Networking

I would like to network with other RN's working in an Occupational Health Center (mine is hospital-based) who also completes NIDA and Non-Nida drug screens. We have had several questions recently regarding what defines "Abnormal color" a recent urine specimen was totally clear (absence of colo)r considered "abnormal" and not acceptable. What are ypur thoughts? I understand the definition of dilute specimen......this specimen was not blue, did not smell like bleach, did not foam.....was totally clear.
Thank you.
