Kidney Function

Kidney function tests measure how effectively your kidneys filter waste, balance fluids and maintain electrolytes. The most common markers include creatinine, BUN, eGFR and urine protein levels. According to Wikipedia’s renal function article, healthy kidneys also regulate blood pressure, acid–base balance and hormone production.

Doctors request these tests for many reasons: routine checkups, monitoring diabetes or high blood pressure, evaluating dehydration, or investigating swelling, fatigue or changes in urination. The numbers themselves can be confusing without context—that’s where the Kidney Function Analyzer helps by comparing your values with common adult reference ranges and summarizing what high or low results may mean in general terms.

The tool accepts serum creatinine, BUN, eGFR and optional urine ACR (albumin/creatinine ratio). After entering your values, clicking “Analyze Kidney Function” triggers a rules engine that compares each number with typical adult reference limits and labels them as Low, Normal or High.

The analyzer then looks for patterns. For example:

• High creatinine with low eGFR → reduced filtration efficiency.
• High BUN with normal creatinine → may reflect dehydration or diet effects.
• Elevated urine ACR → early signs of protein leakage through the kidneys.

Results appear in a clean layout with colored badges. Green indicates values within range, amber highlights mild abnormalities, and red draws attention to clearly abnormal results. These indicators are educational only and do not provide medical diagnosis.

Serum creatinine is a waste product filtered by the kidneys. Elevated levels often signal that filtration has slowed. Very low values are usually related to low muscle mass.

BUN (Blood Urea Nitrogen) reflects protein metabolism and hydration. When high, it may point to dehydration or reduced filtration. When low, it may indicate low protein intake or liver-related factors.

eGFR estimates how much blood your kidneys filter per minute. It is one of the main indicators used to classify chronic kidney disease stages in medical literature.

Urine ACR measures the amount of albumin leaking into urine. Even small increases (microalbuminuria) can be an early sign of kidney stress, especially in people with diabetes or hypertension.

For deeper insight into filtration markers, you may also explore the eGFR Calculator or assess electrolyte balance using the Electrolytes Analyzer.

Using the tool is simple and takes only a few moments:

• Open your kidney function test report from your laboratory or online portal.
• Locate creatinine, BUN, eGFR and urine ACR (optional).
• Enter the numbers into the corresponding fields on the analyzer.
• Click the “Analyze Kidney Function” button.
• Review the colored badges and educational summary.

You can adjust values and re-run the analysis to compare different reports. This helps visualize trends over time, but any concerns should always be discussed directly with your doctor.

For additional metabolic context, the CMP Analyzer may provide a broader overview of kidney-related electrolytes and proteins.

Kidney-related results are often interpreted alongside other blood tests. Helpful tools include:

• Creatinine Clearance Calculator – estimates filtration using urine output when available.
• Uric Acid Analyzer – useful when evaluating metabolic patterns.
• Electrolytes Analyzer – complements kidney assessment by showing sodium and potassium balance.
• BMI Calculator – often reviewed in metabolic and kidney health discussions.

These tools follow the same simple, educational approach and help you build a clearer picture of your overall metabolic status.

Is this analyzer a diagnostic tool?
No. It provides general educational explanations but does not diagnose kidney disease or determine treatment.

Can I use this tool to monitor treatment?
You may compare trends for educational purposes, but only a clinician can interpret kidney function for medical decisions.

Are reference ranges universal?
No. Ranges vary between laboratories. The analyzer uses common adult intervals to help you understand patterns.

Does the tool support children or pregnancy?
No. These groups have different normal ranges that must be interpreted by healthcare professionals.
