At Test Smartly Labs, we offer comprehensive kidney function testing to help detect issues early, prevent complications, and ensure your kidneys perform at their best.

Signs You Might Need a Kidney Test

Because kidney disease can be symptom-free in its early stages, routine screening is essential—especially for individuals with high blood pressure, diabetes, or a family history of kidney disease.

Common Symptoms of Kidney Problems

• Swelling in the legs, ankles, or face
• Fatigue or unexplained weakness
• Changes in urination, including frequency, foamy urine, or dark-colored urine
• Blood in the urine
• Difficulty concentrating or brain fog
• Persistent nausea or loss of appetite
• Muscle cramps or restless legs
• High blood pressure that is difficult to control

If you experience any of these symptoms, a kidney function test can help identify potential issues before they become more serious.

Comprehensive Kidney Tests Available at Test Smartly Labs

We offer a wide range of kidney function tests to evaluate how well your kidneys are filtering waste and maintaining balance in the body.

1. Kidney (Renal) Panel Basic

• Measures key kidney function markers, including blood urea nitrogen (BUN), creatinine, and electrolytes.
• Provides a general assessment of kidney function and detects early signs of kidney disease.

Best for: Routine kidney health screening and monitoring kidney function over time.

2. Kidney (Renal) Panel Ultimate

• Includes everything in the Basic Panel plus additional protein levels and filtration efficiency tests.
• Offers a more detailed analysis of kidney performance.

Best for: Individuals at higher risk of kidney disease, including those with diabetes or high blood pressure.

3. Kidney (Renal) Profile Comprehensive

• Includes BUN, creatinine, eGFR (glomerular filtration rate), uric acid, total protein, and urine protein levels.
• Provides a full-spectrum evaluation of kidney health and waste filtration.

Best for: Individuals experiencing symptoms of kidney dysfunction or those needing a detailed kidney health assessment.

4. BUN (Blood Urea Nitrogen) Test

• Measures the amount of nitrogen in the blood that comes from waste produced by protein metabolism.
• High BUN levels may indicate kidney disease, dehydration, or high protein intake.

Best for: Checking how efficiently the kidneys are filtering waste.

5. Creatinine, Serum

• A waste product from muscle metabolism filtered by the kidneys.
• Elevated creatinine levels may indicate reduced kidney function.

Best for: Monitoring kidney disease and evaluating overall kidney performance.

6. eGFR (Glomerular Filtration Rate)

• Estimates how well the kidneys filter blood by calculating creatinine levels in relation to age, sex, and race.
• A lower eGFR indicates declining kidney function and potential kidney disease.

Best for: Early detection of kidney disease and assessing filtration efficiency.

7. Cystatin C Blood Test

• Measures a protein that reflects kidney function independently of muscle mass.
• More sensitive than creatinine for detecting early kidney disease, especially in older adults.

Best for: Early-stage kidney disease detection and monitoring kidney function over time.

8. Uric Acid, Serum

• Measures uric acid levels, a waste product from the breakdown of purines found in food.
• High levels may indicate kidney dysfunction, gout, or metabolic disorders.

Best for: Individuals with a history of kidney stones, gout, or metabolic syndrome.

9. Protein and Creatinine (Urine Test)

• Measures protein and creatinine levels in the urine.
• High protein levels in urine may indicate kidney disease or damage.

Best for: Evaluating protein leakage from the kidneys, an early sign of kidney dysfunction.

10. Urinalysis, Complete with Microscopic Examination

• Detects protein, blood, glucose, and bacteria in urine.
• Helps diagnose kidney infections, kidney stones, and early kidney disease.

Best for: A general kidney and urinary tract health check.

11. Protein, Total, Serum

• Measures the total amount of protein in the blood, including albumin and globulin.
• Low protein levels may indicate kidney or liver disease, while high levels could signal inflammation or dehydration.

Best for: Monitoring kidney and liver health.

Who Should Get Kidney Testing?

Regular kidney testing is recommended for individuals who:

• Have diabetes or high blood pressure, as these are major risk factors for kidney disease
• Have a family history of kidney disease
• Experience frequent kidney stones or urinary tract infections
• Have swelling in the legs, ankles, or face
• Are over 60 years old, as kidney function naturally declines with age
• Have heart disease or other chronic conditions
• Experience unexplained fatigue, nausea, or changes in urination

Early detection of kidney disease allows for better treatment options and lifestyle changes to prevent further damage.
