Kidney Function Creatinine Clearance (CrCl) Calculator

Calculate kidney function creatinine clearance from creatinine level, age, gender, and weight.

Kidney Function Creatinine Clearance (CrCl) Calculator

Calculate kidney function creatinine clearance from creatinine level, age, gender, and weight.

Input your kidney function data

Formula

Creatinine clearance (Cockcroft-Gault) = ((140 - age) × weight × gender factor) / (72 × creatinine).

Gender factor: 1.0 for males, 0.85 for females.

Normal ranges: Men: 90-130 mL/min, Women: 80-120 mL/min. Values below 60 mL/min indicate reduced kidney function. Values below 15 mL/min indicate severe kidney failure.

Creatinine clearance estimates glomerular filtration rate (GFR) and kidney function. It decreases with age and is affected by kidney disease, medications, and other factors.

Steps

  • Enter creatinine level (mg/dL) from blood test.
  • Enter your age (creatinine clearance decreases with age).
  • Select gender (clearance formulas differ for males and females).
  • Enter weight (kg) for clearance calculation.
  • Review creatinine clearance, kidney function status, and recommendations.

Complete guide snapshot

Creatinine clearance (CrCl) estimates how well the kidneys filter creatinine from the blood, providing a measure of kidney function. Normal CrCl ranges from 90-130 mL/min for men and 80-120 mL/min for women.

Use this calculator to assess creatinine clearance from creatinine level, age, gender, and weight using the Cockcroft-Gault equation.

FAQs

What is creatinine clearance?

Creatinine clearance (CrCl) estimates how well the kidneys filter creatinine from the blood. It is a measure of kidney function and glomerular filtration rate (GFR).

What are normal creatinine clearance values?

Normal CrCl ranges from 90-130 mL/min for men and 80-120 mL/min for women. Values below 60 mL/min may indicate kidney dysfunction. Values below 15 mL/min indicate severe kidney failure.

What is creatinine?

Creatinine is a waste product from muscle metabolism that is filtered by the kidneys. Elevated blood creatinine levels may indicate reduced kidney function.

What causes low creatinine clearance?

Low CrCl can result from chronic kidney disease, acute kidney injury, dehydration, medications, diabetes, hypertension, or other conditions affecting kidney function.

How is creatinine clearance calculated?

CrCl is calculated using the Cockcroft-Gault equation: CrCl = ((140 - age) × weight × gender factor) / (72 × creatinine). Gender factor: 1.0 for men, 0.85 for women.

Does age affect creatinine clearance?

Yes. Creatinine clearance naturally decreases with age. Normal CrCl decreases by approximately 1 mL/min per year after age 40. Age is a key factor in the calculation.

What about gender differences?

Men typically have higher muscle mass and creatinine production, resulting in higher normal CrCl ranges. Women have lower normal ranges due to lower average muscle mass.

Can I track creatinine clearance at home?

Home CrCl tests are limited. Blood creatinine and calculated CrCl through healthcare providers provide accurate kidney function assessment. Regular monitoring is important for kidney health.

What about kidney disease stages?

Kidney disease is staged by eGFR/CrCl: Stage 1 (≥90), Stage 2 (60-89), Stage 3 (30-59), Stage 4 (15-29), Stage 5 (<15). Lower stages indicate more severe disease.

When should I consult a healthcare provider?

Consult a healthcare provider if CrCl is below 60 mL/min, if creatinine is elevated, if you have symptoms (swelling, fatigue, changes in urination), or if you have risk factors for kidney disease.

Summary

This tool calculates kidney function creatinine clearance from creatinine level, age, gender, and weight.

Outputs include creatinine level, creatinine clearance, clearance percentage, clearance score, status, recommendations, an action plan, and supporting metrics.
