An automatic apparatus for obtaining and analyzing a blood sample contains a supply of lancets and test strips, which are located alternately on a carrier band. A lancet or alternatively a test strip may be clamped on a holder, which is mounted so it is movable. The movement controller of the holder comprises a three-dimensional control curve and a guide element, which engages at different depths in the control curve as a function of its relative position. The control curve comprises two guide paths, which run on different parallel planes. The contour of the first guide path determines the movement path of the lancet and the contour of the second guide path determines the movement path of the test strip. The test strip executes a transverse offset perpendicular to the puncture axis of the lancet.
