24 Hours Urine Protein Test
Definition:
A 24-hour urine protein test measures the amount of protein excreted in the urine over a full 24-hour period. It helps evaluate kidney function.

Sample Type:

24-hour urine sample (collected over 24 hours)

Sometimes paired with a serum (blood) sample for comparison

Purpose:

To detect proteinuria (abnormal protein in urine)

To assess or monitor kidney diseases like glomerulonephritis, nephrotic syndrome, or diabetic nephropathy

To evaluate how well the kidneys filter waste and proteins

Normal Range:

Less than 150 mg/day is considered normal

Persistent proteinuria may indicate kidney damage

Procedure:

Urine is collected over 24 hours in a special container.

Proper storage (usually refrigeration) is important.

The total volume and protein content are measured in the lab.

Clinical Relevance:
High protein levels may indicate kidney damage, infections, or conditions like hypertension, diabetes, or lupus.
