ANTI-B ANTIBODY TITRE in Mahalakshmi-layout, Bangalore

Anti-B Antibody Titre Test: Price, Purpose, and Report Interpretation

Test Overview

Blood group compatibility plays a crucial role in safe transfusions, pregnancy care, and organ transplants. The Anti-B Antibody Titre test is a specialised blood test used to detect and measure the levels of Anti-B antibodies in an individual’s serum. These antibodies are produced when a person with blood group A or O is exposed to B antigens, either through transfusion, pregnancy, or transplantation. Monitoring Anti-B antibody titres helps ensure compatibility, prevent transfusion reactions, and manage conditions like haemolytic disease of the newborn (HDN).

Also known as the Anti-B Isohemagglutinin Titre test, it provides valuable information about immune sensitisation and blood group antibody strength. Whether it’s part of a pre-transfusion compatibility check, prenatal screening, or routine immunohaematology testing, this test ensures safer clinical decisions.

What is an Anti-B Antibody Titre Test?

An Anti-B Antibody Titre test is a blood test that measures the level (titre) of antibodies directed against B antigens in a person’s blood. These antibodies are part of the immune system’s natural defence mechanism and play a crucial role in blood group compatibility, particularly for individuals with blood group A or O. Essentially, the test helps determine whether anti-B antibodies (produced when your immune system recognises B antigens as foreign) are present and at what concentration. The results are expressed as a titre value, indicating the dilution level at which antibodies can still be detected. Doctors often recommend the Anti-B Antibody Titre test in blood transfusion compatibility assessments, pregnancy monitoring, or organ transplant evaluations to identify possible immune reactions between donor and recipient blood groups. This test panel includes three components:

• Anti-B Antibody Titre
• Anti-B IgM Titre
• Anti-B IgG Titre

Together, these tests provide a comprehensive evaluation of both immediate (IgM) and long-term (IgG) immune responses against B antigens.

What is the Anti-B Antibody Titre Test Price?

The Anti-B Antibody Titre test price varies depending on several factors such as location, laboratory quality, and whether it’s booked as a standalone test or part of a broader immunohaematology panel.

Key factors affecting test price:

• Geographical Location: Prices may differ between major cities and smaller towns due to operational and logistics costs.
• Laboratory Standards: NABL-accredited or high-end diagnostic centres may charge slightly higher prices due to advanced testing protocols.
• Panel Inclusions: When combined with other antibody screening tests or cross-matching profiles, the cost may increase.
• Promotions and Discounts: Apollo 24|7 frequently offers value-based packages and seasonal discounts that make the test more affordable.

What is the Purpose of an Anti-B Antibody Titre Test?

This test helps identify the strength and presence of Anti-B antibodies that could react against B antigens. Such reactions are crucial to evaluate before blood transfusion or pregnancy. Main purposes include:

• Blood Transfusion Compatibility: Ensures that the recipient’s serum does not contain antibodies that might attack donor red blood cells bearing the B antigen.
• Pregnancy Monitoring (Haemolytic Disease of the Newborn): In Rh or ABO incompatibility cases, the mother’s antibodies can cross the placenta and attack the baby’s red blood cells. Testing helps monitor maternal antibody levels.
• Pre-Transplant Screening: Prevents immune reactions during organ transplantation by identifying potential antibody-antigen incompatibility.
• Immune System Evaluation: Measures the body’s immune response to foreign antigens, especially in individuals with autoimmune or immunological disorders.

Who Should Get an Anti-B Antibody Titre Test Done?

Your doctor may recommend an Anti-B Antibody Titre test if you fall under the following categories:

• Individuals with blood group A or O, who are more likely to produce Anti-B antibodies.
• Pregnant women with suspected ABO incompatibility between mother and foetus.
• Patients undergoing blood transfusion to check for possible immune reactions.
• People scheduled for organ or bone marrow transplantation.
• Those who have experienced transfusion reactions in the past.
• Additionally, if a doctor suspects haemolytic anaemia, autoimmune reactions, or alloimmunisation, this test can provide critical diagnostic clues.

Components of the Anti-B Antibody Titre Test

The Anti-B Antibody Titre profile typically includes the following three tests:

1. Anti-B Antibody Titre

This measures the overall concentration of Anti-B antibodies present in your blood.

It helps determine the potential for an immune reaction if exposed to B antigens.

2. Anti-B IgM Titre

• IgM antibodies are immediate responders that appear early during an immune reaction.
• A high IgM titre indicates a recent exposure to the B antigen or an active immune response, which may be clinically significant in transfusion compatibility or acute reactions.

3. Anti-B IgG Titre

• 
  IgG antibodies represent long-term immune memory.
• A high IgG titre suggests previous sensitisation, often through transfusion, pregnancy, or prior exposure to incompatible blood. IgG antibodies can cross the placenta, making them crucial for pregnancy monitoring to prevent Haemolytic Disease of the Newborn (HDN).

Understanding the Anti-B Antibody Titre Test Report

The Anti-B Antibody Titre test results are expressed in titre values, which indicate the dilution ratio at which antibodies are still detectable.

Note: Reference values may vary depending on the testing laboratory and the technique used (tube, gel card, or automated systems).

Interpretation of Results

Here’s what the test result mean:

Note: Your doctor will interpret the titre values alongside your ABO blood group, Rh factor, and clinical history to determine the next steps.
