The Role of Joint Aspiration
Joint aspiration is the first line of action in diagnosing septic arthritis. This procedure involves using a needle to extract fluid from the affected joint, which is then analyzed for bacteria, white blood cells, and other markers of infection.
Analyzing the Joint Fluid
The extracted joint fluid is examined for bacteria through Gram staining and cultured to identify the specific organism. A high white blood cell count in the fluid usually indicates an infection, helping confirm the diagnosis.
Supporting Tests
While joint fluid analysis is key, blood tests and imaging like X-rays or MRIs are also used to support the diagnosis. These tests help rule out other conditions and assess the extent of joint damage.
