Transfusion Reaction Investigation

Test description

A laboratory clerical check of all documentation relating to the pre-transfusion sample is performed. Pre and post- transfusion venipuncture samples are visually inspected and compared for the presence of hemolysis. Preliminary tests may include the determination of patient's ABO group, DAT and a screen for the detection of atypical antibodies. Additional testing is performed based on the patient’s clinical symptoms and/or laboratory findings.
