- No warming required—run directly from the freezer.
- SDMA tests can be stored at room temperature for up to 8 hours.
- After 8 hours, store SDMA tests in the freezer.
Recommended sample volume:
- Whole blood: 600-800 µL
- Serum/plasma: 100 µL
(65 µL minimum; 300 µL if running with other slides)

Frequently asked questions
| Question | Answer |
|---|---|
| Do I need to run anything with the SDMA slide? | SDMA can be run alone as a single slide. |
| What sample types can be run on the SDMA test? | Compatible sample types include serum, lithium heparin plasma, and whole blood using the Catalyst* Lithium Heparin Whole Blood Separator. |
| Can I run previously frozen samples on the SDMA test? | No, frozen samples should not be used when running the Catalyst SDMA Test. |
| Which species have been validated for the SDMA test and what are the numerical results? | Canine and feline species are supported with SDMA. Numerical results between 0–100 µg/dL will be reported. |
| Can SDMA be run with other slides? | Yes! The test can be run alone or with other slides as part of a comprehensive patient profile. For example, you could 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. |
| When running with other slides, should the SDMA test be loaded in a particular order? |
|
| What is the run time for the SDMA test? | SDMA results are available ~8 minutes after the start of the run. |
| Is it okay to dilute samples that are undergoing SDMA testing? | IDEXX does not support the use of diluted samples when running the Catalyst SDMA Test. |
| How often can SDMA tests be left at room temperature and then returned to the freezer? | Once at room temperature, SDMA tests can be returned to the freezer up to 5 times as long as they are unopened. |
| What if an SDMA test is accidentally refrigerated? | Any test suspected of being refrigerated should be discarded. |
| Which quality control should I use to monitor the performance of the SDMA test? | VetTrol* Control is designed for use in monitoring the accuracy of the Catalyst Dx and Catalyst One analysers. IDEXX also recommends monthly analyser maintenance to ensure the accuracy of these analysers. |
