A container assembly is disclosed including an outer container, a hollow inner member, and a closure. The outer container has a closed bottom, an open top, and a sidewall extending therebetween. The hollow inner member is disposed within the outer container and has an inner surface defining at least one capillary channel. The inner member includes a first end adjacent to the open top of the outer container and has an outer periphery seated against the sidewall of the outer container. The closure has a proximal end and a distal end. The closure proximal end is seated at least partially within the first end of the inner member to seal the outer container and inner member and define a fluid collection chamber. The closure distal end defines a recessed area shaped to direct fluid under capillary action to the at least one capillary channel in the inner member.

Capillary action collection device and container assembly

A collection device and a method for collecting a biological sample, particularly whole blood, includes a separating member to separate the whole blood into its components, and at least reagent positioned to selectively interact with a component of the separated sample. The reagent is able to selectively interact with the plasma/serum, and is prevented from contacting or interacting with the whole blood.

Device and methods for collection of biological fluid sample and treatment of selected components

A collection container and a method for collecting a biological sample, particularly whole blood, includes at least one stabilizing agent in an amount effective to stabilize and inhibit protein degradation and/or fragmentation. The stabilizing agent is able to stabilize proteases in the biological sample, particularly at the point of collection, by inhibiting protein degradation and/or fragmentation in the sample when the sample is stored. The stabilizing agent includes one or more protease inhibitors.

Protease inhibitor sample collection system

A collection container and a method for collecting a biological sample, particularly whole blood, that includes at least one stabilizing agent in an amount effective to stabilize and inhibit protein degradation and/or fragmentation. The stabilizing agent is able to stabilize proteases in the biological sample, particularly at the point of collection, by inhibiting protein degradation and/or fragmentation in the sample when the sample is stored. The stabilizing agent includes one or more protease inhibitors.

The present invention is an additive preparation which contains an additive, an organic acid, a metal carbonate compound, and a surfactant agent which is capable of rendering the surface of a collection device to have properties that cause the surface to repel the adsorption of components of a body fluid sample. The preparation effervesces when in contact with a body fluid sample, thereby efficiently dispersing the additive and surfactant in a body fluid sample.

Additive preparation and method of use thereof

The present invention is an additive preparation for use in bodily fluid collection devices. The additive preparation has an additive, an organic acid and a metal carbonate compound. The preparation effervesces when in contact with a body fluid sample, thereby efficiently dispersing in a body fluid sample. The formulation is desirably tabulated to provide an effective, easily stored, and handled preparation. However, a binding or bulking agent may be added to the additive preparation formulation to provide binding and lubricating properties to the formulation. A binding agent enables granulating of the formulation without the forming of a pellet.

A blood collection device comprising formed additive particles. The additive particles are an improvement over available additive formulations that are powder blended in that the components of the additive particles of the present invention are in each formed particle. The formed additive particles comprise a fluoride salt and an ethylenediaminetetraacetate salt or a heparin salt to consistently minimize glycolysis and coagulation of a blood specimen with low hemolysis.
