Why Kidney Testing Matters
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.
