Patent ID: 8241572

Claim:
An apparatus for analyzing biologic fluid, comprising: a first planar member; a second planar member, wherein at least one of the first planar member and second planar member is transparent; and at least three separators disposed between the planar members, each separator individually having a height and the separators collectively having a mean height, separating the planar members to form a chamber having a height extending between the planar members; wherein the separators are independent of the first planar member and second planar member, and are randomly distributed within the chamber; and wherein at least one of the first planar member, second planar member, or separators is sufficiently deformable when the first planar member and second planar member are drawn toward each other by capillary force from a biologic fluid quiescently residing within the chamber to cause the mean chamber height to be substantially equal to the mean height of the separators.
