Methods of using a disposable reagent pack with an analytical instrument to analyze a blood sample are provided. According to one embodiment, a disposable reagent pack comprising a sample well, a lysing solution well, and a red blood cell analytic sample well is used. A blood sample is placed into the sample well and the red blood cell analytic sample well. Fluid is selectively transferred between the sample well and the lysing solution well. Both the lysing solution well and the red blood cell analytic sample well are simultaneously presented to the analytical instrument for analysis.

Method of using a disposable reagent pack

A method of making a count probe comprises the following steps. A member is made having a conduit and an opening. A wafer is made including an aperture. The wafer is removably inserted into the opening such that the wafer is removably retained within the opening by an interference fit between the wafer and the member.

Method of making count probe with removable count wafer

A particle count probe comprises a wafer having an aperture. A first member is provided having a fluid passageway. A second member is removably mounted to the first member, and cooperates with the first member and the wafer to position the wafer so that the aperture of the wafer aligns with the fluid passageway.

Mechanical capture of count wafer for particle analysis

The present invention relates to methods and materials for the detection of ketone and aldehyde analytes in fluid samples by means of reacting analyte containing samples with a first solid matrix material to which a nitroprusside salt is coupled and a second solid matrix material to which an amine is covalently coupled. Methods and devices are also provided for ascertaining the fat catabolism effects of a weight loss dietary regimen comprising determining the breath acetone concentration of the subject.

Method and device for ketone measurement

An improved additive transfer device for storing and subsequently transferring a fluid material from an additive container to a rigid or semirigid solution container having an exposed closure. The improved additive transfer device is mounted on the additive container and includes a closure assembly fabricated from three components; a pierceable stopper, a slidable piercing pin and a hood member. The closure assembly is adapted to be positioned on the solution container. The two ended slidable piercing pin is disposed in a central opening in the pierceable stopper so that one end will pierce a diaphragm contained in the pierceable stopper. Resistance elements are provided between the slidable piercing pin and the central opening in the pierceable stopper to hold the slidable piercing pin away from the diaphragm in the pierceable stopper in one position and allow the slidable piercing pin to pierce the diaphragm and retain it within the central opening in a second position.

Additive transfer device

A pressurized additive transfer device for storing and transferring of a fluid material to a solution container such as a rigid container or an I.V. bag having an exposed pierceable closure or port. The transfer device is self-pressurized and includes a closure with channel portions to permit the introduction of a pressurizing media. The closure also has a central opening in alignment with a pierceable diaphragm. A piercing member having a double pointed end is disposed in the central opening which affords a movement of the piercing member toward the pierceable diaphragm to pierce it. Frictional engagement elements are provided between the piercing member and the central opening to hold the piercing member when it punctures the diaphragm as well as the solution container closure or port. In one embodiment, a vent slot is provided in the piercing member to serve as a vent for the solution container.
