Abstract: A computer-implemented method for supporting maintenance of an apparatus for analyzing biological samples, the apparatus including at least one hardware component subject to maintenance, the method comprising: receiving a plurality of measurement results, each measurement result being derived from a measurement performed by the apparatus for analyzing biological samples on a biological sample or on a quality control sample, the plurality of measurement results including measurement results obtained at different times; computing a time series of a performance parameter from the plurality of measurement results, the performance parameter being indicative of an operational state of said at least one hardware component, the time series representing a period of time having a start time and an end time, the end time being no later than a current time; extrapolating, using a predetermined extrapolation model, the computed time series to obtain an extrapolated time series of the performance parameter, the extrapolate
