Yeah I hear ya. It's frustrating.
My doc is anal about this and takes me off until it comes down.
I don't seem to have it as bad as you, when I donate it usually falls below range. Except this time I couldn't get in to LifeLabs quickly enough after donating. They closed the closest location b/c of Covid, and other locations were totally swamped and I got turned away twice. Finally went to Dynacare and got in, but almost a week had passed and I was over again, and was told to stop. Fuuuuuck!
I've never seen 200, that sounds high, but FWIW, if you're going by pre-donation readings, those are not very accurate.
I'm thinking of seeking therapeutic phlebotomy if I have to wait too long. Maybe bribe my vet if I have to
Also begs a question for you and others: Are there any compounds that have little effect on hematocrit that could be used during these intervals? Sarms maybe instead?
