II. INTRODUCTION TO THE CARDIOCHEK PLUS
PROFESSIONAL TEST SYSTEM, continued
Limitations
PTS Panels eGLU Test Strips
LIMITATIONS OF THE PROCEDURE
1. The analyzer should not be used to test critically ill patients.
2. Blood samples from patients in shock, patients with severe dehydration, or patients in a
hyperosmolar state (with or without ketosis) have not been tested. It is not
recommended to test those samples with this system.
3. PRESERVATIVES: Blood samples preserved with Fluoride or Oxalate should not be
used for testing with this system.
4. VENOUS SAMPLES: To minimize glycolysis, venous whole blood samples must be
tested within 20 minutes of the draw. Grossly lipemic samples may interfere with some
methodologies. Critically ill patients should not be tested by this method, or tested with
extreme caution.
5. NEONATAL USE and ARTERIAL BLOOD: This product has not been tested using
neonatal or arterial blood. This test system should not be used with these whole blood
samples. This test system is specific for glucose. Other sugars or reducing substances
such as ascorbic acid at normal blood concentrations have no significant effect on test
results. Acetaminophen (Tylenol) and dopamine may interfere causing the test result to
be higher than the actual glucose. Not every drug was tested.
6. METABOLITES: This test system is specific for glucose. Other sugars and other
reducing substances such as ascorbic acid at normal blood concentrations have no
significant effect on test results.
7. HEMATOCRIT: Hematocrit values above 55% or lower than 30% may incorrectly lower
the glucose result.
8. ALTITUDE: Testing at altitudes up to 5280 feet has no effect on results.
9. DEHYDRATION: Severe dehydration and excessive water loss may produce falsely low
results.
