Diagnosing Temporal Arteritis (Cont.)

 
Temporal Artery Biopsy
Because of the possibility of permanent blindness, a temporal artery biopsy is recommended if there is any suspicion of temporal arteritis.
 
In a person with temporal arteritis, the biopsy will show abnormal cells in the artery walls. Some patients showing symptoms of temporal arteritis will have negative biopsy results. In such cases, the doctor may suggest a second biopsy.
