Every 2 months. Have donated over 10 gallons over the years. Good
for you, good for the community. Win win.
Plus it keeps my hematocrit within a tolerable range. Donating drops
mine about 2 points. I'm around 50 when the test results come back.
(It's been 52 and then I donate and it comes back around 50.)
I have no clue what it is when the jab me. Am I scared of the worst
case scenario? I don't honestly have an answer for that.
I would be interested in what it would be a day or two after I donate
verses the day before I test. I usually do it somewhere in the middle.
Will see if I can arrange that.
