Below is link to excellent source for all lab tests for PA/IDA, with exception of the new holocobalamin available in the UK. All tests are described in great detail, their description
of neuropathy symptoms is one of the best I have come across. I suggest that reviewing
this material patients can be better informed of what to ask next time they see their GP.
It even lists as symptom the inability to detect low blood sugar periods. I had those but did not know what they were until last week.
Best wishes in your endeavours to attain good health,
