1. Power ON the ACT Plus
actuator heat block to reach a temperature of 37.0°C ±0.5°C.
Note: When the heat block temperature is less than 36.0°C the software will
not allow a patient test to be initiated. The message "Heat Block Lockout
<36.0°C" is displayed.
2. From the Main Menu, select [Cartridge Type]. Continue to press this key until
the correct cartridge is selected. Press [Enter] to confirm.
3. Prewarm the cartridges for at least 3 minutes before collecting the test
sample. Cartridges for HR-ACT, LR-ACT, and RACT may be prewarmed for
up to 12 hours without affecting performance. For specific information, consult
the package insert that accompanies each cartridge.
4. Tap the cartridge to resuspend the reagent in the chamber before adding the
test sample.
5. Fill each cartridge chamber with the appropriate sample volume. The sample
level should be between the upper and lower fill lines in each reaction
chamber. Allow the sample to flow down the back of the chamber, taking care
to avoid getting the sample on the plunger tang (see Figure 1).
6. Insert the cartridge into the actuator heat block and rotate the block to the
closed position.
7. Reagent is delivered into the reaction chamber, and the time to clot formation
is measured.
8. When clot formation is detected, or if the test is terminated, an audible tone
sounds, and the actuator heat block automatically rotates to the open
position.
