Ankylosing Spondylitis

What are the different types of ankylosing spondylitis tests used to screen, diagnose, and monitor the condition? 
 
The Ankylosing spondylitis tests can give you an accurate reading of your markers for inflammation, including Antinuclear antibodies (ANA) and elevated C-reactive protein (CRP) levels.

: Blood

The HLA-B27 Antigen Test detects the presence of the HLA-B27 protein on white blood cells. This marker is linked to certain autoimmune disorders, including ankylosing spondylitis, reactive arthritis, and other inflammatory conditions. The test helps support diagnosis when symptoms suggest these diseases.



: Blood
Also Known As: Complete Blood Count Test, Total Blood Count Test, Hemogram test

The Complete Blood Count (CBC) with Differential and Platelets test measures red and white blood cells, hemoglobin, hematocrit, platelets, and white cell types. It helps detect infections, anemia, inflammation, immune disorders, and blood cancers, and assesses oxygen delivery, immunity, and clotting.


: Serum
Also Known As: CRP Test, Inflammation Test

The C-Reactive Protein (CRP) test measures the levels of C-reactive protein, a substance produced by the liver in response to inflammation in the body. It is a non-specific marker of inflammation and is used to evaluate the presence and intensity of inflammation. The CRP test helps healthcare providers assess the severity of an inflammatory condition and monitor response to treatment.

: Blood
Also Known As: Erythrocyte Sedimentation Rate Test, ESR Test, Sedimentation Rate Test, Westergren Sedimentation Rate Test

The Sed Rate (Erythrocyte Sedimentation Rate) test, also known as the ESR test, measures the rate at which red blood cells settle to the bottom of a tube over a certain period of time. It is a non-specific test that provides information about the presence of inflammation in the body.


Ankylosing Spondylitis affects approximately 0.2-0.5% of the population in the US. There is a prevalence of Ankylosing Spondylitis in patients who are positive for the HLA-B27 gene. 

The precise cause of Ankylosing Spondylitis is currently unknown. There are ongoing advancements in research, as well as Ankylosing Spondylitis tests. This helps to better understand this inflammatory disease and treatments.

What Is Ankylosing Spondylitis?

Ankylosing Spondylitis is a long-term, chronic condition. It causes inflammation in the spine and other parts of the body.

Over time, the inflammation can cause new bone to form. This can lead to the small bones in your spine fusing, causing pain, stiffness, and hunching.

Symptoms can start in teenagers and early adults. This inflammatory disease is more common in men than ... See more
