When to test?

[edeuweed]

Good morning.....I have PA diagnosed in 2016. My younger daughter has Sapho Syndrome (autoimmune) and has also suffered Endometriosis (?autoimmune) for nearly 30 years....She is about to have an endoscopy, also several bi opsies. I keep feeling that a lot of her symptoms could be PA...I have eventually convinced her via her watching the Sally Pacholock film (good and bad).....to investigate. So my question is....she has been taking a Biocare B complex for about 5 years obviously this must be effecting her blood results.....how long would she need to stop the pills before she would get an accurate B12 reading??? I thank you for any help.

I would recommend a few weeks / a month to 6 weeks.

If taking biotin stop 2 days before test.

Fast 6 to 8 hrs before test.

Hope this helps.
