3. PTS Diagnostics’ CardioChek Plus® Analyzer and Lipid + eGLU Test Strips Smart BundleTM Pack
Recognizing the linkage between heart attack, stroke, and diabetes, the CardioChek Plus analyzer provides rapid on-site lipid panel plus glucose results to help identify at-risk individuals. Handheld and battery-powered, the CardioChek Plus analyzer requires a small blood sample from a simple fingerstick. The capability to deliver both results in as little as 90 seconds enables healthcare professionals to improve their throughput, which is particularly important in today’s health promotion environment. The CardioChek family includes products for both professional and home use and is available in many global markets.

4. Principles of the Lipid Test (Reflectance)
Test results are based on readings of light reflected off a test strip that has changed color after blood is applied.
The intensity of the color is proportional to the concentrations of cholesterol, HDL cholesterol, and triglycerides in the sample.
The analyzer converts these reflectance photometry readings into cholesterol, HDL cholesterol, and triglycerides results and displays them.
The enzymatic reactions that occur are listed below.
Cholesterol
Cholesterol ester + H2O cholesterol esterase Cholesterol + fatty acid
Cholesterol + H2O + O2 cholesterol oxidase Cholesterol-4-en-one + H2O2
2H2O AAP + disubstituted aniline peroxidase quinoneimine dye + 4H2O
HDL Cholesterol
VLDL, LDL, HDL plasma VLDL, LDL, depleted plasma
Triglycerides
Triglycerides + 3H2O lipoprotein lipase glycerol + 3 fatty acid
Glycerol + ATP glycerol kinase Glycerol-3-PO4 + ADP
Glycerol-3-PO4 + O2 glycerophosphate oxidase Dihydroxyacetone-PO4 + H2O2
2H2O AAP + N,N-disubstituted aniline peroxidase quinoneimine dye + 4H2O

5. Principles of the eGLU Test (Electrochemical)
The eGLU test strips use electrochemical (amperometric) technology to produce a glucose result.
When blood is applied to the test strip, the blood starts a chemical reaction that produces an electrical current.
The current is converted into a glucose result and is displayed on the analyzer screen.
The enzymatic reaction that occurs is listed below.
Glucose
a) Glucose + GOx-FAD (ox) → Gluconolactone + GOx-FADH2 (red) [above electrode]
b) Kferri(ox) + GOx-FADH2 → GOx-FAD + Kferri(red) [above electrode]
c) Kferro(red) → Kferri(ox) [at electrode]
2Fe(CN)64- (ferro) → 2Fe(CN)63- (ferri) + 2e- (detection of ferro at carbon electrode
+400mV)

6. Measuring Range
Measuring Range: PTS Panels® lipid panel test strips will provide numeric results in the following ranges:
Cholesterol: mg/dL ( mmol/L, 1-4 g/L)
HDL Cholesterol: mg/dL ( mmol/L, g/L)
Triglycerides: mg/dL ( mmol/L, g/L)
Results below the test ranges will read “<___” (less than measuring range).
Results above these ranges will read “>___” (greater than measuring range).

7. Measuring Range
Measuring Range: The electrochemical glucose test system will detect glucose levels from mg/dL ( mmol/L, g/L) and will display a number value for results in this range.
If the display reads “<___” (less than measuring range), the glucose level is below 40 mg/dL (2.22 mmol/L, 0.40 g/L). Results above 600 mg/dL (33.3 mmol/L, 6 g/L) will read “>___” (greater than measuring range).
