Blood Collection
Acceptable Samples for Cartridges
Arterial: Plain syringe, heparinized syringe labeled for analytes to be tested
and filled to capacity, or syringe with minimum volume of heparin to prevent
clotting (10 U/mL of blood). For ionized calcium, use balanced heparin
syringes. Mix heparinized syringes by rolling between palms for at least
5 seconds in 2 directions, then invert the syringe repeatedly for at least 5
seconds. Test for lactate immediately. Samples for pH, PCO2, PO
and ionized calcium should be tested within 10 minutes. Test for other
analytes within 30 minutes.
• Avoid drawing air into syringes for blood gas and ionized calcium tests.
• If not tested immediately, remix and discard 2 drops of blood before
filling cartridge.
• Do not use iced samples.
Venous: Collection tube with lithium or sodium heparin filled to capacity
and mixed by gentle inversion at least 10 times. Test within 10 minutes.
• Do not leave tourniquet on for more than 2 minutes.
• Do not draw above an I.V.
Skin puncture: Lithium heparin capillary tubes for testing all analytes but
ionized calcium. For all analytes including ionized calcium, use plain or
balanced heparin capillary tubes. Test immediately.
• Allow alcohol to dry over puncture site before collecting sample.
• Do not “milk” finger or heel while collecting sample.
Coagulation Tests:
• The ACT test can be performed using venous or arterial samples, while
the PT/INR test can be performed using capillary or venous samples.
• Use plain plastic syringes or plastic evacuated tubes with no
anticoagulant, activators, or serum separators.
• Test sample immediately upon draw.
• For venipuncture, some experts recommend drawing and discarding
a sample of at least 1 mL prior to drawing samples for coagulation
testing.
• If a second measurement is needed, draw a fresh sample.
• For In-dwelling line testing for ACT:
a. Fluid drip through the line must be discontinued.
b. Withdraw 2 mL of blood into a syringe and discard it.
c. Withdraw the sample into a fresh plastic syringe with no
anticoagulant, and test immediately.

• For extracorporeal line testing for ACT:
a. Flush the extracorporeal blood access line by withdrawing 5 mL of
blood into a syringe and discard the syringe.
b. Withdraw the sample into a fresh plastic syringe with no
anticoagulant, and test immediately.
• For skin puncture testing for PT/INR, see the section on "Patient Test
Procedures".
CHEM8+ Cartridges
• CHEM8+ cartridges require the use of:
a. whole blood collected in non-heparinized capillary tubes,
evacuated tubes, or syringes, as long as sample is tested
immediately upon draw,
b. heparinized whole blood collected in balanced heparin syringes or
capillary tubes, or
c. heparinized whole blood collected in evacuated tubes containing
lithium or sodium heparin, as long as the tubes are filled to
capacity.
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, 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.
• Samples should not be used unless the blood collection tube is filled at
least half full.
BNP Tests
• BNP cartridges require the use of EDTA whole blood or plasma
samples collected in plastic syringes or evacuated tubes containing
EDTA.
• The use of whole blood or plasma samples containing other
anticoagulants such as oxalate and citrate is not reccommended.
• When drawn into an evacuated tube containing EDTA, samples should
not be used unless the blood collection tube is filled at least half full.
• Capillary tubes and direct skin punctures (e.g. fingersticks) should not
be used with the BNP cartridge.
