General

Notes:
Lot numbers and expiration dates for cartridges and controls must be entered
■
prior to running a test (refer to Data Entry on page 18 for detailed
instructions).
■ The User ID and Patient ID numbers must be entered prior to running a test
(refer to Data Entry on page 18 for detailed instructions).
1. Power ON the ACT Plus™ instrument. Allow at least 10 minutes for the
actuator heat block to reach a temperature of 37.0°C ± 0.5°C.
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 ACT 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 flag or the plunger assembly (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.
