Description

Hello, everyone. I am using MIMIC Ⅳ 2.0 database query urine ketone body found itemid '51484' is in the hematology test mode, the measurement of the specific value, I would like to ask this can be converted to common “negative”, “+”, “++”, “+++”, “+++”? ”, “++”, “+++”? Thanks for the time and resources you've spent on this!

You would have to define those values, e.g. you could define + as 5-15 mg/dL, ++ as 15-40, etc.
