Whereas transfusing a 500 mL malaria-infected donor whole blood stored for 35 days could result in inadvertently infusing 90.2 ng or 73.7 ng of TNF-α and IL-12, respectively, transfusing an equivalent volume of nonmalaria-infected donor whole blood stored for 35 days may lead to infusing 32.4 ng or 11.1 ng of TNF-α and IL-12, respectively. The gene discussed is TNF; the disease is malaria.
