An apparatus for moving and testing biological samples, comprising: - a laboratory automation system for moving transporting devices of single test tubes containing biological material samples, said laboratory automation system comprising a lane; - a testing module of said biological material samples contained in said test tubes adapted to receive linear containers of a plurality of test tubes arranged in a series of consecutive housings along a line; - an interconnection module between said laboratory automation system and said testing module allowing the linear containers to enter/exit in/from the testing module with a translating motion in the direction of said line, said interconnection module comprising at least one gripping device (6, 7) of said single test tubes, for picking said single test tubes from said transporting devices which are stationary along said lane of said laboratory automation system, said lane being adapted to interface with said interconnection module, and for placing said single test tubes in said housings of said linear container waiting on said interconnection module; wherein said interconnection module is configured as a transit and sorting area, which moves said test tubes from said automation system to said testing module and vice versa, and comprises: - an inlet point of said test tubes from said lane of said laboratory automation system; - an outlet point of said linear containers containing said test tubes to said testing module; - a re-inlet point, separated from said outlet point, of said linear containers from said testing module; - a first conveyor belt adapted to move said linear containers along said line from the inlet point to an end point of the first conveyor belt wherein said interconnection module further comprises a translator located at the end point of the first conveyor belt configured to displace said linear containers in a direction orthogonal to said line, to said outlet point; - a second conveyor belt adapted to move said linear containers along said line from said re-inlet point toward the laboratory automation system; - a pusher adapted to continuously move empty linear containers towards said inlet point, in a direction orthogonal to said line in an opposite versus with respect to the displacement of the linear containers to the outlet point by said translator. - a laboratory automation system for moving transporting devices of single test tubes containing biological material samples, said laboratory automation system comprising a lane;
