    Abstract: The invention provides a microfluidic system comprising a cartridge coupled to a motor and adapted to move a fluid sample to a plurality of locations on the cartridge. The cartridge is configured to rotate on an inclined plane, thus providing for a combination of centrifugal force and gravitational force to move the fluid sample within the cartridge. Such a configuration may facilitate the performance of a sequential assay by making it easier to move a fluid radially inwards within the cartridge. The cartridge provided comprises a reaction chamber (15) with at least three zones within the chamber: a first zone (Zone A) is positioned radially outward comprises a cuvette (45) for optical measurement; a second and third zones (Zones B and C) are positioned closer to a centre of rotation (25) and may comprise dried reagents spots (R1, R2).
