HLA-B27 antigen

What is HLA-B27 Antigen?

The HLA-B27 Antigen is a protein found on the surface of cells in the body. It is also known as Human Leukocyte Antigen, or HLA. HLA-B27 is one of several different antigens in the HLA family. It is an important part of the body’s immune system and is used to recognize “self” from “nonself” – useful for recognizing invading organisms like bacteria and viruses.

Purpose of HLA-B27 Antigen Test:

An HLA-B27 Antigen test is used to identify people with a predisposition to autoimmune disorders such as ankylosing spondylitis and inflammatory bowel disease. It can provide helpful information for predicting or diagnosing these disorders, and can help assess a patient’s risk for developing them.

Preparation for HLA-B27 Antigen Test:

There is no special preparation required for the HLA-B27 Antigen test. All that is required is a blood sample.

Procedure for HLA-B27 Antigen Test:

The procedure for the HLA-B27 Antigen test is simple and quick. A blood sample is taken from the patient and sent to a laboratory for analysis. The laboratory examines the blood sample to determine the presence or absence of the HLA-B27 Antigen.

Types of HLA-B27 Antigen:

There are three types of HLA-B27 Antigens – A, B, and C. Each type is associated with a different autoimmune disorder. For example, HLA-B27 type A is associated with ankylosing spondylitis, HLA-B27 type B is associated with inflammatory bowel disease, and HLA-B27 type C is associated with psoriatic arthritis.

Risks of HLA-B27 Antigen Test:

The HLA-B27 Antigen test is a low-risk procedure. The only risks associated with it are those associated with having a blood sample taken. These can include bruising, infection, pain, and dizziness.

Why Get Tested for HLA-B27 Antigen?

The HLA-B27 Antigen test is useful for predicting or diagnosing autoimmune disorders such as ankylosing spondylitis and inflammatory bowel disease. It can also help assess a patient’s risk for developing these disorders.

When to Get Tested for HLA-B27 Antigen?

The HLA-B27 Antigen test can be performed at any time. If a patient is experiencing symptoms of an autoimmune disorder, the doctor may recommend the test, as it can help make a diagnosis or assess the patient’s risk for developing an autoimmune disorder.
