An immunoenzymatic assay (Epo-Eia) has been used in order to evaluate
the seric Epo level in beta-thalassemic heterozygous subjects. The pre
sent results lead one to conclude that serum Epo levels in thalassemic
subjects are higher than in normal subjects and that the differences
between thalassemic and normal females are highly significant statisti
cally (p<0.01). The Epo levels in thalassemic females are also higher
than those in thalassemic males (0.01<p<0.05). Differences in Epo leve
ls may be observed between thalassemic and normal males although they
are not highly significant statistically. No correlations seem to exis
t between Epo and Hb values.
