I have just got my Active B12 result back from Blue Horizon, test was taken 25th Feb.
level 69 range 25.1 - 165.0
12th Feb. My serum level was 394 range 180.00 - 1130.00
I am also hypothyroid and taking levothyroxine.
I have recently developed pins and needles, tingling and a pricking sensations mainly in hands, feet and face but sometimes it is all over my body.
Blue horizon states on report in 'Result in range' but could anyone please comment on the level.
Many thanks browny
