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
Glucometer Elite 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: The Glucometer Elite
®
XL System
is the only Glucometer Elite System qualified for neonatal
use. It is
intended for monitoring treatment
of hypo-
glycemia in neonates.The Glucometer Elite XL System
is
not intended for diagnosis
of neonates for hypoglycemia.
Do not use any other Glucometer Elite
®
Blood Glucose Meter
for neonatal testing.
4. METABOLITES: Reducing substances such as ascorbic acid
and uric acid at normal blood concentrations do not signifi-
cantly affect Glucometer Elite XL blood glucose test results.
5. HEMATOCRIT: At normal glucose levels, Glucometer Elite
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. For Neonatal Use: At glucose levels
between 20 mg/dL (1.1 mmol/L) and 120 mg/dL (6.7 mmol/L),
Glucometer Elite XL results are not significantly affected by
hematocrit levels in the range of 20% to 70%.
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 values, however, in specimens beyond these
levels should be interpreted with caution.
CONTRAINDICATION (Bayer advises against): Capillary
blood glucose testing may not be clinically appropriate when
peripheral blood flow is decreased. Shock, severe hypotension,
hyperosmolar hyperglycemia and occurrence of severe dehydra-
tion are examples of clinical conditions which may adversely
affect the measurement of glucose in peripheral blood.
