A device for fluid assay comprising a carousel (12), mounted about a hub (14), disposed in a complementary shaped housing (16). The carousel (12) is divided into a plurality of chambers (20, 22, 24, 26, 28, 30) disposed radially about the hub (14). The chambers (20, 22, 24, 26, 28, 30) are arranged
A device for fluid assay comprising a carousel (12), mounted about a hub (14), disposed in a complementary shaped housing (16). The carousel (12) is divided into a plurality of chambers (20, 22, 24, 26, 28, 30) disposed radially about the hub (14). The chambers (20, 22, 24, 26, 28, 30) are arranged into pairs which are disposed diametrically opposite one another and which communicate with each other via the hub (14).

The invention claimed is: 1. A device for fluid assay comprising a carousel mounted on a hub comprising an assay component separation zone having a transverse channel formed therethrough and dividing the hub into two compartments, the carousel being rotatable about the hub to provide multiple configurations of the device, the carousel having a plurality of chambers being non-communicating across the assay separation zone in a first configuration of the device, a first chamber in fluid communication through the transverse channel of the separation zone with at least one other chamber in a second configuration of the device, and wherein a second chamber is in fluid communication through the transverse channel of the separation zone with at least one other chamber in a third configuration. 2. A device as claimed in claim 1, wherein a third chamber is in fluid communication through the transverse channel of the separation zone with at least one other chamber in a fourth configuration of the device. 3. A device as claimed in claim 1 wherein the device includes projections to engage with drive means of an automated fluid assay apparatus. 4. A device as claimed in claim 1 wherein the fluid is a body fluid which includes blood, blood components and urine. 5. A device as claimed in claim 1 wherein the separation zone is a chromatographic separation zone. 6. A device as claimed in claim 5, wherein the transverse channel is at least partially blocked by a filter material or binding retaining material effective for chromatographic separation. 7. A device as claimed in claim 6, wherein the filter means or binding retaining means is a frit. 8. A device as claimed in claim 1 wherein the chambers are disposed radially about the hub. 9. A device as claimed in claim 8, wherein said communicating chambers are disposed diametrically opposite one another about the hub. 10. A device as claimed in claim 1 further comprising an openable port disposed in the first chamber. 11. A device as claimed in claim 1 wherein at least one chamber is or comprises an optical material effective for allowing the passage of light therethrough. 12. A device as claimed in claim 1 wherein the carousel and hub are manufactured from different materials. 13. A device as claimed in claim 1 wherein at least one chamber comprises at least one aperture releasably and resealably sealed. 14. A device as claimed in claim 13, further comprising means for breaking said seal. 15. An apparatus as claimed in claim 13 further comprising means for assaying the assay component of the fluid. 16. A device as claimed in claim 1 wherein the channel is slanted with respect to the longitudinal axis of the hub so that flow of fluid through the separation zone in the second and third configurations is facilitated by gravity. 17. A method for fluid assay comprising the steps of: (a) contacting, in the device of claim 1, a body fluid to be assayed in the first chamber with assaying reagent in the first configuration; (b) rotating the carousel to the second configuration; (c) collecting a component to be assayed in at least one other chamber; and (d) assaying the component.
