Frequently Asked Questions about HLA B27 (Human Leukocyte Antigen B27) - PCR

Q. How is the blood sample taken?

The healthcare provider takes a blood sample from the arm. The site from where the blood is to be withdrawn is cleaned with a swab of rubbing alcohol. This is then followed by inserting a small needle which has a tube attached to it for collecting blood. Once the sufficient blood for analysis is withdrawn, the needle is removed. The site is then covered with a gauze pad.

Q. Is there any risk associated with the withdrawal of blood sample procedure?

As such there is no risk but in few cases, bruising, bleeding, and infection at the puncture site can be seen. In very few cases, there can be swelling of the vein after the blood is withdrawn.

Q. What is Reactive Arthritis?

Reactive arthritis is a painful form of inflammatory arthritis. This includes joint disease caused due to inflammation. It develops due to inflammation caused in response to infection which is caused by certain bacteria which are present in genitals (Chlamydia trachomatis) or the bowel (Campylobacter, Shigella, Salmonella, and Yersinia).

Q. What is ankylosing spondylitis?

Ankylosing spondylitis is a form of arthritis that primarily affects the spine, but can affect other joints as well. It comprises of vertebrae (spinal joints) inflammation which can further cause severe, chronic pain and discomfort. If the inflammation is left unchecked, it can lead to new bone formation in the spine which is known as ankylosis. In ankylosis, sections of the spine fuse in a fixed and immobile position. In this, one can develop inflammation, pain and stiffness in other parts of the body such as hips, ribs, shoulders, heels, and small joints of hands and feet. The inflammation can also involve eyes, the condition is known as uveitis or iritis. Whereas, in rare cases, heart, and lungs can be affected.
