Harr ISBBWhat type of serological testing does the blood bank technologist perform when determining the blood group of a patient? A. Genotyping B. Phenotyping C. Both genotyping and phenotyping D. Polymerase chain reaction B Phenotyping, or the physical expression of a genotype, is the type of testing routinely performed in the blood bank.
