Purpose Evaluate Kidney Function: Helps determine if the kidneys are functioning properly by filtering and retaining proteins. Diagnose Kidney Disorders: Identifies conditions such as glomerulonephritis, nephrotic syndrome, or diabetic nephropathy. Monitor Chronic Conditions: Used in monitoring diseases like diabetes or hypertension that can affect kidney health. Procedure Collection: All urine passed in a 24-hour period is collected in a special container provided by the healthcare provider. Storage: The container should be kept cool, usually refrigerated, during the collection period. Completion: After 24 hours, the collected urine is returned to the laboratory for analysis. Normal Values Adults: Generally, less than 150 mg of protein in 24 hours is considered normal. Values may vary: Depending on the laboratory and the patient's health conditions. Interpretation Normal: Indicates proper kidney function with no significant protein loss. Elevated Protein Levels: May suggest kidney damage, glomerular disease, infections, or other systemic conditions affecting the kidneys. Clinical Significance Low Protein: Generally not a concern but should be discussed with a healthcare provider. High Protein: Requires further investigation to determine the underlying cause and appropriate treatment. Factors Affecting Results Hydration Status: Dehydration or overhydration can affect protein concentration. Diet: High protein intake can temporarily increase urinary protein levels. Physical Activity: Intense exercise before the test can elevate protein levels. Follow-Up Additional Testing: If high levels of protein are detected, further tests such as blood tests, imaging, or a kidney biopsy may be recommended. Treatment: Based on the underlying cause, treatment may include medications, dietary changes, or managing underlying conditions like diabetes or hypertension.
The 24-hour urinary total protein test measures the amount of protein excreted in the urine over a 24-hour period. This test helps diagnose and monitor kidney function and various conditions that can cause proteinuria (the presence of excess protein in urine). Purpose: To evaluate kidney function. To detect and monitor kidney diseases such as nephrotic syndrome. To identify conditions like diabetes or hypertension that may affect the kidneys. Procedure: Preparation: You may be instructed to avoid certain medications and foods before the test. Collection: Collect all urine produced in a 24-hour period. This typically starts in the morning. Discard the first urine sample, and then collect all subsequent urine in a provided container. Storage: Keep the collected urine in a cool place, usually refrigerated. Completion: Return the container to the lab or healthcare provider after 24 hours. Normal Range: Less than 150 milligrams per 24 hours is considered normal. High Protein Levels Indicate: Kidney disease or damage Infections Diabetes High blood pressure

How our test process works!
The 24-hour urinary total protein test measures the amount of protein excreted in urine over a 24-hour period. It helps assess kidney function and detect conditions that cause abnormal protein leakage in the urine.
Why it’s done:
- Kidney diseases: Detect conditions like nephrotic syndrome, glomerulonephritis, or diabetic nephropathy.
- Systemic conditions: Identify systemic diseases such as diabetes, hypertension, or autoimmune disorders that may affect kidneys.
- Monitoring: Evaluate the effectiveness of treatment for kidney-related conditions.
Who may need it:
- Individuals with symptoms of kidney disease (e.g., swelling, foamy urine).
- Those with risk factors like diabetes, hypertension, or family history of kidney disorders.
Normal Range
- Normal protein excretion: <150 mg/24 hours.
- Values above this suggest proteinuria, which may indicate kidney or systemic disease.
Interpretation
- Normal results: Less than 150 mg/24 hours.
- Mild proteinuria: 150–500 mg/24 hours (often associated with early kidney disease or transient causes like exercise or fever).
- Moderate to severe proteinuria: >500 mg/24 hours (suggestive of significant kidney damage or systemic illness).
- Nephrotic range: >3,500 mg/24 hours (characteristic of nephrotic syndrome).
Other considerations:
- Transient proteinuria can occur due to exercise, fever, or dehydration.
- Persistent proteinuria usually requires further investigation to identify underlying causes.
Sample Type
- Collection: Urine is collected over a full 24-hour period. The total volume is measured, and a small portion is sent for analysis.
- Instructions:
- Discard the first urine sample of the day.
- Collect all urine voided thereafter in a clean container, including the first sample of the next day.
- Keep the urine refrigerated during collection to preserve its integrity.
