A detection device (1) and detection method for detecting a pre-disease state. The device (1) comprises a sample acquisition unit (10), wherein the sample acquisition unit (10) acquires comparison sample data and single sample data of a detection object; a DNB setting unit (11), wherein the DNB setting unit (11) sets DNB members; index calculation units (13, 14, 15, 16), wherein the index calculation units (13, 14, 15, 16) obtain composite indexes by calculating the distance between the probability distribution of the comparison sample data and the single sample data; and a state judgement unit (12), wherein the state judgement unit (12) judges that the detection object is in a pre-disease state when the composite indexes exceed a threshold value. Therefore, the DNB theory is effectively applied to single sample conditions, so that the pre-disease state can be simply and accurately detected. |
