The pregnancy is usually the one thing that is promptly checked when a young man fills a form as a blood donor where I live. The form is a table, most questions are yes/no with a separate column you mark with X. The pregnancy row has a twist, it's "fill if you are a women" type. Thankfully nurses know that well, check it instantly and ask to actually read the form. Blood donations are usually fun.
