Haptoglobin concentrations in children aged 9-10 years and its correlation to indirect parameters of erythrocyte turnover.

Low serum haptoglobin values are often found in children. Nine different parameters were studied in 125 healthy children aged 9-10 years to get indirect information on erythrocyte turnover and its possible relation to the low mean plasma haptoglobin level in childhood. The mean LD activity was higher than in adults.
