Could I get some help on hematocrit questions?

Maybe maybe not there are many people that donate a pint of whole blood and it doesn't budge after one donation. A double red blood cell donation is the sure way to knock it down

It will lower, guaranteed. Maybe not four percent, maybe not even two, but it does lower some with each pint.

I've honestly never donated before, but I'm not too concerned. I was planning to start the cycle in about a week and a half. Better get on this...

It's nota guarantee brother I am telling you from personal experience that a whole blood donation one time may not lower it. If it did for you great but I have donated before and had my hematocrit level not budge.

I'm going to try and donate tomorrow. From there, do you think it'll be good to go to blast?

I take that back, I am wrong. After reading a little on it I found that the hematocrit formula is 1% hematocrit=1ml of RBC/100ml of blood. So it is directly proportional and lower the volume of blood does not guarantee altering the proportion of RBC in the blood. Hope that clears things up for you too OP, you learn something new every day.

Yeah, no kidding! I sure do. Thanks to both of you guys. I appreciate it. If I do the double cell donation, what would the math be for that theoretically?

I don't think there are any guarantees on how much it would lower considering what I just learned. But the possibility is there so it's worth a shot. While I was researching I did read a study just now saying that bigger veins hold more RBC so it is dependent on a lot of variables on how much it lowers.

I was reading a lot on what the "normal" ranges are when it comes to hematocrit. I saw one site say how the ranges for an adult male was 44%-54%, which seems a little out there. I also saw another one out there saying 38-51%, and my lab slip had 37-50%, so they are kind of all over the place.

They are all over the place but most trt dr's will try to keep it below 50

Certainly doing the double red blood cell is going to have a better chance of lowering it because they are filtering out red blood cells only for the donation. That is what you need lowered. When you donate whole blood you are just donating whole blood.

Okay, great. Sorry, stupid question here, but when I donate tomorrow, I request to have a double RBC donation? Just like that?

Thanks
