A thin fiim centrifuge device comprising: a sample inlet to inject a sample; a sample chamber to store the sample injected into the sample inlet; a specimen chamber to store a specimen obtained from the sample during centrifugation; a remnant chamber to store a remnant rather than specimens produced during centrifugation; a bottle neck channel to connect the specimen chamber to the remnant chamber directly; one or more assay sites in which a capture probe to be bound to the specimen is immobilized and/or reagent for biochemical reactions with the specimen is stored; a trash chamber to collect debris not bound to the capture probe by a washing process; a rotatable hydrophobic body in which the sample inlet, the sample chamber, the specimen chamber, the remnant chamber, the trash chamber, the bottle neck channel and the assay site are integrated; one or more fluid flow devices (41a, 41b) to transfer the specimen from the specimen chamber to the assay site upon non-rotation of the body, the fluid flow devices selected from the group consisting of a hydrophilic fluid flow pump, a chamber pump, an erythrocyte pump and an absorption pump; and a liquid valve coated with a super-hydrophilic material, to provide a passage to connect the specimen chamber to the assay sites, allowing the specimen retained in the specimen chamber during centrifugation to flow to the assay site by the fluid flow device upon non-rotation of the body, characterized in that as a fluid flow device an absorbent pad or a sample pad is provided between the terminal of the liquid valve and an inlet of the assay site, to transfer the specimen from the specimen chamber to the assay site, based on an absorption force to absorb the specimen reaching the terminal of the liquid valve. a sample inlet to inject a sample; a sample chamber to store the sample injected into the sample inlet; a specimen chamber to store a specimen obtained from the sample during centrifugation; a remnant chamber to store a remnant rather than specimens produced during centrifugation; a bottle neck channel to connect the specimen chamber to the remnant chamber directly; one or more assay sites in which a capture probe to be bound to the specimen is immobilized and/or reagent for biochemical reactions with the specimen is stored; a trash chamber to collect debris not bound to the capture probe by a washing process; a rotatable hydrophobic body in which the sample inlet, the sample chamber, the specimen chamber, the remnant chamber, the trash chamber, the bottle neck channel and the assay site are integrated; one or more fluid flow devices (41a, 41b) to transfer the specimen from the specimen chamber to the assay site upon non-rotation of the body, the fluid flow devices selected from the group consisting of a hydrophilic fluid flow pump, a chamber pump, an erythrocyte pump and an absorption pump; and a liquid valve coated with a super-hydrophilic material, to provide a passage to connect the specimen chamber to the assay sites, allowing the specimen retained in the specimen chamber during centrifugation to flow to the assay site by the fluid flow device upon non-rotation of the body, characterized in that as a fluid flow device an absorbent pad or a sample pad is provided between the terminal of the liquid valve and an inlet of the assay site, to transfer the specimen from the specimen chamber to the assay site, based on an absorption force to absorb the specimen reaching the terminal of the liquid valve.
