CHAPTER 8
User Defined Reagents
Overview
The user may define up to 100 chemistries on the UniCel DxC 600/800 using an endpoint or rate, and
calibrated or non-calibrated methodology. A set of parameters must be defined which fully
characterizes an analyte. When the parameters are defined, they are stored in memory according
to the test name designated in System Setup. Chemistries can then be configured on the test
selection menu for programming along with the Beckman Coulter-defined chemistries. When
configured, quality control, reference ranges, and special calculations may be used with these
configured chemistries.
In addition, up to 10 of the 100 user defined chemistries may be configured with the Expanded User
Defined Chemistry feature. Refer to the end of this chapter for further information.
NOTE
The sample type for UDR must be serum, plasma, CSF or urine. Do not use any other sample type.
