Polymer Technology Systems, Inc. CardioChek Self-Test System (http://rbi.ims.ca/4911-548).This accurate, palm-sized self-blood test system allows users to determine their cholesterol levels (Total, HDL, and LDL) as well as measure glucose, ketones, and triglycerides in about a minute. The unit requires accurate temperature measurements to provide the correct results. The CardioChek uses the aSM121 SiMistor, a CMOS silicon thermistor, with integrated linear calibration from Andigilog that measures temperature to ±1C. The aSM121 measures the ambient temperature and allows the CardioChek to calibrate itself prior to determining the various levels in the sample.
