The CardioChek Plus Test System and Operating Principle
The CardioChek Plus test system consists of three main parts. These include the
CardioChek Plus analyzer, PTS Panels test strips, and a lot-specic MEMo Chip.
The analyzer employs both light reectance and electrochemical biosensor technology
to measure an enzymatic chemical reaction. When a blood sample is applied to a
reectance test strip, a chemical reaction occurs that produces a color change on the
test strip. When blood is applied to an electrochemical test strip, an electrical current is
produced. This color or current is measured and compared to a calibration curve stored
in the lot-specic MEMo Chip. The analyzer converts this color or current reading into a
test result (the darker the color or greater the electrical current, the higher the analyte
concentration). The test result appears on the display screen.
