The growing practice of dialyzer reuse in recent years is mainly based on medical and economic considerations. However, adverse reactions such as immunohemolytic anemia due to anti‐N from antibody associated with dialyzer reuse have been reported. In this study, scanning electron microscopy and cytologic staining were used to evaluate the interaction between blood components and the reprocessed synthetic dialyzer membrane (polysulfone) after disinfectant (formaldehyde) treatment. The results showed that various blood components such as fibrin and blood cells still adhered to the dialyzer membrane after reprocessing. The study also demonstrated that the adhered denatured blood components could be detached by sonication andlor simulated hemodialysis and then gain access into the circulation. The re‐entry of the denatured blood components to the patients exposed to reused dialyzers may result in an enhanced imrnunological response which may contribute to antibody formation (such as anti‐N from antibody) with a reused hemodialyzer.
