After being diagnosed this time last year, loading doses done and now on three monthly injections. I had an MMA test in November around 5-6 weeks after a injection. At the time it didn't cross my mind that the jab could affect the outcome (I had stopped all extra supplementation). The thing is I'm due to see the haematologist on the 4th Jan for the results. I still haven't supplemented since my last jab in September so I'm feeling pretty rough. All initial symptoms have returned as up until Sept I was taking 2000ug B12 a day to top up. My three monthly injection is due now but I don't know whether to put it off until after I've seen the haematologist in the remote chance that the MMA test could be repeated. Any advice would be most welcome! I'm not sure of the cost of the MMA test on the NHS so unsure if the haematologist would sanction a repeat test.
