ABSTRACT:
A method for reading slides bearing fluorescent deposits, such as used in serology or molecular biology analysis, includes: incubating a slide with a sample of serum from a patient, or a dilution thereof, and revealing antibodies in the sample bound to the deposits by labelled reagents. Label reading and analysis is performed by a device including a slide positioner, light emitting diodes arranged in illumination channels to provide oblique illumination at different wave lengths, and a collection optic for forming an image of the deposits on a sensor.
