I have been a platelet donor in the past in the NY/NJ area, but none of the drives bring their platelet equipment with them. The closest platelet donation center is 50 miles away (100 mile round-trip) so that is not an option unless I'm in the area for some other reason. Most of these blood centers have regularly-scheduled whole-blood drives within 10 miles of me. Yet I attempt to go online or call them to schedule platelets at these drives and they never have platelet equipment available. I don't know if it's because the equipment is so fragile that it can't withstand the trip or what (one of the phlebotomists said the machine can make a real mess when it malfunctions). I can give platelets once a week; I can only give whole blood 4 or 5 times a year, yet all the blood centers here frustratingly complain that, "we need more platelet donors". The bottom line is the logistics make it impossible to give platelets.
