T80.A9
Other non-ABO incompatibility reaction due to transfusion of blood or blood products
Clinical Classification Guidelines
Inclusion Terms
- Delayed serologic transfusion reaction (DSTR) from non-ABO incompatibility
- Other reaction to non-ABO incompatible blood transfusion
Medical Intelligence & Overview
ICD-10 code T80.A9 refers to other non-ABO incompatibility reactions caused by blood or blood product transfusions. Unlike reactions due to ABO blood group incompatibility, these reactions are related to other immune or non-immune factors. They can occur immediately or after some delay following a transfusion. Recognizing and managing these reactions is important for patient safety, but diagnosis and treatment should always be guided by healthcare professionals.
Causes & Symptoms
Clinical Causes: Delayed immune response to donor blood components Hemolytic reactions due to incompatibility outside ABO system, such as Rh, Kell, Duffy, or other blood group antigens Non-immune factors like bacterial contamination or storage-related issues in blood products Allergic reactions to plasma proteins or additives in transfused blood Transfusion-related iron overload or other metabolic reactions
Key Symptoms: Fever or chills Rash or itching Dark urine or hemoglobinuria Lower back or flank pain General discomfort, fatigue, or malaise Swelling or redness at the transfusion site Breathing difficulties in severe cases
Diagnostic & Treatment
Diagnosis Path: Reviewing the patient's transfusion history and timing of symptom onset Blood tests to detect hemolysis, such as a direct antiglobulin (Coombs) test Assessing blood samples for presence of donor-specific antibodies Repeat blood typing and crossmatching to identify incompatibilities Additional tests like complete blood count (CBC), bilirubin levels, and urinalysis for hemolytic markers
Treatment Protocols: Stopping the transfusion immediately Providing supportive care such as IV fluids and medications to manage symptoms Administering antipyretics or antihistamines for fever or allergic reactions Using corticosteroids or other immunosuppressants in certain immune-mediated reactions Treating complications such as hemolysis, organ damage, or infections as needed Reporting adverse reactions to blood banks and transfusion services for investigation and future prevention
