Differences in concentration of galactose in arterial, capillary, and venous blood following a single intravenous injection.

Abstract

Galactose concentration was studied in simultaneously removed samples of arterial, venous, and capillary blood following a single intravenous injection. The venous concentrations were for a period higher than the arterial ones. The capillary concentrations were not different. Galactose elimination capacity for arterial blood did not differ significantly from that for venous or capillary blood, while galactose half-time for arterial blood differed from that for venous blood but not from that for capillary blood. It is concluded that for theoretical studies arterial blood is to be preferred.
