Answer

Answer

Biopsy is contraindicated in patients who have already undergone prolonged treatment with glucocorticoid therapy. While no consensus exists for the exact time course for temporal artery biopsy in this situation, data suggest that the diagnostic yield greatly decreases after 30 days of corticosteroid therapy. [8]

A relative contraindication is having already had a negative result from a biopsy that was properly performed. The rate of a positive contralateral biopsy in these cases is approximately 1%. [9]
