title: Serum ferritin estimation in blood donors subject to apheresis on IBM 2997 cell separator.
abstract: The serum ferritin concentration was tested in blood donors selected for apheresis on IBM Cell Separator. Of 41 donors, 28 were males and 13 females. All donors exhibited normal hemoglobin and RBC. The mean value of serum ferritin was 90.93 ng/ml in males and 48.38 ng/ml in females. In males--often with repeated blood donations--a low value of serum ferritin suggesting reduced Fe stores in organism was found in one individual only. In contrast, reduced serum ferritin levels were observed in 4 females who, before apheresis, regularly donated blood or had several pregnancies in their anamnesis. The obtained results point to prelatent or latent sideropenia. Serum ferritin concentration was measured in 18 donors selected for apheresis. The examination of ferritin was performed prior to, immediately after, and one week post separation. No significant changes in serum ferritin concentrations due to the separation procedure were observed. Preventive tests of serum ferritin in multiple blood donations and in women with previous pregnancies are recommended.
