I had a rushed but good conversation with GP.
He says my b12 has been about 200 since 2015!! I didn’t even know it had been tested before. In December 2017 b12 was 175.
Since I have autoimmune thyroiditis I asked to be tested for PA. He agreed and ordered intrinsic factor antibodies test.
Is testing for gpc antibodies necessary in this case?
I know sometimes you can be positive for gpc but not IFa, but is this true the other way round? If I’m positive for IFa then surely gpc is irrelevant. If I’m negative for IFA then I could still be positive for gpc? Autoimmune gastritis?
He agreed to b12 injections, but if I have them done will this affect gpc antibody testing in future ?
Thanks in advance- I’m kicking myself for not clarifying with him but every time I kept mentioning gpc he kept nodding and repeating IFa back to me.
