Not sure if they can.I wonder if they're able to tell which type of insulin was the cause.
I'm no expert but there are long and short acting types, so it would be relevant.
I’d be interested to know if the TPN pharmacy solely made up TPN. If so, there would be absolutely no reason for insulin to be there.
I think it would have to be a very clean environment with sterile techniques used so I don’t see how general pharmacy stuff would happen there.
I don’t know though.
Another thing. Would the TPN bag then be hygieniclly sealed in another bag, more from a contamination point of view than anything else?
