1. A method for automatic taking of a specimen from a test object, comprising the steps of:

  • moving a specimen collector, by means of a guiding device, to a specimen terminal attached to the test object;

    extracting a fluid specimen from the test object to the specimen collector;

    moving The specimen collector, by means of the guiding device, to an output position;

    outputting the specimen from the specimen collector, wherein the guiding device mechanically guides the specimen collector between the specimen terminal and said output position;

    moving the specimen collector by way of a first branch of the guiding device to and from the specimen terminal;

    moving the specimen collector by way of a second branch of the guiding device to and from the specimen container, wherein the specimen collector is moved from the first branch to the second branch via a guiding path switch, wherein the specimen collector comprises an inner tubing that extends inside an outer tubing comprised in the guiding device, the outer tubing having a first end arranged at said specimen terminal and a second end arranged at said specimen collector, wherein the specimen collector is displaced through a first tubing branch of the outer tubing to and from the specimen terminal and through a second tubing branch to and from the specimen container;

    moving the inner tubing to a position in a first part of the outer tubing proximal said guiding path switch;

    actuating the guiding path switch to join the guiding path of said first tubing part with a selectable guiding path of said first tubing branch or second tubing branch; and

    moving the inner tubing via said guiding path switch into a selected first or second tubing branch.
