The Frequency Distributions Of Commonly Determined Blood Constituents In Healthy Blood Donors.

Abstract The frequency distributions of 19 biochemical variables in blood have been studied on 1000 blood donors. The distributions within age/sex groups of calcium, CO2 capacity, chloride, ions difference, inorganic phosphate, potassium, sodium and total protein values did not differ significantly from Gaussian form; those of alkaline phosphatase, cholesterol, creatinine, glucose, glutamic oxaloacetic transaminase, iron, protein-bound iodine, urea and urate could be converted to close agreement with Gaussian distributions by logarithmic transformations, although the glucose distribution remained significantly long-tailed. Albumin and globulin were slightly skew in opposite directions. There was no evidence that distributional shape was affected by age or sex.
