🩸 ABO Blood Group & Rh Typing
Aspect | Details |
|---|---|
Fasting Required? | ❌ Not required |
Sample Type | Blood (EDTA or plain) |
Organs Involved | Circulatory system (red blood cells, immune system) |
Purpose | To determine a person’s blood type for transfusions, pregnancy, or medical procedures |
🧬 What Is the ABO Blood Group System?
The ABO system is based on the presence or absence of A and B antigens on the surface of red blood cells:
Blood Type | Antigens on RBCs | Antibodies in Plasma |
|---|---|---|
A | A | Anti-B |
B | B | Anti-A |
AB | A and B | None |
O | None | Anti-A and Anti-B |
- The plasma antibodies play a vital role in determining compatibility for blood transfusions.
🔁 What Is Rh Typing?
The Rh system classifies blood based on the presence (+) or absence (−) of the Rh(D) antigen on red blood cells:
Rh Type | Rh (D) Antigen on RBCs |
|---|---|
Rh Positive | Present |
Rh Negative | Absent |
🩺 Why It’s Important
Clinical Use | Relevance |
|---|---|
✅ Blood transfusions | Prevents hemolytic transfusion reactions |
✅ Organ/bone marrow transplant | Compatibility check |
👶 Pregnancy | Prevents Hemolytic Disease of the Newborn (HDN) in Rh-negative mothers |
💉 Medical emergencies/surgery | Immediate access to blood group for safe transfusion |
🚨 Hemolytic Disease of the Newborn (HDN)
Occurs when an Rh-negative mother carries an Rh-positive fetus:
- The mother produces anti-Rh antibodies after exposure to fetal blood.
- In subsequent pregnancies, these antibodies can attack the baby's red cells.
- Prevented with anti-D immunoglobulin (Rhogam) injections during and after pregnancy.
🧪 Test Procedure
- A blood sample is drawn.
- Mixed with anti-A, anti-B, and anti-D (Rh) reagents.
- Agglutination (clumping) is checked to determine blood group and Rh factor.
