Hey guys,
I had a blood test done recently and got some of the normal tests done. I got a CBC and HGB/HCT came back normal and I got an MMA test done and it came back at 99 (0-378 normal) so all of that checks out.
This time though I did get a serum gastrin test for the first time. It came back at <10 (0-115 normal). I had fasted with water only for about 13 to 14 hours prior.
I guess this rules out PA for the most part and leaves my b12d reason as my strict vegan diet for 10 years correct? Is there any negative aspects of really low fasting gastrin? I havent found any online really.
Thanks guys.
