To provide a gene diagnosing and analyzing device which provides various examinations and facilitates a re-examination and is inexpensive and very safe, and a gene diagnosis support system.

The gene diagnosing and analyzing device which detects development or an array of genes from blood, body wastes, or a sample of an affected part with a chip for detection is equipped with a sample preprocessing and array or development detecting means and an analyzing device which obtains a disease and information regarding the disease by analyzing the detection result by referring to a diagnostic protocol and is constituted so that it carries out gene detection and analysis continuously; and a contents server which represents the correlation between a profile of the development, array, etc., of genes and the degree of progress of the disease, medicine sensibility, etc., and has a reference diagnostic protocol in a database is connected onto a network and analytic data of an examination result are sent to the server to read a corresponding diagnostic protocol, thereby being made able to perform diagnosis.
