Abstract: An assay device for testing of liquid samples for drugs of abuse has a transparent container for retaining a liquid sample. A backing member is within the container and is curved so that its front surface corresponds to the curvature of the container wall. Immunoassay test strips are on the front face of the backing and are visible through the container wall. Each test strip is enclosed in a transparent pocket which has a bottom opening through which the bottom portion of the test strip protrudes to contact the liquid sample within the container. The liquid then flows upwardly through the test strip to react with reagents within the test strip.

Abstract: An apparatus and method of automated blood cell analysis uses technologies from other systems to create a new, robust, improved type of automated microscope, which uses electronic motors and a closed loop control system to minimize ambient factors, such as jarring and temperature changes. Pre-stained blood smear slides are first coated with a thin film of oil and are loaded into a carousel from which they can individually be analyzed. The slides are moved under a low magnification microscope; an optimal area of examination is determined; a focal plane map is calculated for that area, and the positions of white blood cell candidates are computed. The slide is then moved under a high power microscope where a refined focal plane map is computed and the individual white blood cell candidates are imaged. The cells are preclassified and the images are made available for analysis by the technician.
