Mabel Adams 1,015 Posted June 11 We have a pancreatic cancer patient who swears he has never been transfused and doesn't appear to have had major surgeries that require transfusion but who has an anti-Fyb. No evidence of a source of passive antibodies. Negative antibody screen elsewhere in recent months. Are there reports of naturally occurring anti-Fyb?

Malcolm Needs ★ 4,359 Posted June 12 The only report I can find is Michalewska B. Naturally occurring anti-Fyb + Cw. Vox Sanguinis 2001; 80: 235. In this (which is a letter to the Editor, rather than a "paper"), the author writes about another unpublished observation cited in Issitt PD. Applied Blood Group Serology. 3rd edition. Miami. Montgomery Scientific Publications, 1985: 278. While I have a copy of this book, I can't get to it at the moment. I once came across a male patient with a very strong anti-Fya. He said that, despite fighting in the army and having undergone surgery, he had never been transfused. We didn't delve too deeply, as he was a Jehovah's Witness, but we were a little sceptical!
