Preparation for a core needle biopsy may involve fasting for a few hours prior to the procedure, depending on the area being biopsied. Patients should inform their healthcare provider of any medications they are taking, especially blood thinners, as these may need to be adjusted. Wearing comfortable clothing and arranging for someone to drive home after the procedure is also recommended. Nurses can aid in preparation by ensuring the patient understands these requirements and by verifying that all pre-procedure instructions have been followed.
