Drug screens

Good morning!!

I would like to network with other RN's who are certified in performing NIDA and Non-Nida drug screens. We are a hospital-based occupational health and recently had a question on what defines "abnormal color". A recent urine specimen was totally clear (absence of color). I understand the definition of a dilute specimen. It was also not blue, frothy or foamy or smelled like bleach, etc. which is considered abnormal. So if it is totally clear and within the temperature guidelines, you are accepeting this specimen? Someone asked why we dont accept "clear" as an abnormal color, or lack of what normal urine looks like. guidelines are specific on dilute specimens.

Thank you.
