Sample workflow manager extensions for rack-based sample distribution

Analytical, pre-analytical, and post-analytical instruments communicate events via messages (ASTM or HL7). To support fully automatic laboratories, these messages have to be evaluated and answered in accordance with a laboratory configuration, so that samples can be distributed in a more targeted manner. Of crucial importance here is the complexity of the work processes being mapped (aliquoting, load balancing, fast processing, etc.). Depending on the nature of a preanalytic Instrument sample containers are distributed individually or together with other sample containers on a rack. In the latter case an optimal Distribution that considers all sample containers and resolves potential conflicts between those sample containers has to be determined.
