I have a really quick question which I wondered if someone could help me with?
I had the first 6 injections 3 months ago and I am due my next one. I went to the doctors this week as I feel more tired and down than I did when I started. She says I am depressed but I honestly think its more than that. So before my injection next Thursday I considered paying for an Active B12 test. My question is - is there any point in doing this? Will I get an accurate answer or will the previous injections affect the level? I don't really understand what Active B12 actually means.
