Limitations of the measurement procedure
1. DO NOT use serum or plasma sample.
2. DO NOT use neonate blood sample.
3. Extreme humidity may affect the results. A relative humidity
greater than 90% may cause incorrect results.
4. The System is designed to be used at temperatures between
10°C and 40°C (50°F and 104°F). Outside this range, the sys-
tem may yield erroneous results.
5. DO NOT reuse the test strips. The test strips are intended for
single use only.
6. DO NOT use iodoacetic acid, uoride or sodium uoride/oxalate
as a preservative for blood specimens.
7. Hematocrit:
Test strip results are not signicantly affected by hematocrits
in range of 30% to 55%. Hematocrit levels less than 30% may
cause incorrect high readings and hematocrit levels greater
than 55% may cause incorrect low readings. If you do not know
your hematocrit level, consult your healthcare professional.
8. Interfering substances depend on the concentration. The sub-
stances below may affect the test results:
• Acetaminophen > 15 mg/dL or 1.0 mmol/L
• Geneticist Acid > 8 mg/dL or 0.5 mmol/L
• Levodopa > 10 mg/dL or 0.5 mmol/L
• Dopamine > 13 mg/dL or 0.7 mmol/L
• Methyldopa > 2.5 mg/dL or 0.12 mmoll/L
• Uric Acid >14 mg/dL or 0.4 mmol/L
