Can Anyone Please Advise On B12 related tests to have If Normal B12 Testing is in range.
My daughter is having numerous issues including IBS which she had for nearly 20 years and the last 18 months undiagnosed urology issues, mostly infections that often come back as no issues and has been on numerous different antibiotics and all her GP is testing for is the normal B12 test. Her folate has come back below 3 but the GP has not contacted her yet.
I think there are other tests to see if the B12 in her blood is being utilised but not sure what they are.
I have autoimmune Hypothyroidism along with a serious auto immune blood disorder and it is a good chance my daughter has inherited autoimmune issues.
The only results so far taken last week apart from FBC which came back all in range.
Folate 2.9 >3 was 3.8 in August 2023
B12 537 ng/l (200 - 771)
Ferritin 40 ug/l (13 - 150)
Thank you in advance for any replies.

Search online for this UK document "NICE CKS Anaemia - B12 and Folate deficiency" and read it thoroughly including the section on Background Information.
Try to find local B12 deficiency guideline used by ICB (Integrated Care Board) in England or Health Board in Wales/Scotland and compare it to NICE CKS document.
It's important that in a person with both folate and B12 deficiencies, the B12 treatment is started first. Treating folate deficiency without treating a co-existing B12 deficiency may lead to neurological problems.
See Cautions section in link below about Folic acid.
Thank you for the useful information, I have added the latest results and ranges to my original post. Is it likely the NHS will carry out MMA (Methylmalonic acid) and Homocysteine (tHCY) tests?
Is there a check list of possible symptoms for B12 deficiency by any chance that can be ticked off and presented to her GP.
I asked my GP to do MMA after I was advised by medichecks GP (paid for private blood test) to check MMA due to B12 active test on the low side. The request was refused due to her telling me she didn't have access to it. I've had to order it through medichecks. Worth asking though you might be lucky.
