An improved laboratory slide and related methods of manufacture and use, wherein the slide is designed for analysis and/or testing of liquid specimens and the like. The improved slide comprises a transparent upper coverslip affixed to a lower slide plate by a thin bonding agent of controlled thickness which may be a substantially monocellular thickness on the order of about 0.001 inch or less. In some forms, the bonding agent is shaped in cooperation with the slide plate and coverslip to define one or more examination chambers into which liquid specimens may be drawn by capillary action for viewing and analysis. In other forms, the bonding agent defines one or more elongated flow channels through which a specimen may be drawn, wherein the flow channels may be of varying height and/or include selected reagents along their lengths to perform selected testing of biological specimens and the like.
