CHEM8+ Cartridges

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;

Heparinized whole blood collected in balanced heparin syringes or capillary

tubes, or;

Heparinized whole blood collected in evacuated tubes containing lithium

heparin, as long as the tubes are ﬁlled to capacity.

Troponin I/cTnI, ß-hCG and CK-MB Tests

cTnI and CKMB cartridges require the use of heparinized whole blood or

plasma samples collected in syringes or evacuated tubes containing lithium

or sodium heparin and ﬁlled to capacity, or;

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, ß-hCG or CK-MB readings.

•

Capillary tubes and direct skin punctures (e.g., ﬁngersticks) should not be used

with the cTnI, ß-hCG or CK-MB cartridge.

BNP Tests

•

BNP catridges 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.

Limitations

Interfering substances in the patient's sample may cause an increase or decrease in a

result. Refer to the Cartridge and Test Information Sheets and Technical Bulletins for

substances and/or conditions that may interfere with cartridge tests.

Charging Rechargeable Battery in External Recharge Compartment

Placing a rechargeable battery into the recharging compartment will automatically initiate

trickle recharging. The indicator light near the recharging compartment will be green when a

rechargeable battery is placed in the compartment.

STEP / ACTION

The battery pack has two labels: one for orientation in the handheld and one for

orientation in the Downloader/Recharger. With the label with the Downloader facing

up and the electrical contact end of the pack facing the contacts in the battery

compartment, insert the pack into the compartment as shown on the label.

To remove the battery after it is charged, back the pack out of the compartment.

Full recharge from a discharged state takes approximately 40 hours.

Caution

If you are using rechargeable batteries, use only rechargeable batteries and recharging

equipment supplied by your i-STAT distributor. Other batteries and rechargers may affect test

results and pose other hazards to operators and patients.

Cleaning the Handheld and Downloader

Please see Section 17 of the i-STAT 1 System Manual (Routine Care of the Analyzer &

Downloader) for instructions on cleaning and decontaminating the handheld and

downloader.
