Learn which blood levels indicate kidney damage, focusing on elevated BUN and creatinine and their normal ranges for men and women.

80 views

Elevated levels of blood urea nitrogen (BUN) and creatinine often indicate kidney damage. Normal BUN levels are between 7-20 mg/dL and normal creatinine levels are 0.6-1.2 mg/dL for men and 0.5-1.1 mg/dL for women. High levels can suggest impaired kidney function and should be assessed by a healthcare professional.

  2. How do elevated BUN and creatinine levels indicate kidney damage? High levels of BUN and creatinine suggest impaired kidney function as these substances are normally filtered out by healthy kidneys.
  3. When should I see a healthcare professional about kidney function? If your blood tests show elevated BUN and creatinine levels, or if you experience symptoms related to kidney issues, consult a healthcare professional promptly.
