Hi, I am 51 years old and I done my physical check up, the blood test result listed my creatinine 0.80. The doc comments saying for my age the reference limit for creatinine is approximately 13% higher for people identified as African-American. I m Asian and I go to gym 5 days a week. Is that possible made my creatinine higher than my age? Thanks,
Welcome to Chat Doctor, Normal levels of creatinine in the blood for a male of your age is 0.6 to 1.2 mg/DL. Creatinine levels depend on muscle mass and are slightly higher in males compared to females. Abnormal high values are usually seen kidney diseases and muscle diseases. Your creatinine level is normal for your age, gender and ethnicity. You have nothing to worry about. Hope that answers your question.  Chat Doctor.
