Hematocrit levels: what’s “high?”

[sirgawain]

Went today for my “every three months” blood “donation.” I was at 47. That doesn’t seem so high. When should I be worried?

I do 2x a week subq.

I wouldn’t donate with an HCT at 47, no reason for it, except to help others in need. Every three months, over the long term, you risk crushing your ferritin.

The ranges go up to 52%. I’ve had my HCT at 57% and no symptoms.

What’s high is relative, some men can’t handle anything 50%>.

47% perfect. I would not have donated blood unless you want to. I would donate at 50% but yes just me. I haven't donated now for over 6 years.

Not high at all, just keep an eye on it and make sure you stay 50 0r less.

my used to go up to 54 or so. donated only so docs dont yell at me at appointments cause the numbers look bad on them
i feel absolutely no difference in regards to those numbers. will still donate before blood draws for the sake of bureaucracy. and helping people in need isn't a bad thing either.

Mine is yelling at me at 50.4. Like you, I feel no difference at 50. than when I was at 58.

I agree that 47 is not a worry, not high enough to mandate phlebotomy,

i get symptomatic around 53, really feel it at 54, but I don't think though that waiting for symptoms to develop is a good plan. I try to keep it below 52, but my own case is messed up, complicated by things other than TRT. If my erythrocytosis was solely due to TRT I'd prefer to keep it below 50, and lower my testosterone dosage if possible to try to actually treat the cause, not just do phlebotomies as stopgap treatment of high HCT.

Also, in terms of donating blood, if you are able, and feeling altruistic, please do! I am alive because of transfusions, and the generosity of those who donate. Heartfelt thanks to all who do!

Mine stays 53-57. As high as 60 once. I can never tell with out labs, no symptoms. However, I was upper 40’s to 50 my entire adult life. So as already said, we are all different
