Surgical consultation is necessary for TAB. Depending on the institution, this procedure can be performed by a neurosurgeon, plastic surgeon, ophthalmologist, or general surgeon.

It is imperative that the treating physician be familiar and confident with the laboratory that is evaluating the TAB specimen, since this is the criterion standard for GCA diagnosis. A myriad of laboratory errors (eg, specimen handling, fixation, sectioning) can, if they occur, result in a misdiagnosis (most often a false-negative result).
