What Is a 24-Hour Urine Albumin Test?

The 24-Hour Urine Albumin test evaluates how much albumin passes from your blood into your urine in 24 hours. Albumin is an essential blood protein, and healthy kidneys usually prevent it from leaking into urine.

If albumin appears in higher amounts, it may indicate early kidney damage—often before symptoms appear.

Why Is the 24-Hour Urine Albumin Test Important?

This test is especially important because it:

1. Detects early kidney disease

2. Monitors diabetic nephropathy

3. Assesses hypertension-related kidney damage

4. Helps evaluate cardiovascular risk

5. Tracks kidney function progression over time

Early detection through a 24-Hour Urine Albumin test can prevent irreversible kidney failure with timely treatment.

Who Should Get This Test?

Doctors commonly recommend this test for:

1. People with diabetes

2. Patients with high blood pressure

3. Individuals with a family history of kidney disease

4. Those experiencing swelling in legs or face

5. Patients with abnormal routine urine test results

How Is the 24-Hour Urine Albumin Test Done?

The procedure is simple but requires accuracy:

1. Discard the first urine sample in the morning.

2. Collect all urine for the next 24 hours in a provided container.

3. Store the container in a cool place.

4. Submit the sample to the laboratory after 24 hours.

Normal Range of 24-Hour Urine Albumin

Causes of High Urine Albumin Levels

Elevated albumin levels may occur due to:

1. Poorly controlled diabetes

2. Long-term hypertension

3. Kidney infections

4. Glomerulonephritis

5. Excessive physical exertion

6. Dehydration

Temporary increases can also occur due to fever or stress.
