Patent ID: 7812952

Claim:
A method of serological analysis, comprising (a) incubating a serology slide comprising a reactive zone comprising a series of deposits of biological agents, with a sample of serum from a patient, or a dilution thereof, then (b) revealing antibodies in the sample bound to the deposits by labelled reagents, wherein label reading and analysis are carried out by a device comprising a means for positioning the slide, a means for illuminating the reactive zone and a collection optic, wherein: the means for illuminating the reactive zone comprises light emitting diodes arranged in illumination channels so as to enable an oblique illumination relative to an optical axis along which fluorescent light emitted by the microdeposits is captured by the collection optic; the device comprises at least two channels of diodes each emitting a specific excitation light; and the collection optic contains an objective forming an image of the deposits on a sensor.
