Patent ID: 7491497

Claim:
A test card inside which sequential reactions and fluid transfer operations are performed under the effect of control means integrated into the card, said card comprising: at least two sequential reaction lines arranged in parallel, each reaction line comprising at least two fluid transfer systems arranged in series, at least two valves per parallel reaction line, the valves making it possible to control fluid transfers in series within a channel from an initial level (A, B or C) to a subsequent level (B, C or D), each level corresponding to at least one processing, each valve being made up of at least a means which can be deformed by an actuator for directly or indirectly closing of said channel, wherein a distance d 1 between two counterpart valves belonging to different reaction lines is constant, whatever the initial level (A, B or C) from which fluid transfers which are controlled by said counterpart valves are performed, and a distance d 2 between the two valves belonging to the same reaction line is constant from one reaction line to another.
