My plasma donation the week before last went pear shaped - around 3/4 of the way through the machine shut down on a high pressure return and pushed some blood out around the needle so they had to stop. No idea what caused it but it did make a nice mess. I didn't notice unitl I felt something running down my arm and then the machine started beeping frantically.

The guy next to me looked worse off than I did though - he passed out at the end of his donation so was lying on the chair a bit woozy with a Doctor and Nurse tending to him.

As it didn't complete its cycle and I didn't get the saline at the end it's treated like whole blood donation and I can't donate anything for 3 months now.

Still, there was plenty there to use for someone so not wasted and I'll be back as soon as I'm able.
