An immunological device of the present invention comprises: (1) a sample region for accommodating a test sample to be analyzed; (2) a conjugate region which is in engagement with the sample region and includes an anti-I-hCG antibody conjugated with a probe material-label and an anti-βcf hCG antibody conjugated with a probe material-label; (3) a signal detection region which is connected to the sample region, includes a first detection line having the anti-I-hCG antibody immobilized thereto, a second detection line having the anti-βcf hCG antibody immobilized thereto, and a control line, and is in engagement with the conjugate region; and (4) an absorption region located downstream of the signal detection region and absorbing the test sample that has completed a signal detection reaction. The device minimizes the false negative due to a high-concentration hCG-induced hook effect and/or an interference effect of hCG-βcf and as such, enables accurate pregnancy diagnosis.
