Key facts

• B cell+T cell crossmatch.autologous [Interpretation] Qualitative by Complement dependent cytotoxicity
• B cell+T cell crossmatch.autologous
• Testing of autologus cells provides data that can sometimes help in interpretation of results obtained from testing patient's serum with the donor's T and B cells. Sometimes there is "non-specific" reactivity that if seen with the autologous cells would be an indication that the reactions with donor cell might lack clinical significance.
