Abstract
A slide for use in microscopic examination of biological fluid is constituted by two plates of transparent material, one plate being a bottom and the other plate being a cover, the plates forming wells which are filled by capillarity with the biological fluid to be examined. A plurality of reliefs form a plurality of computation chambers in each well. The reliefs which define each computation chamber sectioned along a plane perpendicular to the bottom of the well have a shaped section along a profile assimilable to a polygon having at least one right angle.

A slide for use in microscopic examination of biological fluid for a computation of elements in a predefined sample, said slide comprising:
- a first plate and a second plate of transparent material, said first plate forming a floor and said second plate forming a covering, said plates forming there between at least one well with a bottom;
- and
- a computation chamber defined by a relief extending upwardly from said bottom of said well, said computation chamber having a floor;
- wherein:
- said relief has an internal lateral wall facing said computation chamber and extending from said floor to the upper extremity of said relief;
- and
- said floor of said computation chamber and said internal lateral wall of said computation chamber substantially define a right angle.
