Abstract
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.
