What Are Bad Kidney Function Numbers? Understanding GFR, Creatinine & Proteinuria

Learn what bad kidney function numbers mean, including low GFR, high creatinine, and proteinuria, and how they indicate chronic kidney disease.

180 views

Bad kidney function numbers are typically indicated by a GFR (Glomerular Filtration Rate) less than 60 mL/min/1.73 m^2 for 3 months or more, suggesting chronic kidney disease (CKD). Additionally, elevated serum creatinine levels—above 1.2 for women and 1.4 mg/dL for men—signal poor kidney function. High levels of proteinuria (protein in urine) also point to kidney damage. Early detection and treatment are key to managing kidney health, so regular monitoring is advisable for those at risk.

FAQs & Answers

  1. What GFR level indicates bad kidney function? A GFR less than 60 mL/min/1.73 m² for 3 months or more indicates reduced kidney function and may suggest chronic kidney disease.
  2. What creatinine levels are considered high for kidney function? Serum creatinine levels above 1.2 mg/dL for women and 1.4 mg/dL for men are generally considered elevated, indicating possible poor kidney function.
  3. What does proteinuria mean for kidney health? Proteinuria, or high levels of protein in urine, often signals kidney damage and is a key indicator used to assess kidney function.
