Background: Increasing demand of single donor platelet requires blood banks to expand the donor pool. A reassessment of donor deferral criteria for plateletpheresis is required to ensure that this increasing demand is met without compromising on product quality and donor safety.
Aims: (1) To list the various causes of SDP donor deferral.
Objective: This study was conducted to estimate prevalence of direct antiglobulin test (DAT) positivity and its impact on transfusion support in patients with thalassemia.
Methods: The DAT testing was performed for patients with β-thalassemia who received transfusion from November 2021 to March 2022. Elution was done for DAT-positive samples.
