Description

TECHNICAL FIELD The present invention relates to an immune reaction analysis device, and more particularly to an immune reaction analysis device equipped with an incubation chamber. BACKGROUND ART With the development of technology in various related fields such as medicine and biotechnology, the tests for detecting various molecular indicators such as blood cells, genes, proteins, antigens, and pathogens in predetermined biological samples such as urine and blood have been widely performed. The inspection process is generally performed by taking a sample, reacting the collected sample with a predetermined reagent suitable for a desired indicator, and then analyzing and observing changes that occur. in this way, it is possible to perform qualitative and/or quantitative analysis on various molecular indicators included in the sample, and based on this, information on diagnosis, progression, prognosis, etc. of the disease can be obtained. The immune reaction based on specific binding between antigens/antibodies is widely used for such testing. Immune reaction technologies include a chromogenic method, a chemiluminescent method, a method using fluorescence, and the like, depending on the type of substrate used for the detection of an analyte. The immune reaction requires incubation for the reaction of reagents and samples. When using an analysis device without an incubation chamber, the user must perform incubation in a separate device. In this case, if a large number of tests are performed, it is so hard to control the incubation time for individual cartridges, that it is difficult to make an accurate diagnosis. In addition, since the user has to carry the incubated cartridge to the reading device, the user's workload increases.
