Hello, this is my question. I am a regular plasma donor at a facility here where I live. Every 4 months they take a blood sample to be sent off for a protein analysis, it usually takes 10 days to get the sample back. Normally I know when the sample will be taken so I take 10 days off from donating at all before and the sample always comes back fine (because I am older, 40, weight 153 and I guess donating lowers my protein levels). I have had 2 samples come back recently with a protein of 5.9 (needs to be 6.0 or higher) and I am wondering what it is I need to be doing/and or changing to ensure that my levels are in range. Also, how is this different from the screening test they do every time I go in to donate to test my microhemocrotit? I have been out of range a couple times recently on that and was told to eat iron-rich foods. I am now including an iron supplement with my daily vitamins. I would appreciate any help or advice you could give, I am frustrated. Thank you!
