Crow, I still don't see how you reach the conclusion that Valimed can't verify an admixture.
I understand that TPN ingredients are complex and formulated to meet each patients individual nutrition needs and it would be totally impractical to signature them even if it was possible.
I believe (regardless of the hype) that Valimed cannot distinguish between steril and non-sterile drugs.
What I don't understand is what would be the usefulness of Valimed if it can't verify a high risk admixture? Sure it would have some utility in verifying the selection and strength of each ingredient, but how about making sure that the admixture was compounded in the right proportions? I thought that was the most important concern, human error in mixing, not selecting the ingredients.
I propose that if Valimed can be used to discriminate between authentic and counterfeit drugs, then it can validate a admixture. Pharmaceuticals have all kinds of stuff in them besides the active ingredient(s).
What say ye.
