Task: Answer Verification
Input (English): Question: Is routine pre-procedure laboratory testing for patients undergoing outpatient cerebral angiography indicated?
Answer: The incidence of abnormal testing in patients undergoing outpatient cerebral angiography is very low. These results and evidence in the literature suggest that the majority of patients undergoing cerebral angiography do not require any pre-procedure testing. Assessment of renal function using the estimated glomerular filtration rate in high-risk patients only is, however, warranted.
Output (English): no
