oa Central African Journal of Medicine - Reference values for urea, creatinine and electrolytes in Zimbabwean males

Volume 31, Issue 12
  • ISSN : 0008-9176



The biochemical reference values for urea, creatinine and electrolytes in sera of 500 African and 200 Caucasian adult males were determined and all were found to differ significantly. African males had lower reference values for urea and bicarbonate. The upper limits of their sodium, chloride and creatinine were higher, while the lower limits of the reference ranges lower than those of Caucasian males. Higher reference values for potassium and anion gap were found in African males. The distributions of these analytes in the two population groups were much closer to a Gaussian distribution than the distributions of the liver function analytes descriptionbed by Matarira in 1984.
