An apparatus includes a housing, a flow control mechanism, and an actuator. At least a portion of the flow control mechanism is movably disposed within the housing. The apparatus further includes an inlet port and an outlet port, and defines a fluid reservoir. The outlet port is fluidically coupled to a second fluid reservoir and is fluidically isolated from the first fluid reservoir. The actuator is configured to move the flow control mechanism between a first configuration, in which the inlet port is placed in fluid communication with the fluid reservoir such that the fluid reservoir receives a first flow of bodily-fluid, and a second configuration, in which the inlet port is placed in fluid communication with the outlet port.

A collection system configured to maintain the integrity of a bodily fluid sample has a proximal end portion, a distal end portion, and an inner surface defining a fluid flow path therethrough. The distal end portion is configured to be placed in fluid communication with a patient. The proximal end portion is configured to be placed in fluid communication with a fluid reservoir. The fluid flow path defined by the inner surface is associated with at least one flow characteristic configured to limit a stress within the flow of the bodily fluid between the distal end portion and the proximal end portion.

An object of the present invention is to provide a blood test kit of which a component in a small volume of blood can be mailed in a safe state by controlling the influence of the outside temperature during the mailing, and a highly accurate blood analysis method in which coefficient of variation of a measurement value is reduced. According to the present invention, a blood test kit including a diluent solution for diluting a blood sample; a separating means for recovering blood plasma components from the diluted blood sample; a container for storing the blood plasma components recovered from the diluted blood sample; and a cold insulation means for cold-insulating the container, is provided.

An object of the present invention is to provide a blood analysis method in which a high level of repeatability and reproducibility is achieved with respect to measurement values in a blood sample, and a blood test kit which is used for the blood analysis method. According to the present invention, a blood analysis method including a step of diluting a collected blood sample with a diluent solution; a step of quantitatively determining sodium ions in the diluent solution of the blood sample by using a solution containing -galactosidase and at least one substrate which is convertible by -galactosidase so as to determine a dilution factor from a normal value of serum and blood plasm sodium ions which are homeostatically present in the blood and the quantitative value of sodium ions; and a step of analyzing a concentration of a target component to be measured in the blood sample from the determined dilution factor and a measurement value of a concentration of the target component to be measured in the blood sample, in which the diluent solution is a diluent solution which does not contain sodium ions, is provided.

Provided relates to a continuous blood glucose measurement device which is produced with an assembled body attachment unit inside an applicator so as to minimize a user's additional work of attaching the body attachment unit to the body, thereby enabling the body attachment unit to be attached to the body by simply activating the applicator, and which is provided with a wireless communication chip in a body attachment unit so as to enable communication with an external terminal, thereby enabling simple and convenient use, without additional work of connecting a separate transmitter, and easier maintenance; and is activated by the user after the body attachment unit is attached to the body so as to enable the operation start time to be adjusted to an appropriate time according to user's needs, and to enable the operation to start in a stabilized state so that blood glucose can be measured more accurately.
