Bhupinder This is an interesting idea...but it raises issues as you have to have normal ranges for each of these. I do not see why the results could not be duplicated in multiple units is required - at present we do not have the ability to add multiple values to a single element apart from as reference ranges.
What do others think? I think Labs will probably push back on this one.
