Abstract: Methods and systems for determining the concentration of one or more analytes from a sample such as blood or plasma are described. The systems described herein can be configured to withdraw a sample from a source of fluid, direct a first portion of the withdrawn sample to an analyte monitoring system and return a second portion of the sample. The analyte monitoring system can be connected to the fluid source via a connector that is configured to improve fluid flow and reduce blood clotting risk. These goals can be accomplished, for example, by employing coatings in or on a connector, positioning a resilient substance at or near the junction, by reducing dead space volume, by using resiliency to improve fit, by extending a portion of one connector to better mate with a portion of another connector, etc.

Abstract: Methods for configuring a test setup that support reuse of previously defined sub-configuration parameter values without reference to individually-named sub-configuration files are provided. In these methods, each sub-configuration parameter value is automatically associated with a test case name within the test, and this association is represented in context data structures. During test configuration, for each set of sub-configuration parameter values, the user may reuse previously-defined values simply by specifying the name of the test associated with the previously-defined values. A system and a user interface for configuring a test setup are also described.
