Objectives
• Compare and contrast acute versus delayed transfusion reactions
• Look at the lab values associated with delayed transfusion reactions
• Discuss mixed-field reactions associated with delayed transfusion reactions

Laboratory tests to consider
• Direct Antiglobulin Test (DAT)
– IgG
– Complement
– Medications
• New Antibody Identified
– Eluate
– Kidd system
• Titers fall quickly

Laboratory tests to consider (cont.)
• Bilirubin – Increased due to RBC destruction
• liver disease, such as hepatitis
• hemolytic anemia
• cirrhosis, scarring of the liver
• biliary stricture, where part of the bile duct is too narrow to allow fluid to pass
• cancer of the gallbladder or pancreas
• gallstones
• drug toxicity

Laboratory tests to consider (cont.)
• LDH – Increased due to RBC destruction
• blood flow deficiency • cerebrovascular accident • certain cancers • heart attack • hemolytic anemia • infectious mononucleosis • liver disease • muscle injury • muscular dystrophy • pancreatitis • tissue death • use of alcohol or certain drugs • sepsis and septic shock

Case Study 1
• 38 year old female
• O Positive
– Received 2 units O Pos on 4/29
• New Specimen Drawn 5/11 showed Anti-Jka
– 1 Jka negative unit was given

Case Study 1 (cont.)
• Delayed transfusion reaction workup showed
– negative DAT
– no visible hemolysis
– one of the units the patient had received on 4/29 was Jka positive
– Reticulocyte harvest showed negative for the Jka antigen

Case Study 2
• 67 year old female
• A Neg
– Switched to Rh Positive units per pathology
• Decreasing RBCs post surgery
• Emergency uncrossmatched units ordered just after specimen expired at midnight for code
• 4 uncrossmatched units O Pos issued
