A method and laboratory system for handling sample tubes and an image analysing unit are disclosed. The laboratory system comprises a transfer unit for transferring incoming primary racks (PR) containing sample tubes (S), an image analysing unit (310), and an identification and allocation unit. The method to handle laboratory sample tubes includes steps of: transferring an incoming primary rack (PR) containing sample tubes (S) to the image analysing unit (310); determining, in the image analysing unit (310), geometry parameters of at least one sample tube contained in the primary rack by means of image analysing; comparing for each sample tube the determined geometry parameters with predetermined geometry criteria and identifying whether the sample tube's geometry fulfils the predetermined criteria; in case of fulfilment, categorising the sample tube as system conform; otherwise categorising the sample tube as non-system conform. Each sample tube identified as system conform is entered into further processing and each sample tube identified as non-system conform is entered into error processing. |
