  • Dicarboxylic acids and correlated compounds as a measure of red blood cell quality
    Patent number: 11693018
    Abstract: Methods for testing a red blood cell (RBC) unit for release for transfusion into a subject are described. The methods allow management of the blood supply by assessing the viability of an RBC unit by its levels of dicarboxylic fatty acids (DFA). The methods include testing an RBC sample from an RBC unit for levels of DFA and discarding the RBC unit or releasing or not releasing the RBC unit for transfusion based on the results.
