1. An apparatus for analyzing biologic fluid, comprising:
- a tape including a first planar member and a second planar member spaced apart from one another and bonded together at discrete points, wherein at least one of the first planar member and second planar member is transparent, and a plurality of chambers, each having a height, are formed between the planar members, and at least three separators are disposed in each of the chambers, and wherein at least one of the first planar member, second planar member, or separators is configured to be sufficiently flexible such that when the first planar member and second planar member are drawn toward one another by capillary force applied thereto by a biologic fluid residing within the respective chamber, the at least one of the first planar member, second planar member, or separators deforms to produce a chamber having a substantially uniform chamber height;
a source reel on which the tape may be wound; and
a take-up reel on which the tape may be wound.

Abstract
An apparatus for analyzing biologic fluid is provided that includes a first planar member, a second planar member, and at least three separators. At least one of planar members is transparent. The separators are disposed between the members, and separate the members to form a chamber having a height. At least one of the members or separators is sufficiently flexible to permit the chamber height to approximate the mean size of the separators. During use, the biologic fluid to be analyzed is disposed within the chamber.

8. An apparatus for analyzing biologic fluid, comprising:
-
a tape including a first planar member and a second planar member spaced apart from one another and bonded together at discrete points, wherein at least one of the first planar member and second planar member is transparent, and a plurality of chambers, each having a height, are formed between the planar members, and at least three separators are disposed in each of the chambers; wherein each separator individually has a height and the separators collectively having a mean height; and wherein the separators are independent of the first planar member and second planar member, and are randomly distributed within each chamber; and wherein at least one of the first planar member, second planar member, or separators is configured to be sufficiently flexible such that 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, the at least one of the first planar member, second planar member, or separators deforms to cause a mean chamber height to be substantially equal to the mean height of the separators; and a source reel on which the tape may be wound; and a take-up reel on which the tape may be wound.
