1. A multichambered container adapted to be rotated about a longitudinal axis through said container for determining the concentration of plasma constituents, comprising:

  • a plurality of chambers integrally formed in said container, each of said chambers defined by a plurality of walls, each of said chambers being non-communicable with each other and said chambers being accessible by a pipetter;

    a means for separating plasma from a whole blood sample positioned in a first chamber;

    a reagent positioned in a second chamber for reacting with a constituent of said plasma separated from said whole blood sample; and

    windows positioned in a chamber in said multichambered container for allowing optical monitoring of a reaction occurring in said chamber, whereby rotation about said longitudinal axis through said container causes separation of said plasma from said whole blood sample with said means for separating.
