This may have the info yu require.

I'm not certain what hard evidence there is, but as good practice the UK
NEQAS for Vitamin Assays will be using the same precautions as the UK
NEQAS for Paediatric Bilirubin in preparing future specimens, ie lights
off and amber tubes
Best wishes
David

Do labs insist on samples for vitamins A & E being protected from the
light?
Any good references on the need / lack of need for this?
