Update Date: 2024-07-23 Source: Network

Patients with ankylosing spondylitis (AS) can undergo physical examination, laboratory tests, and imaging studies, etc. I. Physical Examination:

1. Height and Weight: Measure the patient's height and weight and calculate the BMI index. If the BMI index is too high, it indicates a risk of obesity.

2. X-ray Films: X-ray films are one of the important methods for diagnosing AS, which can reveal blurred or disappeared sacroiliac joint spaces and narrowed intervertebral foramens.

3. C-reactive Protein (CRP) Test: CRP is an inflammatory marker that plays an important role in the pathogenesis of AS. Elevated CRP levels indicate active inflammation.

II. Laboratory Tests:

1. HLA-B27 Gene Test: HLA-B27 gene is closely related to the occurrence of AS, so performing an HLA-B27 gene test helps in confirming the diagnosis.

2. Blood Routine Test: By observing changes in indicators such as white blood cell count and neutrophil ratio, it can be determined whether there is an infection.

III. Imaging Studies:

1. CT Scan: CT scan can clearly show the pathological changes of the sacroiliac joint, such as bone destruction and soft tissue swelling.

2. MRI Examination: MRI examination is of great significance for early detection of inflammation at ligament attachment points and can be used as the preferred examination method.

In addition to the above tests, arthroscopy and pathological examination can also be performed. It is recommended that patients seek medical attention and treatment promptly.
