getting active b12 test done

[shevie]

I am seriously thinking about sending away to get an active b12 test done, at St Thomes's Hospital. I had my last jag 8 weeks ago, am due my next on 3rd june but i guess it best not to have that done? How long should I leave it to be sure the test will be accurate?

I have read others on here say 6 months. Unfortunately I didn't find out about active B12 until after starting treatment. Now I wouldn't want to take that risk of stopping treatment. Others have had private tests done after stopping supplements for 2 months and discovered it was not enough.
