That’s because the blood serum result can contain up to 80% inactive B12 , which cannot be absorbed by our cells . The active test is more accurate .
I had the active b12 done with medichecks….the serum b12 was nhs.
Doctor didn’t seem that concerned.Don’t know what to do really
Well do you have B12 deficiency symptoms ? If you do , your doctor should be concerned . You don’t mention any .
The serum test is cheaper . But some NHS surgeries do the Active B12 test . ..
The reason for your low B12 coupled with your symptoms must be found . The most common reason is Pernicious Anaemia , an autoimmune condition which must be treated with B12 injections FOR LIFE . I’m afraid that the medical profession is quite ignorant on this condition. That’s why this forum was started .
There are other reasons for B12 deficiency. Your doctor must find the reason .
What was your serum level? What was the normal range you used to assess it?
I hope that you get some help from your GP . Trouble is that the medical profession is mostly very ignorant on the subject of B12 deficiency. 🍀🍀
Hi, what is your Active b12 level?
It could be that the serum level is falsely reading high?
Before a functional b12 deficiency diagnosis I had a b12 serum level in high 400’s, few wks later itbwas tested and at 260 ish, and I’ve recently requested old notes and looks like it’s always been in 200’s in past, so think it was an inaccurate result.
The Active b12 is the best indicator especially if you have symptoms too. Or also, if you have a functional deficiency, it may well read high, but not necessarily be getting into the cells?
Have you had vitamin d, folate, iron, ferritin and full blood count recently? Hopefully your Dr will check all of these and be extremely helpful! But always remember the support you have on this site and if you share your results on here there’s always plenty who’ll help. Hope you soon get an apptment and a little bit further…😀
