Zinc levels of serum, hair and urine in homozygous beta-thalassemic subjects under hypertransfusional treatment.

The concentration of zinc in serum, hair and urine has been examined in 92 homozygous beta-thalassemic and 81 control subjects. The results were not statistically different in the subjects of each group studied (thalassemic and control persons of different ages: 1-12, 12-18, and 18-35 years).
