The present disclosure relates to a fluid analyzing device that includes a sensing device for analyzing a fluid sample. The sensing device includes a microchip configured for sensing the fluid sample, and a closed micro-fluidic component for propagating the fluid sample to the microchip. The fluid sample can be provided to the micro-fluidic component via an inlet of the fluid analyzing device. And a vacuum compartment, which is air-tight connected to the sensing device, can create in the micro-fluidic component a suction force suitable for propagating the fluid sample through the micro-fluidic component.

This disclosure provides an integrated and automated sample-to-answer system that, starting from a sample comprising biological material, generates a genetic profile in less than two hours. In certain embodiments, the biological material is DNA and the genetic profile involves determining alleles at one or a plurality of loci (e.g., genetic loci) of a subject, for example, an STR (short tandem repeat) profile, for example as used in the CODIS system. The system can perform several operations, including (a) extraction and isolation of nucleic acid; (b) amplification of nucleotide sequences at selected loci (e.g., genetic loci); and (c) detection and analysis of amplification product. These operations can be carried out in a system that comprises several integrated modules, including an analyte preparation module; a detection and analysis module and a control module.

A method for determining a numerical score representative of a patient's health, is characterized by the following steps. At an initial calibration step, a database is established from a series of indicators relating to the state of health of the patient, each indicator being assigned a numerical value, and afterwards a statistical analysis of this database is performed so as to establish for each of said indicators a score depending on a measured value of the indicators of the state of health with respect to reference values, and to establish at least four groups constituted by said indicators, each of said groups representing information corresponding respectively to oxidative stress, hereinafter Group 1; to functions of the digestive brain, hereinafter Group 2; to functions of the reptilian brain, hereinafter Group 3; and to physical abilities of the patient coupled to his information on his general state of health, hereinafter Group 4. Furthermore, a value is assigned to each group, then a health score S specific to the patient is calculated using the formula:

S=(Value Group 1+(2* Value Group 2)+(2* Value Group 3)+(3* Value Group 4))/(2* Number of groups)

A testing module is provided. The testing module includes a carrier, a block member, and a sampling assembly. A flow path connects a storage chamber to a mixing chamber to guide the flow of a fluid. The block member is formed in the flow path to block the fluid from flowing from the storage chamber to the mixing chamber before the connection of the sampling assembly. When the sampling assembly which contains a test sample is connected to the carrier, the fluid mixes with the test sample and flows to the mixing chamber.

The collection kit 1 according to the present invention comprises a collection tool 10 for collecting saliva, a container body for housing the collection tool 10 and a preservation solution for saliva, and a cap for closing the container body. The collection tool 10 comprises a saliva absorbent 12 for collecting saliva, a housing body 14 for housing the saliva absorbent 12, and a pressing body 16 for pressing a collection body 12 and forming a suction space S that is for sucking the saliva and the preservation solution from the outside of the container body 22.

A target analysis tool and a target analysis method that allow easily analysis of a target. The first target analysis tool includes: a first chamber; a second chamber; and a third chamber. The first chamber, the second chamber, and the third chamber are disposed continuously in this order. The first chamber contains, as a first reagent, an immobilized first binding substance obtained by immobilizing, on a carrier, a first binding substance that binds to a target. The second chamber contains, as a second reagent, a labeled second binding substance obtained by binding a labeling substance to a second binding substance that binds to the first binding substance. The third chamber is a detection section in which the labeled second binding substance is detected.

Fluidic cartridge including a liquid container having a reservoir configured to hold a liquid. The liquid container includes an interior surface. The fluidic cartridge also includes a transfer tube that extends from the interior surface to a distal end. The distal end includes a fluidic port that is in flow communication with the reservoir through the transfer tube. The transfer tube has a piercing segment that includes the distal end. The fluidic cartridge also includes a movable seal that is engaged to the piercing segment of the transfer tube and configured to slide along the piercing segment from a closed position to a displaced position during a mating operation. The movable seal blocks flow of the liquid through the fluidic port when in the closed position. The piercing segment extends through the movable seal when in the displaced position.

A measurement cell (3) for measuring at least one constituent of a liquid sample, in particular blood, includes a reception space (9) for receiving the sample includes a measurement system (8) having at least one sensor electrode (10) exposed within the reception space; a first heat supply equipment (12) extending over a first area (91); a second heat supply equipment (14) extending over a second area (93), the first and second heat supply equipment being arranged to heat the sample within the reception space (9), wherein the second area (93) is larger than the first area (91).

Apparatus is provided for testing a biological fluid for presence of a biological particulate. The apparatus includes a tube, a plunger sized and shaped to be inserted into and advanced within the tube, and a filter. The apparatus is configured such that as the plunger is advanced within the tube while the biological fluid is within the tube, the biological fluid in the tube is pushed through the filter, thereby trapping, by the filter, the biological particulate present in the biological fluid. The apparatus is shaped so as to define at least one enclosed cavity containing a biological particulate-presence-testing-facilitation solution configured to test for the presence of the biological particulate trapped by the filter. The enclosed cavity is configured to open while the plunger is inside the tube, so as to release the biological particulate-presence-testing-facilitation solution within the tube. Other embodiments are also described.
