Check Room Temperature Storage Daily; Check Thermal Control System Every Six Months - Abbott i-STAT 1 System Manual

Check Room
Verify that the cartridges stored at room temperature are within the expiration
Temperature
date and that the cartridges have been out of the refrigerator less than the
Storage Daily
time frame indicated on the cartridge box. If the temperature at which the
cartridges are stored is in doubt, use controls to verify that the cartridges are
performing properly.
Check Thermal i-STAT analyzers contain a thermal control subsystem consisting of
Control System two thermal probes with thermistors and heating contact wires. When
Every Six Months measurements are performed at a controlled temperature, the thermal probes
in the analyzer contact the metalized area under the chips in the cartridge and
maintain the temperature of the sensors and the fluids that come into contact
with these sensors at the required temperature ± 0.15°C.
A quality check is performed on the thermal probes each time the external
Electronic Simulator is used. To complete this check, the surface temperature
of the external Electronic Simulator must not fluctuate. If this condition is not
met, the thermal probe check is not completed. Therefore, i-STAT recommends
that the thermal probe check be verified every six months.
