipstick protein check to register, but enough to signal that the kidney's filters are under strain. The older name microalbuminuria refers to the size of the leak, not to a small kind of albumin; the protein is ordinary albumin, simply present in modest excess. Finding it is genuinely good news in one important sense: it identifies kidney damage at a stage when tightening control and adding the right medicines can slow it, and often reduce it.

What makes this version practical enough to repeat every year is that it needs only a single, untimed sample. Because a random sample can be dilute or concentrated depending on how much you have drunk, the albumin is expressed against the creatinine measured in the very same sample. Creatinine is produced and excreted at a fairly constant rate, so using it as the yardstick effectively cancels out hydration and yields a figure that can be compared fairly with last year's, without anyone having to collect urine across a whole day.

Its main role is annual screening in diabetes and in high blood pressure, where kidney damage is common, silent in its early stages, and modifiable if caught. One abnormal result, though, settles nothing. Albumin excretion rises transiently after vigorous exercise, during a fever or urinary infection, in heart failure and around menstruation, so an abnormal ratio is normally repeated on separate samples over the following months before it is taken to mean persistent kidney damage. Where precision matters more than convenience, a timed collection is used instead.

Why Get Tested?

Annual screening is recommended for all patients with type 1 or type 2 diabetes, and those with hypertension, to catch kidney damage at a reversible stage.

  • Annual diabetes screening

    It is the standard yearly kidney check in diabetes of either type, done at a stage where treatment still changes the outcome.

  • Kidney check in hypertension

    In people with raised blood pressure, albumin leak identifies who is already sustaining damage to the kidneys.

  • Wider vascular risk

    Albumin in the urine also flags strain on blood vessels generally, which your doctor factors into your overall risk picture.

  • Monitoring treatment effect

    Repeating the ratio shows whether the medicines and control measures already started are reducing the leak.

When This Test Is Ordered

Reasons your doctor may request the Albumin Creatinine Ratio, Urine (Microalbumin) test

Your doctor may order this test for any of the reasons below. Some are routine checks, others follow specific symptoms or an earlier result.

  • Annual diabetes & blood-pressure checks

    • You have diabetes, of either type, and are due your annual kidney check.
    • You have high blood pressure and your doctor is screening for kidney involvement.

  • Family history

    • You have a strong family history of kidney disease.

  • Following up a result or treatment

    • A medicine that protects the kidneys has been started and its effect needs following.
    • A routine dipstick suggested protein and the amount needs measuring properly.

Prep note
Physician reviewed

No fasting is needed.

A first-morning sample is preferred where possible, because it is less affected by the day's posture and activity. Clean the genital area first and collect a midstream sample to avoid contamination.

Avoid strenuous exercise the day before, and postpone the test if you have a urinary infection, a fever, or are menstruating, since all of these raise urinary albumin without any kidney problem. Drink as you normally would rather than deliberately loading up with water.

Tell your doctor about blood pressure medicines, anti-inflammatory painkillers and any recent scan involving contrast dye, and bring last year's result so the two can be compared.

Understanding Your Results

A result in the Normal band, reported in mg/g, is what this annual screen hopes for and needs neither treatment nor investigation. The Microalbuminuria band means a small excess of ordinary albumin is escaping into the urine: kidney damage caught early, while tightening control and the right medicines can still slow or reduce it. A result in the High band reflects a larger leak and is followed up more actively. Measuring albumin against creatinine from the same sample largely cancels out hydration, though urine that is unusually dilute or concentrated can still skew a random sample. A urinary infection or fever, strenuous exercise the day before, heart failure, and contamination with menstrual blood or discharge all lift the ratio without kidney disease. Your doctor confirms an abnormal result on separate samples and reads it with your symptoms, blood pressure and glucose control.

Ranges are a guide: your physician interprets your result alongside your symptoms and history.

Reading a High or Low Result

  • What a higher result can point to

    • Early diabetic kidney disease.
    • Kidney damage related to long-standing high blood pressure.
    • Glomerular disease affecting the filtering membranes.
    • A urinary tract infection, a fever, or heart failure, all of which raise albumin excretion temporarily.
    • Strenuous exercise in the day before the sample.
    • Contamination with menstrual blood or vaginal discharge.

These are possibilities, not diagnoses. A single value outside the reference range is interpreted alongside your symptoms, history and other tests: your doctor decides what it means for you.

Limitations & Safety

What this test cannot tell you

  • A positive result must be confirmed on repeat samples before it is taken to indicate kidney disease, because transient rises are common and often harmless.
  • A single random sample is less precise than a timed collection and can be skewed by urine that is unusually dilute or concentrated.
  • It detects albumin only, so proteins lost in some other kidney conditions are missed.
  • A low result is the normal finding and needs neither treatment nor investigation.

Risks of the blood draw

  • Mild bruising or brief soreness where the needle went in.
  • Occasional lightheadedness, which settles after a few minutes of rest.
  • Bleeding or infection at the site, which is rare with sterile single-use equipment.
Key Points
  • 1Microalbuminuria means a small excess of ordinary albumin, not a different protein.
  • 2Expressing albumin against creatinine from the same sample removes the effect of how dilute the urine is.
  • 3It is the earliest routinely available sign of kidney damage in diabetes and hypertension.
  • 4Any abnormal result should be confirmed on separate samples before conclusions are drawn.
  • 5Caught at this stage, the process can often be slowed or reversed with treatment.

A dipstick registers protein only once the leak is fairly substantial. This test measures albumin specifically and at much smaller quantities, so it detects damage at a stage where a dipstick is still negative.
