The normal ratio of BUN to creatinine in the blood is between 10 and 20 to 1, more or less, although this normal range varies with age and gender. Ratios higher than 20 to 1 or lower than 10 to 1 (with the above caveat) are both indicative of certain kidney problems.
(1)Department of Medicine and Geriatrics, Kochi Medical School. To estimate normal ranges of blood urea nitrogen (BUN) and serum creatinine (Cr) levels in the aged, we measured BUN and Cr levels in 332 cases of apparent-healthy elderly subjects (male, 152; female, 180) aged 70 years or more.e defined the normal range as range within the single SD-line of the remainder. The estimated normal range of BUN was 14-23 mg/dl both in male and female elderly subjects, and that of Cr was 0.9-1.3 mg/dl in male and was 0.7-1.1 mg/dl in female.
