The invention relates to a method for detecting contact of a pipetting needle in an in vitro diagnostic system. To this end, the pipetting needle, in an advantageous embodiment of the invention, should be cyclically charged by an electric voltage or current applied between the pipetting needle and a reference potential and discharged again by a subsequent electric connection between the pipetting needle and the reference potential. A characteristic variable for the current capacitance between the pipetting needle and the reference potential should be established from a number of measured values detected during the charging and/or discharging. A temporal curve of the characteristic variable should be monitored continuously based on a number of predetermined criteria and a contact signal should be generated if the predetermined criteria are satisfied.
