Grifols Daratumumab Neutralization Test

Grifols has added a daratumumab neutralization testing service to its menu offered at the Grifols Immunohematology Center laboratory in San Marcos, Texas. The test enables complete antibody screening and identification in pretransfusion testing of patients using daratumumab, a monoclonal antibody for the treatment of multiple myeloma. The test is based on a soluble recombinant human CD38 that neutralizes the therapy present in plasma and eliminates its interferences with routine pretransfusion testing, the company said.
