1. A portable clinical system for in vitro analysis, the system comprising:

  • an analyzer configured to perform an in vitro analytical test on a sample obtained from a patient, the analyzer comprising;

    a port configured to receive a test device; and

    a computing device comprising at least one accelerometer and a processor, wherein the computing device is configured to;

    measure dynamic acceleration to determine motion of the analyzer;

    determine that the analyzer is in free fall based on the at least one accelerometer sensing the free fall as a predetermined value or was in free fall followed by a subsequent impact based on the at least one accelerometer sensing the free fall as the predetermined value and a sudden change in rate of acceleration after the free fall as the subsequent impact;

    lock the analyzer from performing the in vitro analytical test using the test device, when the analyzer is determined to be in the free fall or have been in the free fall followed by the subsequent impact;

    provide an alert prompting a user that a system performance verification is required to unlock the analyzer;

    provide a first time-stamp of when the analyzer is locked;

    perform the system performance verification on the analyzer;

    provide a second time-stamp of when the system performance verification is performed;

    store the first time-stamp and the second time-stamp such that there is a record of the analyzer being in free fall and that the system verification was performed; and

    ,unlock the analyzer after the system performance verification is performed successfully.
