First of all, a huge thank you to the wise people who have given so much information to me about PA. Thanks to you and a humble enough doctor who admitted she didn't know the NICE guidelines I am now on every other day loading doses and about to have the recommended re-blood test x10 days into my treatment. Can someone tell me what should be tested at this stage? I know my B12 should be sky high, but what else will they be looking for? My B12 was deficient 128 (180-999) and my MCV was high 97.5 (78-97) and my lymphocyte 0.8 (1.10-4) and monocyte count 0.1 (0.2-1.1) were low. Other than these anomalies my other results were well into normal.
