Can I ask how quickly vitamin levels can change. I had good results for B12 and folate 3 years ago, and doctor is saying it doesn’t need repeating.
I have had 3 blood tests in the last 4 months and results all less than 5 but over upper limit of 4.4. So doctor has finally put me on 25mg Eltroxin.
GP has given me a 3 month prescription, but I intend going back at 6 weeks to get repeat blood test done, I need to know what might convince them to test vitD and repeat VitB12 etc too.
