1. A portable clinical system for performing a hematocrit analysis, the system comprising:
- a test device comprising a hematocrit sensor configured to perform the hematocrit analysis, which includes generating an electric signal based on a hematocrit measurement of a biological sample; and
an analyzer comprising;
a port configured to receive the test device; and
a computing device configured to;
initiate a test cycle of the test device, the test cycle including performance of the hematocrit analysis;
determine spatial orientation of the analyzer during the test cycle of the test device;
compare the determined spatial orientation to a threshold operating spatial plane for the test device; and
when the determined spatial orientation exceeds the threshold operating spatial plane, provide an alert prompting a user to take corrective action, wherein the corrective action is taken without reinitiating the test cycle including the performance of the hematocrit analysis.

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.

16. A method of performing a hematocrit analysis, the method comprising:
-
inserting a test device comprising a hematocrit sensor into a port of an analyzer; initiating, by the analyzer, a test cycle of the test device, the test cycle including performance of the hematocrit analysis, wherein the performance of the hematocrit analysis includes the test device generating an electric signal based on a hematocrit measurement of a biological sample; determining spatial orientation of the analyzer during the test cycle of the test device; comparing the determined spatial orientation to a threshold operating spatial plane for the test device; and when the determined spatial orientation exceeds the threshold operating spatial plane, providing an alert prompting a user to take corrective action, wherein the corrective action is taken without reinitiating the test cycle including the performance of the hematocrit analysis. - View Dependent Claims (17, 18)

19. A portable clinical system for in vitro analysis, the system comprising:
-
a test device comprising at least one sensor configured to output a signal that is partially dependent on non-homogeneity of cells in a blood sample positioned in a region of the at least one sensor; and an analyzer comprising; a port configured to receive the test device; and a computing device configured to; initiate a test cycle of the test device that includes output of the signal; determine spatial orientation and motion of the analyzer during the test cycle of the test device, the test cycle including performance of a hematocrit analysis; compare the determined spatial orientation to a threshold operating spatial plane for the test device; compare the determined motion to a threshold rate of motion for the test device; and when at least one of (i) the determined spatial orientation exceeds the threshold operating spatial plane, and/or (ii) the determined motion exceeds the threshold rate of motion, provide an alert prompting a user to take corrective action, wherein the corrective action is taken without reinitiating the test cycle including the performance of the hematocrit analysis. - View Dependent Claims (20, 21)
