A preliminary laboratory evaluation reveals a hemoglobin of 7.6 g/dL (normal values for women range from 11.5 to 14 g/dL). The mean corpuscular volume (MCV) is 75 fl (normal: 80-100 fl). The physician diagnoses inflammatory bowel disease and refers her to a surgeon for a bowel resection. Based on this information, the surgeon decided to order additional pre-operative coagulation tests.

Is it appropriate to perform a CBC in this patient at this time?
