Doctors letter

So I called the practice this morning after leaving the letter in on Monday ... the GP I complained about is on holiday from last Friday to next Thursday so potentially another 2 weeks before I get a reply.

My question is, if I bite the bullet and send inject tonight, and they want blood tests in 2-3 weeks time, will the self injection affect the results ?

Thank you all!

I think the answer has to be "yes" JordanC unless of course any serum B12 test result taken in a fortnight comes out low

looking back at your posts it looks like you are on maintenance shots so the blood test isn't going to mean anything unless it comes back low - but past experience implies that it won't.

Do you know what blood tests they are doing in 2-3 weeks? is it serum B12 and folate or are they planning on doing other tests?


I've asked them to do the PA test, check ferritin and folate levels - doesn't mean they will but I have requested them. I've given them the evidence stating that high Serum b12 levels don't mean anything when you're getting the injections but she didn't listen to that when I was in with her. Worried incase they take even those off me!

Thank you


Check the pinned posts but IFA probably won't be affected if you supplement 2-3 weeks beforehand - and wouldn't affect folate or ferritin.


I can never see these pinned posts - I'm always on a mobile!


think they are right down at the bottom if you are using a mobile - to the right if you are using a browser
