Congrats on the overall good results, Lex.
RDW 15.9 (reference range 11.0 - 15.0 %)
MCV 89.5 (80.0 - 100.0 fl)
Lex, has your folate level ever been checked? High RDW with normal MCV can be caused by the beginning stages of a decrease in folic acid in the body (WHAT CAN CAUSE THE RED CELL DISTRIBUTION WIDTH TO BE TOO HIGH?
http://www.medfriendly.com/redcelldistributionwidth.html). Interestingly, Danny Roddy, Mel of ZIOH and Todd of the Dirty Carnivore forum all reported experiencing scurvy-like folic acid deficiency symptoms, or even diagnosed folic acid deficiency (as I noted about Mel here -
http://www.rawpaleodietforum.com/journals/lex's-journal/msg77597/#msg77597) on all-pemmican diets (folic acid deficiency symptoms are quite similar to scurvy symptoms). You don't eat all pemmican, but you do eat some, as I understand it, and eat an all-meat diet.
Natural folate is much better than folic acid, and is best obtained from food. Natural folate is associated with reduced risk of high-grade prostate cancer (Folate intake and prostate cancer risk: a case-control study,

http://jnci.oxfordjournals.org/content/101/6/432.abstract), whereas high-dose synthetic folic acid supplements are associated with INCREASED risk of prostate cancer (

Folate-rich foods like green vegetables, peanuts and beef liver
(

On the other hand, these studies associated folate with higher PSA, but don't say whether the folate was from food or what:
