Abstract: An immune device for pregnancy diagnosis of the inventive concept includes a sample region for receiving a test sample to be analyzed; a conjugate region connected to the sample region and including an anti-I-hCG antibody conjugated with a probe and an anti-?cf hCG antibody conjugated with a probe; a signal detection region connected with the conjugate region, wherein the signal detection region includes a first test line having an anti-I-hCG antibody immobilized to the first test line, a second test line having an anti-?cf hCG antibody immobilized to the second test line, and a control line; and a wicking region located downstream of the signal detection region, wherein the wicking region absorbs the test sample for which a signal detection reaction has terminated.

Abstract: A one-step diagnostic device for simultaneously detecting and distinguishing between a normal pregnancy and an ectopic pregnancy and methods for preparing the device are disclosed. Utilizing the device and principles of the present invention, normal pregnancy and ectopic pregnancy can be rapidly and accurately determined at an early stage by immunologically detecting the morphological differences between human chorionic gonadotropin (hCG) and modified forms thereof, which are secreted into the body fluid of a pregnant female.
