As far as labs go... Quest admitted to using wrong calibrations for a YEAR in testing Vit D levels. All their tests for everyone were in error for a whole YEAR. So one cannot rely on tests 100% for anything IMO.
B12 is stored in the liver. So some of it may be going there to make up lost stores. It is also transferred into the CSF...cerebralspinal fluid to go around the spinal cord and into the brain. Blood work is for serum, only and does not reflect what is happening in the tissues of the body. Only what is floating around at that time "loose".
You are not back to where you were...and that is the good part.
As your body, gobbles up the B12, there are bound to be temp changes in blood level. If this concerns you alot...take an extra one 3 times a week, at 2 a day... and see if that changes things.

Thanks for the words of encouragement Mrs D. It worries me because when I was getting the injections, my numbers consistently went up. When I stopped & went to supplements, they went down. It took me months to get them up to 500 so I worry that I could continue to slide backward & then have to spend months getting it back up again. I wouldn’t be so concerned except that I continue to suffer from Neurological symptoms, fatigue, etc.
