The timing of gamma irradiation influences in vitro characteristics of red cell concentrates (RCCs), according to a new study. The research showed that RCCs sustain more damage the longer they are stored prior to gamma irradiation and the longer they are stored after irradiation. However, RCCs from female donors appeared to... [Read Article]

A newer, more streamlined apheresis system yields more CD34+ cells from stem cell transplant donors than a previous system, according to a new study. Researchers used both tools—the COBE Spectra Apheresis System and the Spectra Optia Apheresis System—to collect mononuclear cells (MNCs) from healthy donors and found the collection...

Data from the STRIDE study have revealed interventions that can mitigate iron deficiency in repeat blood donors. The study showed that providing repeat blood donors with iron supplements significantly improved their iron status. But informing donors about their ferritin levels and recommending they take iron pills also significantly improved their iron... [Read Article]

A new assay can detect and classify direct oral anticoagulants (DOACs) quickly and effectively, according to researchers. In tests, the assay detected DOACs with greater than 90% sensitivity and specificity. The assay classified the direct thrombin inhibitor (DTI) dabigatran correctly 100% of the time... [Read Article]

Interim results of a large study suggest a blood donor’s genetic background and frequency of donation influence red blood cell (RBC) storage and stress hemolysis. Investigators found that donor ethnicity and gender both affected hemolysis, but the effects sometimes differed between storage and stress hemolysis. Similarly, RBCs from frequent donors were more...
