Albumin / Creatinine Ratio, 24 Hrs Urine
This test measures the ratio of albumin to creatinine in a 24-hour urine collection. It is used to detect early kidney damage, particularly in diabetes and hypertension patients.

What the Albumin / Creatinine Ratio, 24 Hrs Urine test tells you
Healthy kidneys hold albumin back. It is the most abundant protein in blood, and the filtering units are built to let waste through while keeping proteins of that size in circulation. When those filters are damaged, albumin begins to escape into the urine, and it does so long before any change shows up in blood tests of kidney function. Measuring urinary albumin is therefore one of the earliest practical windows onto kidney injury — and, importantly, it opens at a stage when treatment can still slow or reverse the process.
The complication is that urine concentration swings through the day with how much you drink, so the raw amount of albumin in a sample is a poor guide on its own. Creatinine is excreted at a fairly steady rate, so expressing albumin against creatinine cancels out the dilution effect and produces a figure that stands comparison between samples and between people. This version of the test applies that calculation to a full twenty-four hour collection, which additionally averages out shorter fluctuations caused by posture, activity and time of day.
The timed collection is more demanding than handing in a single sample, which is why routine screening usually uses a spot ratio instead. This version earns its place when precision matters most: confirming an abnormal spot result, quantifying protein loss for a kidney clinic, following someone whose treatment is being adjusted, or assessing protein in pregnancy. Whichever method is used, one abnormal result is rarely acted on alone. Albumin leak rises transiently after vigorous exercise, during a fever or urinary infection, in heart failure and around menstruation, so the test is normally repeated before anything is concluded — persistence, not a single value, is what points to something structural.
Recommended for patients with diabetes, hypertension, or a family history of kidney disease to screen for early kidney damage and guide preventive treatment.
Albumin appears in urine well before blood measures of kidney function change, giving the earliest practical warning in diabetes and high blood pressure.
A timed collection removes much of the hour-to-hour variation that can make a single random sample misleading.
The result influences whether medicines that reduce protein leak and protect the kidney are started or increased.
Repeated measurements show whether albumin loss is stable, improving on treatment, or progressing.
Reasons your doctor may request the Albumin / Creatinine Ratio, 24 Hrs Urine 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.
Diabetes & blood pressure
You have diabetes and an earlier random urine result needs confirming properly.
You have high blood pressure and your doctor is checking for kidney involvement.
A family history of kidney disease means your doctor wants a careful baseline.
Precise quantification
You attend a kidney clinic and precise quantification of protein loss is needed.
You are pregnant and protein in the urine needs quantifying accurately.
Treatment response
Treatment to reduce protein leak has been started and its effect is being measured.

The albumin-to-creatinine ratio screens for early kidney damage.
Ranges are a guide — your physician interprets your result alongside your symptoms and history.
What a higher result can point to
- Diabetic kidney disease, in which albumin leak is often the first detectable sign.
- Kidney damage from long-standing high blood pressure.
- Glomerular disease, where the filtering membranes themselves are inflamed or scarred.
- A urinary tract infection, a fever, or blood contaminating the sample.
- Vigorous exercise shortly before or during the collection, and heart failure, both of which raise albumin excretion temporarily.
- Pre-eclampsia and other pregnancy-related kidney stress.
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.
What this test cannot tell you
- A single raised result does not establish kidney disease; the finding must persist across separate samples taken on different days, because transient rises are common.
- An incomplete or badly timed collection is the commonest source of error and can shift the result in either direction.
- Infection, fever, menstrual blood and recent strenuous exercise raise albumin excretion without any kidney disease being present.
- The test measures albumin specifically and will miss other urinary proteins, which need a different test.
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.
- 1Albumin in urine is one of the earliest signs of kidney damage, appearing before blood tests change.
- 2Expressing albumin against creatinine corrects for how dilute or concentrated the urine happens to be.
- 3A low ratio is the normal, healthy finding and needs no action.
- 4Collection technique matters as much as the laboratory work — missing urine invalidates the result.
- 5Because a rise can be transient, an abnormal result is repeated before your doctor acts on it.

Talk to our team→Because urine can be dilute or concentrated depending on what you have drunk, and that alone can move the albumin figure substantially. Creatinine is excreted at a steady rate, so using it as the yardstick removes that distortion and makes samples genuinely comparable.
Tell the laboratory rather than guessing. A missed passing makes the total falsely low, and it is better to repeat the collection than to act on a result that understates the protein loss.
It often is at this early stage. Better glucose and blood pressure control, along with medicines that reduce pressure inside the filtering units, frequently reduce albumin excretion — which is a large part of why the test is done early rather than late.
Hard physical effort transiently increases the amount of albumin the kidney lets through, even in people with entirely healthy kidneys. It settles within about a day, so avoiding heavy exertion during the collection prevents a false alarm.
