Abstract: A sample handling system includes a loading rack for receiving carriers with a plurality of test tubes holding samples. A robotic device transports a carrier with the samples to a positioner that moves the tubes within the carrier into an aspiration position. After aspiration, the robotic device returns the carrier to the loading rack. The system provides for handling of stat samples and automatic retesting of samples.

Abstract: The embodiments disclosed relate to determination of an item of interest in a sample. One embodiment relates to a structure which comprises a process path. The process path comprises a process lane including a process step performance lane where a process step is performed, and a process step avoidance lane where the process step is avoided. A first prime mover is operatively connected with the process path for moving a container holding the sample along the process path. A first pipetting system is operatively associated with the process path for introducing the sample to the container. A second pipetting system is operatively associated with the process path for introducing a reagent to the container. A device is operatively connected with the process path and is selectively engagable with the container for mixing the sample and the reagent in the container.

Abstract: The embodiments disclosed relate to determination of an item of interest in a sample. In one method, a process path comprising a process lane including a process step performance lane where a process step is performed, and a process step avoidance lane where the process step is avoided is provided. A container holding the sample is moved along the process path. The sample is introduced to the container. A reagent is introduced to the container. The sample and the reagent are mixed in the container. The container is selectively positioned in a selected one of the process step performance lane and the process step avoidance lane. The item of interest in the sample is determined based upon a reaction between the sample and the reagent.

Abstract: Embodiments described herein provide methods of performing a process for determining an item of interest in a sample. In one embodiment, a container for holding the sample is accepted in a process lane where a process step is selectively automatically performed on the sample in the container. The process step is selectively automatically performed on the sample in the container. An effective length of the process lane is maintained constant while a physical length of the process lane is selectively varied.

Abstract: The disclosure relates to a gripper arm for use in conjunction with a robotic arm for gripping a tool wherein the tool is retained in the gripper arm until a positive action signal and lack of pressure from the tool are simultaneously provided. The tool cannot be discharged from the gripper arm under other conditions including power loss to the robotic device.
