There seems to be an issue with too many platelet donors of certain blood groups. I was told a couple of months ago that I couldn't donate the week I wanted because "they had too many A+ already that week". The receptionist was also telling me about having to phone platelet donors to move appointments - or even cancel them - for the same reason. I would guess that we might start seeing another attempt to push platelet donors back to whole blood. It wouldn't be the first time, although the last was around 1998. Other than that I've not heard anything special about female donors. It might just be your clinic - they seem to get a fair amount of local management control.
My local clinic is also about to start collecting plasma as well as platelets on the same donation. The new kits are already being used, but they didn't open the plasma tap. I gather collecting plasma lowers the platelet yield a little, so it's most likely to be aimed at people like me who give a good double, but can't reliably provide a triple. The good triples will probably stay on platelets only. Again though, it may just be a local thing.
