September 20, 2024

Excess protein in urine is a common clinical finding observed in 8-33% of the general population. However, despite its prevalence, protein in urine isn't a normal finding. The kidneys are organs responsible for filtering waste from blood and making urine. When this delicate filtering process is compromised, protein can leak into the urine, indicating potential kidney damage.Β 

Measuring protein levels in urine is a simple, cost-effective, and non-invasive screening test that provides valuable insights into kidney health. However, not all proteinuria is pathologic; it is the responsibility of the healthcare provider to distinguish between transient, benign causes and those indicative of underlying health problems, ensuring appropriate diagnosis and management.

Understanding High Protein in Urine

Proteinuria is a medical condition characterized by an abnormal amount of protein in the urine. Normally, urine contains only trace amounts of protein, as the kidneys efficiently filter blood to retain essential proteins while excreting waste products. When this filtering mechanism is compromised, larger quantities of protein, particularly albumin, can leak into the urine, leading to proteinuria.

Proteinuria is a significant clinical finding because it often indicates underlying kidney damage or disease. Under normal circumstances, the kidneys selectively retain essential proteins, electrolytes, and water while eliminating the body's waste products via urine. Their glomeruli (the kidneys' filtering units) act as a barrier that prevents large molecules, such as albumin, from passing into the urine. When this barrier is compromised, it signifies that the kidneys are not functioning properly, which can lead to progressive kidney damage and, if left untreated, chronic kidney disease (CKD). (29)Β 

Reference RangesΒ 

In healthy individuals, the amount of protein in the urine is minimal, typically less than 150 mg per day. A more specific marker, albumin, is usually less than 30 mg per day. Proteinuria is classified as abnormal when protein levels exceed these thresholds. (23)Β 

‍Microalbuminuria, an early sign of kidney damage, occurs when albumin excretion is between 30 and 300 mg per day.Β 

Macroalbuminuria, or overt proteinuria, is diagnosed when protein levels exceed 300 mg per day.

Types of ProteinuriaΒ 

Most cases of proteinuria can be understood in terms of one or more of the following categories:

Glomerular Proteinuria: This is the most common type and occurs when the glomeruli are damaged, allowing large amounts of protein to pass into the urine. Proteinuria greater than 2 grams per day is usually the result of glomerular disease. (6, 39)Β 

‍Tubular Proteinuria: This type occurs when the renal tubules, which are responsible for reabsorbing proteins after filtration, are damaged. This leads to the leakage of smaller proteins that would typically be reabsorbed. Tubular proteinuria is commonly seen in conditions like acute interstitial nephritis caused by nonsteroidal anti-inflammatory drugs (NSAIDs) and normally results in proteinuria of less than 2 grams per day. (6, 39)

Overflow Proteinuria: In this type, excessive production of low-molecular-weight proteins overwhelms the kidneys' ability to reabsorb them, leading to their presence in the urine. This can occur in conditions such as multiple myeloma, where there is an overproduction of immunoglobulin light chains (Bence Jones proteins). (6, 39)

Causes of High Protein in Urine

Proteinuria can be caused by various factors, ranging from temporary conditions to serious underlying health problems.Β 

Transient Causes

Transient or benign proteinuria refers to temporary increases in protein levels in the urine that are not associated with long-term kidney damage. These causes are often reversible and may not require extensive treatment. Common benign causes include:

Exercise-Induced Proteinuria: Strenuous physical activity can temporarily increase protein excretion in the urine. This type of proteinuria usually resolves within 24 hours after the cessation of exercise.

Orthostatic Proteinuria: This condition occurs in some individuals, particularly young adults, when they are upright for prolonged periods. Protein excretion increases when standing and normalizes when lying down. It is generally harmless and does not indicate kidney disease. (24)Β 

Fever or Acute Illness: High body temperature or acute illnesses, such as infections, can temporarily increase protein levels in the urine. This is usually a response to the body's inflammatory process and subsides once the underlying condition is resolved. (22)Β 

Dehydration: Severe dehydration can lead to a transient increase in urine protein concentration, as reduced fluid intake or excessive fluid loss concentrates urine. Proper hydration typically resolves this issue.

Pathological Causes

Pathological proteinuria is indicative of underlying kidney damage or systemic disease. This type of proteinuria is persistent and often requires medical intervention. Common pathological causes include:

Diabetic Nephropathy: In diabetes, prolonged high blood glucose levels can damage the glomeruli, leading to glomerular proteinuria. Diabetic nephropathy is a leading cause of chronic CKD and requires careful management. (41)Β 

‍Hypertensive Nephropathy: Chronic high blood pressure can damage the small blood vessels in the kidneys, leading to protein leakage into the urine. This condition is also a significant risk factor for CKD. (46)Β 

Glomerulonephritis: This group of diseases involves inflammation of the glomeruli, leading to increased permeability and proteinuria. Glomerulonephritis can result from infections, autoimmune diseases, or exposure to toxic substances. (21)Β 

Kidney Infections: Severe infections, such as pyelonephritis, can cause inflammation and damage to the kidney tissues, resulting in protein leakage.

‍Multiple Myeloma: This type of cancer causes the overproduction of abnormal proteins (light chains) by plasma cells. These proteins can overwhelm the kidneys' filtering capacity, leading to overflow proteinuria. (20)Β 

Protein Levels in Urine During Pregnancy

During pregnancy, a slightly higher threshold for proteinuria is used, with normal levels considered up to 300 mg per day. When protein levels exceed 300 mg per day, it is considered abnormal and may require further investigation, especially in the context of other symptoms like high blood pressure.

The most concerning cause of elevated protein levels in pregnancy is preeclampsia, a condition characterized by high blood pressure, proteinuria, and often edema (swelling). Preeclampsia typically occurs after 20 weeks of gestation and can have serious complications for both the mother and the baby if left untreated. It is one of the leading causes of maternal and fetal morbidity and mortality.

Pregnant women are more prone to urinary tract infections (UTIs), which can cause proteinuria. A UTI can increase protein levels in the urine but should resolve with antibiotic treatment.

Pregnant women with pre-existing kidney disease may exhibit elevated protein levels in urine. CKD can worsen during pregnancy, necessitating close monitoring. (42)Β 

Routine urine tests are standard practice in prenatal care to detect proteinuria early. If elevated protein levels are detected, additional tests may be ordered to assess kidney function and other potential complications. Managing proteinuria during pregnancy involves addressing the underlying cause. For example, in cases of preeclampsia, management may include antihypertensive medications, close monitoring of fetal growth, and possibly early delivery if the condition threatens the health of the mother or baby. (19, 32)Β 

Lab Tests for Diagnosing High Protein in Urine

Measuring the concentration of protein in urine is integral to diagnosing proteinuria.Β 

Step 1: Urinalysis

A urinalysis is an easy test that can be conducted on an outpatient basis and requires the patient to collect a small urine sample.Β 

A urine dipstick test is a simple, quick test used to check for the presence of certain substances in the urine, such as proteins, glucose, ketones, blood, and more. It involves dipping a thin, plastic strip coated with chemicals (the dipstick) into a urine sample. The chemicals on the strip react with the substances in the urine, causing color changes on different sections of the strip. These color changes can then be compared to a chart to determine if there are abnormal levels of substances, like protein, in the urine.

The urine dipstick primarily detects albumin in urine, and the results are graded as (6):

  • Negative (less than 10 mg/dL)
  • TraceΒ  (10-20 mg/dL)
  • 1+ (30 mg/dL)
  • 2+ (100 mg/dL)
  • 3+ (300 mg/dL)
  • 4+ (1,000 mg/dL)

False-negative results can occur when urine is dilute. False positive results can occur when patients have recently been exposed to iodinated contrast agents, the urine is alkaline, or blood is in the urine. (6, 39)

A urine sample should be inspected microscopically when proteinuria is detected with a dipstick. Microscopic analysis can provide clues to the underlying cause of abnormal laboratory findings, such as UTI or kidney disease. (6)Β 

Step 2: Quantify Proteinuria

When a diagnosis of persistent proteinuria has been established (proteinuria present on at least three separate occasions), a 24-hour urine collection or a urinary protein-to-creatinine ratio (UPr/Cr) on a random urine specimen should be obtained to quantify proteinuria. (6)Β 

A 24-hour urine protein collection is performed by having the patient discard the first morning void and then collecting all subsequent urine until the first void of the next day.Β 

The UPr/Cr is a more accurate alternative to the 24-hour urine collection. It is measured with a random urine sample. The ratio is equivalent to the number of grams of protein excreted daily in urine. For example, a ratio of less than 0.2 is equivalent to less than 0.2 grams of protein daily (a normal finding).Β 

Additional Testing and Biomarkers

Once proteinuria has been established and quantified, your doctor will want to order additional tests to better understand the underlying cause for high protein levels. These often include:Β 

Kidney Function Tests (12):Β Β 

  • Blood urea nitrogen (BUN) is a blood test that measures the amount of urea nitrogen in the blood. Urea is a waste product formed in the liver when the body breaks down proteins. It is normally filtered out of the blood by the kidneys and excreted in urine. If the kidneys are not functioning properly, they may not remove urea efficiently, leading to elevated BUN levels.Β 
  • Creatinine is a waste product generated from the normal breakdown of muscle tissue. The kidneys filter it out of the blood and excrete it in the urine. Elevated levels of creatinine in the blood can indicate that the kidneys are not functioning correctly, as they cannot efficiently filter out this waste product.
  • The BUN/creatinine ratio compares the levels of BUN and creatinine to help doctors determine the cause of kidney dysfunction.
  • Glomerular filtration rate (GFR) is the rate at which blood is filtered through the kidneys. It is a marker used to diagnose and stage kidney disease. The lower the GFR value, the more advanced the disease. GFR can be estimated with equations that consider the patient's size, age, biological sex, race, and creatinine levels.Β 
  • Creatinine clearance measures the rate at which the kidneys filter creatinine from the blood and is the best measure of actual GFR. Reductions in creatinine clearance are associated with kidney disease.

Imaging Studies: CT scans and ultrasounds can visualize problems in the urinary tract causing abnormal lab results. Kidney stones, tumors, or other urinary tract obstructions can cause proteinuria. (33)Β 

Treatment and Management of High Protein in Urine

Patients may require regular follow-up care by their primary care physician or nephrologist. Generally, patients will be routinely monitored for the severity of proteinuria, kidney disease, treatment success, and complications.Β 

Recommendations for treating proteinuria will depend on the cause.Β 

For example, patients with diabetes or high blood pressure should work with their doctor to manage their blood sugar and blood pressure levels through diet, exercise, supplements, and medications.Β 

Patients with kidney disease will be managed with medication and dietary modifications, such as sodium and mild protein restriction. Patients with advanced kidney disease will require dialysis and a kidney transplant.Β 

Regardless of the cause of proteinuria, your doctor may prescribe you an angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) medication. These medications can reduce pressure inside the kidneys, helping to preserve kidney function and reduce proteinuria. (39)Β 

Transient proteinuria may not require treatment. Instead, your doctor may recommend you follow general guidelines for preserving kidney health, such as:Β 

  • Eat a diet rich in fruits and vegetables, such as the DASH diet
  • Limit sodium intake
  • Eat more fiber
  • Drink water to avoid getting dehydrated
  • Exercise regularly, aiming for at least 150 minutes of aerobic activity every week
  • Quit smoking
  • Avoid taking NSAIDs

Patient Education and Support

If you ever find yourself confused about your lab results, don't hesitate to ask your doctor for clarification. Your doctor can explain and help interpret what the results mean for you. It's important to stay informed and proactive about your health, especially when it comes to conditions like kidney disease.

Keep a close eye on any symptoms that may indicate kidney issues. These can include:

  • Swelling in your legs or ankles
  • Frequent urinationΒ 
  • Blood in the urine
  • Frothy urine
  • Persistent fatigue
  • Changes in appetite
  • Itchy skin
  • Muscle cramps

If you notice any new or worsening symptoms, consult your doctor promptly. Early intervention can make a significant difference in managing kidney health and preventing further complications.
