Understanding Creatinine
  • Creatinine is a waste product from muscle metabolism
  • Healthy kidneys filter creatinine from blood into urine
  • Higher blood creatinine may indicate kidney problems
  • Regular testing helps monitor kidney function
About GFR
  • GFR measures how well your kidneys filter blood
  • Normal GFR varies by age, gender, and body size
  • GFR typically decreases with age
  • Low GFR may indicate kidney disease
