My 10 yr old daughter displays signs of B12 deficiency- pins & needles up to 4 times a day, fatigue, unable to get to sleep, slight anxiety, loss of appetite, family history of autoimmune disease (PA & Hashis)
Her serum B12 is 402 (180-900) and ferritin is 39 (10-200). Other results are:
Vit D 115 (>50 is sufficient)
Transferrin saturation index- 30 (16-50)
Serum transferrin 2.75 (2-4.1)
Serum iron 18.3 (11-30)
Serum folate 9.4 (3-20)
Nucleated red blood count 0 (0-0.5x10*9)
GP was reluctant to take things any further but has now suggested a referral to a neurologist.
My question is- can my daughter start supplementing B12, a good B complex and some iron at home (GP said go ahead) while we wait for the neurology appointment (which will probably be a few months) or will this skew any future tests? (I would get her active B12, MMA and homocysteine myself done at St Thomas's but they won't deal with under 18s.)
I'm new to all this and don't have PA so any advice much appreciated as my knowledge is fairly sketchy.
Thank you in advance
