An automatic analyzing apparatus according to an embodiment includes first and second conveyance paths, a sample dispensing mechanism, and processing circuitry. The first conveyance path conveys a first container rack that holds a container housing the sample. The second conveyance path conveys a second container rack that holds a container housing at least one of a detergent solution for cleaning a probe that dispenses the sample, a diluent for diluting the sample, a buffer solution for mixing the sample, a solution used for a blank test with the sample, and a solution for performing calibration measurement for the apparatus. The sample dispensing mechanism is configured so that the probe can aspirate a liquid in the container of the first container rack and the second container rack. The processing circuitry controls operations of the first conveyance path, the second conveyance path, and the sample dispensing mechanism.

An object of the present invention is to provide a blood analysis method and a blood test kit, which are for performing quantitative analysis of components by precisely obtaining a dilution factor. According to the present invention, provided is a blood analysis method including a step of diluting a collected blood sample with a diluent solution; a step of determining a dilution factor by using a normal value of a normal component which is homeostatically present in blood; and a step of analyzing a concentration of a target component in the blood sample, in which the blood analysis method uses a member selected from the group consisting of a first storing instrument for storing a diluent solution, a separation instrument for separating and recovering blood plasma from the blood sample diluted with the diluent solution, a holding instrument for holding the separation instrument, a second storing instrument for storing the recovered blood plasma, and a sealing instrument for keeping the stored blood plasma within the second storing instrument, in which the diluent solution defines an amount of the normal component which is derived from the diluent solution and/or the members and may be contained in the diluent solution, and in which a volume of the blood sample is 50 μL or less, and a dilution factor of a blood plasma component in the blood sample is 14 times or more.

A system and method for automated single cell capture and processing is described, where the system includes a deck supporting and positioning a set of sample processing elements; a gantry for actuating tools for interactions with the set of sample processing elements supported by the deck; and a base supporting various processing subsystems and a control subsystems in communication with the processing subsystems. The system can automatically execute workflows associated with single cell processing, including mRNA capture, cDNA synthesis, protein-associated assays, and library preparation, for next generation sequencing.
