The use of a cell-permeant molecular probe to assay the presence, and monitor the production, of the reactive oxygen species, superoxide, in red blood cells (RBCs) is described. The assay is performed using electron paramagnetic resonance (EPR) spectroscopy and a cell-permeant hydroxylamine spin trap.

Therefore, measurement of reactive oxygen species can be used as an indicator of RBC quality at the time of donation and after storage.
