Limitations of the Procedure

SECTION 7

1. PRESERVATIVES:

Fluoride – Do not use fluoride as a preservative for blood specimens.
Iodoacetic acid – Do not use iodoacetic acid as a preservative for blood specimens.

2. ARTERIAL SPECIMEN: Arterial specimens with pO

2

of >200 mmHg had a small bias

(average of –6%) on the Ascensia E

LITE

in comparison to the laboratory method

glucose results. The reference range for arterial pO

2

is 80 to 110 mmHg (11.04 to

14.36 kPa).

3. NEONATAL USE: This Ascensia E

LITE

Blood Glucose Meter is not qualified for testing

neonatal blood specimens.

4. METABOLITES: Reducing substances such as ascorbic acid and uric acid at normal blood

concentrations do not significantly affect Ascensia E

LITE

Blood Glucose Test results.

5. HEMATOCRIT: At normal glucose levels, Ascensia E

LITE

Test Strip results are not

significantly affected by hematocrits in the range of 20% to 60%. At glucose levels
above 300 mg/dL (16.7 mmol/L), hematocrit levels above 55% will cause lowered results.

6. LIPEMIC SPECIMEN: Cholesterol up to 500 mg/dL (13.0 mmol/L) or triglycerides

up to 3000 mg/dL (33.9 mmol/L) do not significantly affect the results. Glucose val-
ues however, in specimens beyond these levels should be interpreted with caution.

CONTRAINDICATION: Fingerstick blood glucose testing may not be clinically appropriate when
peripheral blood flow is decreased. Shock, severe hypotension, hyperosmolar hyperglycemia
and occurrence of severe dehydration are examples of clinical conditions which may adversely
affect the measurement of glucose in peripheral blood.
