Entirely fictitious donor history:
A female high school senior (age 17 years old) recently attended an educational session about blood donation by a blood donor center and has decided that she would like to donate blood for the first time. She presents at a blood drive at her local community center later that day. She is a marathon runner, 5'5" tall, and 110 lbs., and has a resting heart rate of 50 bpm. Her recent annual physical blood work showed a hemoglobin of 12.5 g/dL. She had a migraine yesterday and took Excedrin migraine (contains aspirin, caffeine, and acetaminophen) around 8pm yesterday. Additionally, she uses the topical acne medication, clindamycin-benzoyl peroxide and isotretinoin. She feels healthy, does not have any diagnosed medical conditions, and does not take any other medications.

Which of the following components in her history disqualifies her from whole blood donation at this visit?
