Here is what the lab wrote: Vitamin B12 - 710 (H) (lab range 221-700pg/mL)
I don't know enough about it myself.

Does anyone here have solutions/remedies for the itch? I feel like I'm going crazy from it! It wakes me in the middle of the night, I've got deep scratches on my arms and legs... I thought it might be a food allergy to eggs, but I haven't had eggs or chicken since sunday, and my itch that was gone has come back today so I have to assume it's from the SFN? (It's not from lymphoma, I just had CT scans to check for that.)

I looked through some of the stickies, but I'm raising my 3 yr old granddaughter so don't have a lot of free time. It will take me a little while to get through it.
Thanks!
