Hi all, I thought my b12 deficiency was dietary as I've been vegetarian 22 years but I started self injecting with 1mg hydroxycobalamin alternate day loading doses 7 weeks ago and I still find I need it every other day to function. Also my serum level was never that low (550) when I started self injecting so I'm now suspecting it's functional and potentially pernicious anaemia. I just can't bear to stop as I get worse so rapidly. I've read on here about there being a more modern test for IF antibodies that's not affected by b12 supplementation. Doors anyone know the name of this type of test and even better, somewhere I can pay privately in the UK? I checked with medichecks who contacted the Doctors Lab and they confirmed they're using the test that needs you to lay off supplementing for two weeks.
Also, if this is pernicious anaemia rather than a dietary deficiency, do you ever hit the point where your levels build up and you can reduce the frequency? Can anyone give me reassurance that this level of frequency is OK and normal for some people? Cheers guys
