sorry i was actually reading the line above the b-12. my b-12 level is at 576. i freaked when i just read your post and looked over it again. so right now the only concern is my abnormal protein in the blood. also as a side note i dont know if this has any involvement but my dads 2 brothers both died of lymphoma and my dads mom died from cancer also. i believe hers was a blood cancer too. i hope i didnt inherit a cancer from them.
