title: [Folic acid substitution in hemodialyzed patients. Folic acid levels in plasma and erythrocytes].
abstract: Investigations of folic acid levels in plasma and erythrocytes. In 20 patients on hemodialysis with and without folic acid substitution the concentration of folic acid in plasma and in red cells was estimated by radioassay. In patients, who were substituted with folic acid concomitantly with elevated folic acid concentrations hematocrit values were higher than those of patients who were not substituted. Folic acid concentrations in patients not substituted. Folic acid concentrations in patients not substituted were subnormal and further decreased on dialysis. Results of folic acid determinations in plasma were paralleled by concentrations in erythrocytes. It is concluded, that folic acid substitution is necessary in patients on hemodialysis.
