One embodiment of the present invention provides a detection kit for detecting c-Met gene expression, wherein the detection kit includes a primer set which is specifically bound to the c-Met gene; and a cleavable probe which is specifically bound to the inside of a c-Met gene amplification product which is amplified by the primer set. Another embodiment of the present invention provides a method of measuring the c-Met gene expression by using the detection kit according to one embodiment of the present invention. The method according to one embodiment of the present invention is used to efficiently detect a low concentration of c-Met gene expression for cancer diagnosis and prognosis diagnosis.
