Overview
Laboratory Findings
Electrolyte and Biomarker Studies
Sedimentation rate is very high in most of the patients, but may be normal in approximately 20% of cases.
Biopsy
The gold standard for diagnosing temporal arteritis is biopsy, which involves removing of a small part of the vessel and examining it microscopically for giant cells infiltrating the tissue. Since the blood vessels are involved in a patchy pattern, there may be unaffected areas on the vessel and the biopsy might have been taken from these parts. So, a negative result does not definitely rule out the diagnosis.
