LDH-isoenzymes in children. A comparison of values from capillary and venous blood

A comparison has been made of serum values of LDH-isoenzymes obtained by simultaneous sampling of capillary and venous blood in 40 normal children. No satisfactory correlation between the paired values could be found. Evaluation of the pattern of serum LDH-isoenzymes in children therefore requires a reference, i.e. normal values of isoenzymes obtained by the same technique of blood sampling.
