The system of claim 5, wherein the test device comprises at least one sensor configured to detect at least one target analyte selected from the group consisting of: hematocrit, troponin, creatine kinase myocardial band (CKMB), brain natriuretic peptide (BNP), beta human chorionic gonadotropin (bHCG), carbon dioxide partial pressure (pCO.sub.2), partial pressure oxygen (pO.sub.2), pH, prothrombin time (PT), activated clotting time (ACT), activated partial thromboplastin time (APTT), sodium, potassium, chloride, calcium, urea, glucose, creatinine, lactate, oxygen, and carbon dioxide. 7. The system of claim 5, wherein the analyzer further comprises: program instructions to determine motion of the analyzer during the test cycle of the test device; program instructions to compare the determined motion to a threshold rate of motion for the test device; and at least one of: (i) program instructions to provide a different alert prompting the user to take different corrective action for the test device during the test cycle, and (ii) program instructions to suppress the result of the analytical test, when the determined motion exceeds the threshold rate of motion. 8. The system of claim 7, wherein the test device comprises at least one electrochemical sensor in a conduit. 9. The system of claim 7, wherein the test device is further configured to receive a sample comprising whole blood, and perform the analytical test on the sample. 10.
