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

Any good references on the need / lack of need for this?
