Provided is a method of providing a self-improvement genetic testing service using artificial intelligence-based genome big data, the method comprising the steps of: receiving, from a subject’s terminal, the subject's group information including nationality, ethnicity, and race, and a genetic testing request event; extracting control group genotype information of a previously-stored control group that corresponds to the nationality, ethnicity, and race; for a pre-set disease and physical characteristics, comparing the subject's genotype information produced from a DNA sample extracted from the subject and the control group genotype information of the control group, with reference to a pre-set genetic marker; and if the control group genotype information is present in the subject's genotype information with respect to the pre-set genetic marker, determining the pre-set disease and physical characteristics to be present, generating a report, and transmitting same to the subject's terminal.
