In a network and a method for evaluating medical data, a disposable biochip is provided which contains a patient sample with multiple biomolecular markers, as well as a biochip identifier which characterizes the biochip. The biochip is inserted into a point of care test device, which reads the biochip identifier. The point of care test device transmits the data characterizing the biochip to a remote server having access to a data bank in which a large number of measurement protocols are stored, and which selects one of the measurement protocols for testing the sample based on the transmitted data characterizing the biochip. The measurement protocol is transmitted back to the point of care test device via the data link, where the sample is tested using the measurement protocol. The test results are evaluated in an expert system, and a diagnostic result is displayed at the point of care test device.
