Most plasma facilities automatically reject anyone who uses syringes for medication (or, a pump) because that puts them in a "high risk group". Type 2 diabetics (oral meds only) have to pass a urine dip the day of donation.View Thread
I test on my palm instead of fingers. I use the bottom corner away from the fingers opposite from my thumb where it's nice and meaty, and I use the tip that is supposed to be for arm testing. If you apply a bit more pressure before and after you stick, the blood flows out at a pretty good pace. It really doesnt work with the normal tip because it causes the blood to smear.
I also use hand lotion with parafin in it every night, and that tends to keep the skin very soft and supple.View Thread
