CHEM8+ Cartridges
a.
CHEM 8+ cartridges require the use of whole blood collected in non-
heparinized evacuated tubes or syringes, as long as sample is tested
immediately upon draw, or;
b.
Heparinized whole blood collected in balanced heparin syringes or capillary
tubes, or;

Troponin I/cTnI and CK-MB Tests
•
cTnI and CK-MB cartridges require the use of either:
a.
heparinized whole blood or plasma samples collected in syringes or
evacuated tubes containing lithium or sodium heparin and filled to capacity, or
b.
non-heparinized whole blood or plasma samples tested within one minute
of drawing from a patient into a plastic syringe or plastic evacuated tube
containing no additives.
•
The use of whole blood or plasma samples containing other anticoagulants such as
EDTA, oxalate, and citrate will cause deactivation of the alkaline phosphatase,
resulting in decreased cTnI or CK-MB readings.
•
Capillary tubes and direct skin punctures (e.g., fingersticks) should not be used
with the cTnI or CK-MB cartridge.
n
BNP Tests
•
BNP cartridges require the use of EDTA whole blood or plasma samples collected
in plastic syringes or evacuated tubes containing EDTA and filled to capacity.
•
The use of whole blood or plasma samples containing other anticoagulants such
as oxalate and citrate is not recommended.
•
Capillary tubes and direct skin punctures (e.g., fingersticks) should not be used
with the BNP cartridge.

Total ß-hCG Tests
•
Total ß-hCG cartridges require the use of heparinized whole blood or plasma
samples collected in plastic syringes or evacuated tubes containing lithium or
sodium heparin and filled to capacity.
•
The use of whole blood or plasma samples containing other anticoagulants such
as EDTA, oxalate and citrate will cause deactivation of the alkaline phosphatase,
resulting in decreased Total ß-hCG readings.
Interfering substances in the patient's sample may cause an increase or decrease in a result.
