An automated immunoassay apparatus is disclosed comprising a single optical reading device (2a, 2b) for reading two microtitre plates (9, 14). A first microtitre plate (9) is loaded into an upper plate holder (8) which is linearly translated at a fixed height. A second microtitre plate (14) is loaded into a lower plate holder (13). The lower plate holder (13) runs along a contoured track which varies the vertical height of the second microtitre plate (14).

1. An automated immunoassay apparatus comprising: a first mechanism for moving a first microtitre plate holder adapted to carry a first microtitre plate;a second mechanism for moving a second microtitre plate holder having one or more guide wheels attached thereto and being adapted to carry a second microtitre plate, wherein said second mechanism comprises one or more linear guide tracks or rails and one or more sliding devices which are configured to translate along said one or more linear guide tracks or rails in a first direction;one or more pivoting arms connecting said one or more sliding devices to said second microtitre plate holder;a single reading device configured to read first and second microtitre plates carried by the first and second microtitre plate holders respectively; anda contoured track, said one or more guide wheels being arranged to follow said contoured track in a second direction;wherein one of the first or second directions functions to raise and lower the second microtitre plate holder in height. 2. The automated immunoassay apparatus as claimed in claim 1, wherein said first mechanism comprises a drive mechanism for selectively translating said first microtitre plate holder forwards or backwards along a longitudinal axis, wherein said first mechanism is configured to maintain said first microtitre plate holder at substantially a constant height along at least 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% or 100% of the length of said longitudinal axis. 3. The automated immunoassay apparatus as claimed in claim 1, wherein said first mechanism comprises one or more linear guide tracks or rails and one or more sliding devices which are configured to translate along said one or more linear guide tracks or rails. 4. The automated immunoassay apparatus as claimed in claim 3, further comprising a first microtitre plate positioned on said first microtitre plate holder. 5. The automated immunoassay apparatus as claimed in claim 1, wherein said second mechanism comprises a drive mechanism for selectively translating said second microtitre plate holder forwards or backwards along a longitudinal axis, wherein said second mechanism is arranged and adapted to vary the height of said second microtitre plate holder along at least 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% or 100% of a length of said longitudinal axis. 6. The automated immunoassay apparatus as claimed in claim 1, further comprising a drive motor for translating said one or more sliding devices and said second microtitre plate holder. 7. The automated immunoassay apparatus as claimed in claim 1, wherein said one or more pivoting arms comprise four pivoting arms which form a parallelogram with said second microtitre plate holder and said one or more sliding devices. 8. The automated immunoassay apparatus as claimed in claim 1, wherein said one or more pivoting arms are configured to ensure that said second microtitre plate holder remains substantially horizontal during translation. 9. The automated immunoassay apparatus as claimed in claim 1, wherein said contoured track in combination with said one or more guide wheels is arranged to cause said second microtitre plate holder to be raised and lowered in height and wherein said contoured track has a substantially horizontal region, a first ramp portion connected to a first side of said substantially horizontal region and a second ramp portion connected to a second side of said substantially horizontal region. 10. A method of reading microtitre plates comprising: using a first mechanism to translate a first microtitre plate holder relative to a single reading device, the first microtitre plate holder carrying a first microtitre plate;using a second mechanism to translate a second microtitre plate holder relative to said single reading device, wherein said second mechanism comprises one or more linear guide tracks or rails and one or more sliding devices which are configured to translate along said one or more linear guide tracks or rails, and wherein one or more pivoting arms connect said one or more sliding devices to said second microtitre plate holder;positioning a second microtitre plate on said second microtitre plate holder;directing one or more guide wheels attached to said second microtitre plate holder to follow a contoured track to cause said second microtitre plate holder to be raised and lowered in height; andreading said first microtitre plate and said second microtitre plate using said single reading device. 11. An assay apparatus comprising: one or more first sliding devices for sliding along one or more linear guide tracks or rails, said one or more first sliding devices being attached to a first microtitre plate holder; andone or more second sliding devices for sliding along one or more linear guide tracks or rails, said one or more second sliding devices being connected to a second microtitre plate holder via one or more pivoting arms, wherein a height of said second microtitre plate holder may be varied during sliding of the one or more second sliding devices;wherein second microtitre plate holder comprises one or more guide wheels for engaging with one or more guides, wherein said one or more guides have a vertical profile which varies along an axial length of said one or more guides and wherein when said one or more guide wheels engage with said one or more guides, a vertical height of said second microtitre plate is caused to vary. 12. The assay apparatus as claimed in claim 11, wherein said first microtitre plate holder and said second microtitre plate holder are arranged to pass by a common reading device, said reading device being arranged to measure an optical density of samples in a first microtitre plate loaded on said first microtitre plate holder and a second microtitre plate loaded on said second microtitre plate holder.
