1. A method of performing an analytical test on a test sample, the method comprising:
- initiating, by an analyzer, a test cycle of a test device, the test cycle comprising a plurality of steps for performing on the test sample the analytical test for at least one target analyte;
determining spatial orientation of the analyzer during the test cycle;
comparing the determined spatial orientation to a threshold operating spatial plane for the test device, wherein the threshold operating special plane is a predetermined threshold plane for operating the test device during the test cycle; and
providing an alert that at least one of instructs and illustrates corrective action including required movement of the analyzer to bring the spatial orientation of the analyzer during the test cycle within the threshold operating spatial plane in order to prompt a user to take the corrective action for the test device during the test cycle, when the determined spatial orientation exceeds the threshold operating spatial plane,wherein the analyzer comprises a processor, a computer readable memory, a non-transitory computer readable storage medium and program instructions, stored on the non-transitory computer readable storage medium for execution by the processor via the computer readable memory, to provide the alert and to receive the corrective action prior to the test cycle ending with a determination of a result of the analytical test.

Abstract
The present invention covers the integration and utility of accelerometer features into a clinical analysis system. For example, measurement of dynamic acceleration and orientation of a blood-testing instrument with respect to Earth'"'"'s gravitational field may be used to determine reliability of a test procedure and optionally to provide corrective elements thereof.

8. A method of performing an analytical test on a test sample, the method comprising:
-
initiating, by an analyzer, a test cycle of a test device, the test cycle of the test device comprising a plurality of steps for performing on the test sample the analytical test for at least one target analyte; determining motion of the analyzer during the test cycle; comparing during the test cycle the determined motion to a predetermined threshold for operating the test device during the test cycle; and providing an alert that at least one of instructs and illustrates corrective action including cessation or deceleration of movement of the analyzer to bring the motion of the analyzer during the test cycle within the predetermined threshold for the test device in order to prompt a user to take the corrective action for the test device during the test cycle, when the determined motion exceeds the predetermined threshold, wherein the analyzer comprises a processor, a computer readable memory, a non-transitory computer readable storage medium and program instructions, stored on the non-transitory computer readable storage medium for execution by the processor via the computer readable memory, to provide the alert and to receive the corrective action prior to the test cycle ending with a determination of a result of the analytical test. - View Dependent Claims (9, 10, 11, 16, 17, 18, 19, 20)
