Ideas on improving rates of missed/delayed diagnoses in PCP type visits/Pernicious Anemia

Thank you for your interest. This is a worldwide problem, and the pernicious anemia/B-12 newsgroup now has over a thousand members with many people trying to work this out for themselves.
I can point you to many articles about numerous problems with B-12 testing. Shockingly, alternative tests (transcobalamin) that detect active B-12 have been available since the 1970s.
These links captures some of articles:
I can also point you to numerous articles by hematologists that pernicious anemia can present without overt anemia. A major befuddlement is caused when low iron that results from malabsorption keeps the blood cells appearing normal in size to the computers.
Neuropsychiatric disorders caused by cobalamin deficiency in the absence of anemia or macrocytosis.

I also have many articles that aren't fully accessible online. A great deal of former knowledge has been lost in today's medical education on this particular topic, and I would like to see it resurrected.
I previously proposed to the group that since pernicious anemia is an autoimmune disease with known overlap with thyroiditis and other autoimmunes, a deliberate search for it in patients without an additional lab diagnosis justifying their symptoms (apart from the treated Hashimotos, e.g.) would be helpful. As I mentioned, the CEO of Isobel ran my symptom history and identified B-12 deficiency as one of the options from symptoms that went back to my 20s. I was diagnosed at age 56 when I asked for the IF blocking antibody test which was positive, as were parietal cell antibodies and elevated MMA and homocysteine. I had seen a total of about 70 doctors. I continue to be mocked by the medical system as I try to attend to my gastroenterological and neurological difficulties. In spite of a bonafide diagnosis confirmed by multiple hematologists, most doctors simply can't get their head around pernicious anemia without anemia. You're right. It needs new language. Even when the patient identifies the problem (which is shockingly a common scenario according to Martyn Hooper, head of the Pernicious Anemia Society), most struggle to obtain adequate treatment even though this is the cheapest of deadly disorders to treat.
Please feel free to give me a call or email your needs for next steps. I am no means an expert on the problem having worked it out for myself just recently, but I also copy Martyn Hooper in the U.K. who has now written two books and founded a non-profit to help these people. There are additional lieutenants on our newsgroup that know a tremendous amount, one of who (Andrea MacArthur) diagnosed herself after a 13-year ordeal.

I think that a lot of what passes for diagnosis is BS. 5 hematologists at major institutions now confirm my pernicious anemia. But some clinicians can't get their head around it since I wasn't often overtly anemic. Members of a major clinic might have trouble admitting they were wrong. Easier to call the patient crazy and slap on DXes with no laboratory verification. Physicians SAY they are going to work with patients who do some of the diagnosis lifting somehow through the Internet. My experience is that this is the very rare physician.
