To Prepare a Serum Sample
1. Use the appropriate tube and collection device.
2. Draw the sample gently and transfer if necessary.
3. Let the sample clot for a minimum of 20 minutes.
4. Centrifuge the sample.
5. Use a transfer pipette (or a 300 µL pipette) to transfer the appropriate volume of sample to a
Catalyst sample cup (ensure there are no bubbles in the sample cup). The volume needed
varies depending on the number of slides being used in the run—for more information, see
“Proper Sample Cup Volume” on page 22.
To Prepare a Urine Sample
1. Obtain the sample through cystocentesis (recommended), catheter, or free-catch method.
2. Transfer the sample to a disposable sample tube.
3. Centrifuge the sample.
4. Use a transfer pipette (or a 300 µL pipette) to transfer the appropriate volume of supernatant
urine to a Catalyst sample cup (ensure there are no bubbles in the sample cup). The
volume needed varies depending on the number of slides being used in the run—for more
information, see “Proper Sample Cup Volume” on page 22.
