Anti B Titre Serum

Anti B Titre, Serum – Test Content

Test Name: Anti B Titre, Serum

Sample Type: Serum

Purpose of the Test:
The Anti B Titre test measures the concentration (titre) of anti-B antibodies present in the serum. These antibodies are naturally produced against the B blood group antigen in individuals who do not possess the B antigen on their red blood cells.

Why is this Test Done?

• Pre-transplant evaluation (especially ABO-incompatible organ transplantation)
• Assessment before blood transfusion
• Monitoring antibody levels during desensitization protocols
• Investigation of hemolytic reactions related to blood group incompatibility
• Research and immunohematology studies

Clinical Significance:

• High anti-B antibody titres may increase the risk of hemolytic reactions during incompatible transfusions or transplants.
• The test helps clinicians evaluate the strength of immune response against B blood group antigens.
• Serial monitoring may be required in transplant recipients to assess treatment effectiveness.

Preparation:

• No special preparation or fasting is required.
• Inform your healthcare provider about any recent transfusions, transplants, or immunotherapy treatments.

Methodology:

• Tube Agglutination Method / Column Agglutination Technology (as per laboratory protocol)

Report Delivery:

• Results are reported as the highest serum dilution showing detectable agglutination (e.g., 1:8, 1:32, 1:128).

Interpretation:

• Titres are interpreted in conjunction with clinical history and laboratory findings.
• Reference values may vary depending on the laboratory methodology and clinical indication.
