Question 1

What is Transfusion Reaction?

Accepted Answer

Transfusion reaction is an adverse immune response that occurs when the body rejects blood received during a transfusion. It is caused by incompatibilities between donor and recipient blood, primarily ABO blood group mismatches or Rh factor incompatibilities that trigger the immune system to attack foreign red blood cells. The ABO Grouping and Rho(D) Typing test is the most important test for preventing transfusion reactions by ensuring blood compatibility before transfusion.

Question 2

What causes transfusion reactions?

Accepted Answer

Transfusion reactions are caused by incompatibilities between donor and recipient blood that trigger the immune system to attack foreign blood cells. The most common cause is ABO blood group incompatibility, where receiving the wrong blood type (A, B, AB, or O) causes immediate and potentially life-threatening reactions. Rh factor mismatches, particularly when an Rh-negative person receives Rh-positive blood, can also cause severe reactions. Additionally, irregular antibodies developed from previous transfusions, pregnancies, or transplants can react against specific antigens on donor red blood cells, leading to delayed transfusion reactions that occur hours or days after the transfusion.

Question 3

What is the best test for transfusion reactions?

Accepted Answer

The ABO Grouping and Rho(D) Typing test is the most important test for preventing transfusion reactions because it determines your exact blood type (A, B, AB, or O) and Rh factor (positive or negative), which are the primary causes of severe transfusion reactions. This test ensures that you receive compatible blood that your immune system will not reject. The Antibody Screen, RBC with Reflex to Identification, Titer, and Antigen Typing is the best complementary test because it detects irregular antibodies in your blood that could react against donor blood, even when ABO and Rh types match. Together, these tests create a complete compatibility profile that prevents both immediate and delayed transfusion reactions, making blood transfusions safe by identifying potential incompatibilities before they can cause harm.

Question 4

When should I get tested for transfusion reactions?

Accepted Answer

You should get tested before any planned surgery or medical procedure where blood transfusion might be needed, so healthcare providers know your blood type in advance. Testing is essential if you have a history of multiple transfusions, pregnancies, or organ transplants, as these increase your risk of developing antibodies that could cause reactions. You should also get tested if you experienced symptoms like fever, chills, back pain, dark urine, or difficulty breathing during or after a previous transfusion, as these indicate possible transfusion reaction history. Additionally, if you are pregnant and Rh-negative, testing helps prevent reactions that could affect your baby during pregnancy or future transfusions.

Question 5

What are the symptoms of transfusion reactions?

Accepted Answer

Transfusion reaction symptoms vary from mild to life-threatening depending on the type and severity of the reaction. Immediate symptoms that occur during or within hours of transfusion include fever, chills, flushing, rapid heart rate, low blood pressure, back or chest pain, nausea, and difficulty breathing. Severe acute reactions can cause dark or bloody urine indicating kidney damage, jaundice (yellowing of skin and eyes), and bleeding problems. Delayed transfusion reactions that develop days or weeks later cause fever, jaundice, unexplained anemia, and fatigue as antibodies slowly destroy transfused blood cells. Any unusual symptoms during or after a transfusion require immediate medical attention to prevent serious complications.

Question 6

Who is at risk for transfusion reactions?

Accepted Answer

People who have received multiple blood transfusions are at higher risk because each exposure increases the chance of developing antibodies against blood cell antigens. Women who have been pregnant, especially multiple pregnancies, have increased risk due to exposure to fetal blood cells that can trigger antibody formation. Patients with sickle cell disease, thalassemia, or other chronic anemias requiring frequent transfusions face elevated risk of developing irregular antibodies over time. Organ transplant recipients and people with autoimmune conditions have higher risk due to immune system changes that make reactions more likely. Additionally, emergency transfusion situations where complete compatibility testing cannot be performed before blood administration significantly increase reaction risk.

Question 7

What happens if transfusion reactions are left untreated?

Accepted Answer

Untreated acute transfusion reactions can rapidly progress to life-threatening complications including acute kidney failure, which occurs when incompatible blood cells break apart and block kidney filtration systems. Severe reactions can cause disseminated intravascular coagulation (DIC), a dangerous condition where blood clots form throughout the body while simultaneously causing uncontrolled bleeding. Hemolytic reactions that destroy large amounts of red blood cells can lead to shock, respiratory failure, and death within hours if not immediately addressed. Even delayed transfusion reactions, when left unrecognized, can cause severe anemia, organ damage from prolonged low oxygen levels, and increased mortality risk. Proper pre-transfusion testing and immediate treatment of reactions are critical for preventing these potentially fatal complications.

Question 8

Can transfusion reactions be diagnosed with blood tests?

Accepted Answer

Yes, blood tests are essential for both preventing and diagnosing transfusion reactions through comprehensive compatibility testing and post-reaction investigation. Before transfusion, ABO blood typing and Rh factor testing identify your blood group to ensure compatible donor blood selection. Antibody screening detects irregular antibodies that could react with donor blood even when basic blood types match. After a suspected reaction, blood tests including direct antiglobulin test (DAT), comparison of pre- and post-transfusion blood samples, bilirubin levels, and kidney function tests confirm whether a reaction occurred and identify its cause. These tests detect evidence of red blood cell destruction, kidney damage, and specific antibodies responsible for the reaction, guiding treatment and preventing future reactions.

Question 9

How are transfusion reactions treated?

Accepted Answer

Immediate treatment begins with stopping the transfusion as soon as a reaction is suspected and maintaining intravenous access to administer medications and fluids. Healthcare providers give intravenous fluids to support blood pressure and kidney function, preventing kidney damage from hemoglobin released by destroyed red blood cells. Medications including antihistamines, corticosteroids, and epinephrine treat allergic and inflammatory symptoms, while fever reducers manage temperature elevation. Severe cases may require intensive care with respiratory support, dialysis for kidney failure, and blood component therapy to manage bleeding complications. Future transfusions require specially selected blood matched for the specific antibodies identified, and in some cases, washed or leukocyte-reduced blood products minimize reaction risk.

Question 10

How can I prevent transfusion reactions?

Accepted Answer

Prevention starts with proper pre-transfusion blood testing that identifies your ABO blood type, Rh factor, and any irregular antibodies you may have developed from previous transfusions or pregnancies. Always inform healthcare providers about your complete transfusion history, previous reactions, pregnancies, and any blood disorders that increase your risk. Maintain a personal medical record card with your blood type and any known antibodies for emergency situations. When possible, opt for autologous blood donation (donating your own blood before scheduled surgery) to eliminate compatibility issues entirely. Healthcare facilities prevent reactions through rigorous blood bank protocols including double-checking patient identification, careful donor-recipient matching, starting transfusions slowly while monitoring vital signs, and using leukocyte-reduced blood products that minimize immune responses.

Question 11

What can I do at home after a transfusion?

Accepted Answer

After receiving a blood transfusion, monitor yourself closely for delayed reaction symptoms including fever, yellowing of skin or eyes, dark urine, unusual fatigue, or unexplained bruising, and report any concerns to your healthcare provider immediately. Rest adequately in the days following transfusion to allow your body to adjust to the new blood cells and recover from the underlying condition that required transfusion. Stay well-hydrated by drinking plenty of water to support kidney function and help your body process any byproducts from the transfused blood. Avoid strenuous physical activity for 24-48 hours after transfusion to prevent complications. Keep all follow-up appointments where healthcare providers can check blood counts, kidney function, and signs of delayed reactions. Maintain detailed records of all transfusions including dates, blood products received, and any reactions experienced for future medical reference.
