Hi,

I need to know if medication concentration levels are affected by donating plasma. It seems to me that if this is true, than anyone on any kind of medication, would not be allowed to donate plasma. Is there any research on the web that can point this out? I have searched and cannot find anything. Any help would be greatly appreciated.

I want to donate plasma, but my doctor believes that it would affect my medication levels and has told me that if I can find research showing otherwise, than I could donate.

Thanks again, I am on a

The plasma center is the one that can best tell you if you can donate or not, as they screen you via blood sample first. Most meds are not safe to be a donor. You would do better contacting donor centers for more info. Your doctor is correct though as plasma or blood levels, can drastically affect the medication dose, and be rendered useless. Just talked to my own doctor about it, and that was his opinion.

Thanks Talaniman, I have contacted the plasma center and they say they need confirmation from my doctor before proceeding. She says that she doesn't know of any tests performed after giving plasma to see what the mediciation levels are at and won't let me donate unless I can find some answers. But, thank you.

Sorry, but the tests she is referring to can be done in a lab, and is expensive, but you can look up the medication in question, and cross reference it with the dosage, and body weight, and half life of the med, to get a rough idea as to the levels at specific times. This is a safeguard for the donor, and all those who will receive the plasma, set by the FDA. That's why your doctor has the power to nix any donations, and well he should.
