ABSTRACT:
A transparent microscope slide for the diagnostic analysis of liquid specimens, the slide having on one surface a plurality of specimen retaining areas defined by a first boundary forming a test well and a second boundary forming a channel outside the first boundary. The channel, or confirming well, acts as a moat by retaining specimen liquid overflowing from the test well, yet does not interfere with microscopic analysis. The well can have a circular or square configuration, and the channel can have a square or circular ring configuration and be concentric with the well. The size of the wells can vary depending upon the particular liquid specimen analyzed and the diagnostic procedure utilized without interfering with the efficacy of the confirming wells.
