PROBLEM TO BE SOLVED: To assay a specimen with a simple operation by separating serum and plasma from whole blood. SOLUTION: An enzyme immunoassay instrument 10 is configured such that a developing substrate 15 capable of fluid administration by a capillary phenomenon is provided with a specimen addition region 44, a marker reagent region 45, and a detection region 46 downstream thereof. An operating unit 20 capable of oscillating around a spindle 22 is provided in a position facing the upstream developing substrate 15. The operating unit 20 has a specimen dropping section 24 and a blood cell separation membrane 26 provided on one side of the spindle 22 to face the specimen addition region 44, the specimen dropping section 24 dropping the whole blood, the blood cell separation membrane 26 separating and removing blood cells from the whole blood, and has a storage tank 29 provided on the other side of the spindle 22, the storage tank 29 having a developing liquid 28 stored therein. Claws 16 and 17 are provided in a position facing the storage tank 29 to break a sealing membrane 30 of the storage tank 29 to let the developing liquid 28 flow out. By turning the operating unit 20 after the droppage of the specimen, the sealing membrane 30 of the storage tank 29 is broken by the claws so that the developing liquid is supplied to the developing substrate and a developing liquid pad 34, thereby the blood cell separation membrane 26 is set apart from the specimen addition region 44.
