How to run the Catalyst SDMA Test

How to run SDMA on a Catalyst One Chemistry Analyzer
  1. Enter the sample information on the IDEXX VetLab Station.
  2. Load the slides and sample in the sample drawer.
  3. Close the sample drawer and press the Start button on the analyzer.
How to run SDMA on a Catalyst Dx Chemistry Analyzer

1. Enter the sample information on the IDEXX VetLab Station.
2. Select the patient and sample type on your Catalyst Dx Chemistry Analyzer.
3. Load your sample, chemistry CLIP, and SDMA slide.
4. Load the reagent and tap Run on the analyzer.

Answers to common questions about the Catalyst SDMA Test

Running and analyzing the Catalyst SDMA Test is simple. Use these resources to answer your questions about the Catalyst SDMA Test.

Store the Catalyst SDMA Test in the refrigerator. There’s no need to warm the Catalyst SDMA Test. Just pull it from the refrigerator when you’re ready to run it.

The Catalyst SDMA Test and reagent can be stored in their pouch at room temperature for up to 8 hours. After 8 hours, store any unused materials in the refrigerator (do not freeze).

Absolutely. If you have a Catalyst One Chemistry Analyzer, the Catalyst SDMA Test can be run alone or with other slides as part of a comprehensive patient profile. For example, you can run a Catalyst Lyte 4 CLIP, a Catalyst Chem 17 CLIP, a Catalyst Total T4 Test and a Catalyst SDMA Test with one patient sample.

The Catalyst SDMA Test and the Catalyst Total T4 Test can also be run together by using the Catalyst SDMA and Total T4 Kit. On the Catalyst Dx Chemistry Analyzer, phenobarbital and CRP are the only tests you cannot run with SDMA.

You can load the slides in any order when running SDMA on the Catalyst One Chemistry Analyzer or with 18 or fewer slides on the Catalyst Dx Chemistry Analyzer. For the quickest time to results on the Catalyst One and Catalyst Dx chemistry analyzers, the recommended load order is Lyte 4 CLIP, chemistry CLIP (e.g., Chem 17, Chem 10), SDMA, total T4, with additional slides on top.

Note: Always be sure to load the drawer with pipette tips before every run.


The recommended sample volume to run the Catalyst SDMA Test depends on the type of sample you're using. For whole blood, we recommend 600–800 µL. If you're testing serum/plasma, we recommend 65 µL, or 300 µL to run SDMA with other tests.
