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.
