I was deferred from donating blood this morning. I had even
gone online and searched for info about donating eligibility if you have stitches but could find nothing. So I showed up. "Yes. I feel well." (I do.) And then at the end of the screening, when they ask if I have any questions, I ask about the stitches. Deferred.
They should put it in the literature somewhere if it means you can't donate. Wasted 30 minutes and took up a donation slot somebody else could have filled.
Apparently if I said I didn't feel well, there was a sub-menu that gave me the stitches option to check off.
