How to diagnose costochondritis
Costochondritis can be diagnosed through physical examination, imaging studies, and laboratory tests, which also help assess the severity of the condition.
1. Physical Examination
Costochondritis typically causes swelling of one or more costal cartilages, accompanied by local pain and tenderness. When these signs are identified during physical examination, a preliminary diagnosis of costochondritis can be made.
2. Imaging Studies
It is recommended to perform imaging tests such as chest X-ray, chest CT, ultrasound, or magnetic resonance imaging (MRI) under the guidance of a qualified physician to confirm the diagnosis, evaluate disease severity, and differentiate it from other conditions.
3. Laboratory Tests
Blood tests including white blood cell differential, rheumatoid factor, erythrocyte sedimentation rate (ESR), and serum calcium levels can help determine the extent of infection and differentiate costochondritis from rheumatic or autoimmune diseases. In costochondritis, white blood cell count and C-reactive protein (CRP) levels are often significantly elevated.
In addition, electrocardiogram (ECG) testing may be performed under medical supervision to rule out cardiovascular conditions such as acute myocardial infarction.
