Performing a phenotype on patient red cells can be utilised to confirm or rule out alloantibodies during antibody investigations. The patient must be proven to be negative for the antigen in order for the corresponding alloantibody to be produced. There are some exceptions to this general rule as autoantibody production is possible.
Please note: In addition all haemoglobinopathy patients require an extended phenotype or genotype to be performed.
