Washed Red Blood Cells would be the product of choice for a patient with:

Washed Red Blood Cells are particularly suited for patients with Anti-IgA antibodies. In this context, patients with such antibodies are at risk of developing severe allergic reactions when exposed to plasma proteins from red blood cell transfusions, including IgA. Washing the red blood cells removes a significant portion of the plasma and, consequently, the IgA, which minimizes the possibility of an adverse reaction.

This approach ensures the safety of the transfusion for patients with Anti-IgA antibodies, who would otherwise be at risk for anaphylaxis. The removal of plasma proteins through the washing process is crucial in providing a safe transfusion, allowing the patient to receive the necessary blood components without the risk associated with their pre-existing antibodies.

While the other conditions listed may warrant specific transfusion strategies, they do not necessitate the same level of intervention as seen with the presence of Anti-IgA antibodies.
