delta checking on lab results

The set up for delta checking of lab results is far from useful. there is a large need for this to be redesigned. It needs to be at a minimum set at each analyte and the time factor needs to be in hours instead of months. The current setting makes staff ignore the delta check alerts because of the time span used and it needs to be specific to the analyte tested and programable in either percentage or absolute value or a combination of the both so that at low values, the unnecessary flag does not occur.
