1. A portable clinical system for performing an immunoassay on a biological sample, the system comprising:
- a test device comprising a sample entry port and a sensing region comprising an immunosensor for performing the immunoassay on the biological sample, which generates an electric signal based on a concentration of an analyte in the biological sample determined by the immunoassay; and
an analyzer to initiate a test cycle of the test device, including performance of the immunoassay, comprising;
a processor, a computer readable memory, and a non-transitory computer readable storage medium;
a port to receive the test device;
an accelerometer to collect data during the test cycle;
program instructions stored on the non-transitory computer readable storage medium for execution by the processor via the computer readable memory, the program instructions comprising;
program instructions to determine motion of the analyzer during a test cycle of the test device based on the data collected by the accelerometer during the test cycle;
program instructions to compare the determined motion to a threshold rate of motion for the test device; and
program instructions to at least one of;
(i) provide an alert prompting a user to take corrective action during the test cycle, (ii) correct a result of the immunoassay, and/or (iii) suppress the result of the immunoassay, when the determined motion exceeds the threshold rate of motion.

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.
