SDMA Test Catalyst Total T4 Test

Product Information

The Catalyst SDMA Test and Catalyst Total T4 Test are diagnostic tests used to assess specific markers in animal samples. The Catalyst One and Catalyst Dx are analyzers designed to perform these tests efficiently.

Storage and Handling Requirements

The Catalyst SDMA Test slides must be stored at room temperature, while the Catalyst Total T4 Test slides should be stored in a refrigerator or freezer. The accompanying reagents should also be stored according to their respective requirements.

Frequently Asked Questions

• Question: Do I need to run anything with the SDMA or TT4 slide(s)?
  Answer: The SDMA test can be run alone as a single slide. However, when running the TT4 test, the slide must be accompanied by the appropriate reagent.

• Question: What sample types can be run on the SDMA or TT4 test(s)? Can I run previously frozen samples on the SDMA or TT4 test(s)? Which species have been validated for the SDMA or TT4 test(s) and what are the numerical results? Answer: The compatible sample types for both tests include serum, lithium heparin plasma, and whole blood using the Catalyst Lithium Heparin Whole Blood Separator. Previously frozen samples should not be used for the Catalyst SDMA Test or both the Catalyst SDMA and Catalyst Total T4 tests. The validated species and their corresponding numerical results can be found in the product documentation.

• Question: Can SDMA or TT4 be run with other slides?
  Answer: Yes, SDMA and TT4 slides can be run with other slides. There is no specific order in which they need to be loaded.

• Question: What is the run time for the SDMA or TT4 test(s)?
  Answer: The SDMA test results are available approximately 8 minutes after the start of the run, while the TT4 test results are available approximately 15 minutes after the start of the run.

• Question: Is it okay to dilute samples that are undergoing SDMA or TT4 testing?
  Answer: No, IDEXX does not support the use of diluted samples when running the Catalyst SDMA Test or Catalyst Total T4 Test.

• Question: How often can SDMA or TT4 tests be left at room temperature and then returned to the refrigerator/freezer?
  Answer: SDMA tests can be left at room temperature and returned to the freezer up to 5 times as long as they remain unopened. TT4 tests can be returned to the refrigerator after being at room temperature, as long as they are unopened.

• Question: What if the SDMA or TT4 tests are stored improperly?
  Answer: Any SDMA or TT4 tests that have been stored improperly should be discarded to ensure accurate results.

• Question: Which quality control should I use to monitor the performance of the SDMA and TT4 tests?
  Answer: VetTrol Control is designed for use in monitoring the accuracy of the Catalyst Dx and Catalyst One analyzers. IDEXX also recommends monthly analyzer maintenance to ensure accurate results.

Storage and handling requirements

• Catalyst* SDMA Test: Store in the freezer (do not store in the freezer door).
• Catalyst* Total T4 Test: Store in the refrigerator. Do not freeze.
• No warming required—run directly from the refrigerator (TT4) or freezer (SDMA).
• SDMA and TT4 tests can be stored at room temperature for up to 8 hours. After 8 hours, store SDMA tests in the freezer and TT4 tests in the refrigerator.
• Recommended sample volume:
  • Whole blood: 600–800 μL
  • Serum/plasma: 100 μL (65 μL minimum; 300 μL if running with other slides)
