Preparing to run a LQC test

Before running a LQC test you will need to prepare the control

solution using the materials provided in your Siemens Xprecia™

Systems PT Controls kit. To do this:

Open a plasma and diluent bottle

Remove the screw caps from the

plasma bottle and from one of the

diluent bottles.

Add diluent to plasma

Transfer the full contents of the

diluent bottle into the bottle of

plasma using a transfer pipette. Take

care to leave the diluent bottle as

empty as possible. Save the transfer

pipette to use during the LQC test.

Mix the solution

Screw the cap back onto the plasma

bottle firmly and carefully mix the

solution by swirling the vial in a

circular motion until the solution is

completely dissolved. To prevent

foam, do not shake the vial.

Wait at least 5 minutes before using the mixed solution.

You will need to use the solution within 25 minutes (if you keep the lid firmly

closed).

If necessary, you can store the mixed solution for 60 minutes in a

refrigerator at 2–8°C (36–46°F).

Gently swirl the vial again prior to use.
