Establishment of an immunoglobulin A–deficient blood donor registry with a simple in‐house screening enzyme‐linked immunosorbent assay

Abstract

With a simple in-house ELISA, 73 blood donors were identified as IgA-deficient. From this number, 34 donors, without detectable anti-IgA in their plasma, were added to our IgA-deficient blood donor panel to maximize the management of our inventory of IgA-deficient frozen blood components.
