Note: The IDEXX Urine Protein:Creatinine Sample Preparation Kit prepares the
sample for the urine creatinine test so the VetTest analyzer can calculate the most
accurate and quantitative UPC ratio result.
Urine Sample Preparation
To prepare a urine sample:
Obtain a urine sample through cystocentesis.1.
$FOUSJGVHFUIFTBNQMFPOBiVSJOFwTFUUJOHGPSBTQJOUJNFPGTFDPOET2.
Transfer the supernatant to an untreated collection tube or a sample cup using a 3.
VetTest transfer pipette (or any other pipette). During this process, it is important
that you do not aspirate any of the sediment, if present.
Run the UPRO slide on the VetTest analyzer.
While the UPRO test is running, use the sample preparation kit to properly
prepare the sample for the UCRE slide analysis. See the kit’s package insert
for instructions.
Run the UCRE slide using the prepared sample.

Sample Storage
IDEXX recommends that you process and analyze samples immediately after collection
for best results. However, if storage is necessary, follow these sample storage and
testing guidelines.
Storing Serum or Plasma Samples
For storage, the serum or plasma must be separated and removed immediately from
the blood cells. Do not attempt to pour off the sample.

stage as this damages the serum proteins.
If you cannot perform analysis within four hours of drawing and processing the sample,

from the cells, see section H: Chemistry Description and Guide.

), and glucose (GLU) chemistry descriptions for
additional special handling and storage requirements.
