About 40% of people will have other nonspecific symptoms such as respiratory complaints (most frequently dry cough) or weakness or pain along many nerve areas. Rarely, paralysis of eye muscles may occur. A persistent fever may be the only symptom.
Diagnosis & Tests
The doctor will examine your head. Touching the head may show that the scalp is sensitive and has a tender, thick artery on one side. The affected artery may have a weak pulse or no pulse.
Blood tests may include:
- Hemoglobin or hematocrit — may be normal or low
- Liver function tests — may be abnormal with high levels of alkaline phosphatase
- Sedimentation rate and C-reactive protein — almost always very high
Blood tests cannot specifically diagnose this condition. A biopsy and examination of tissue from the affected artery confirm the diagnosis in most cases.
