Thyroid Test
Xenopus Eleutheroembryonic Thyroid Assay
Tests are performed on whole organisms (newly hatched Xenopus eggs) exposed at the in vitro scale for 48h or 72h.
Alternative method replacing animal testing. Performed at an early eleuthero-embryonic stage.
Assay protocols adapted to your needs: regulatory, R&D, manufactured products portfolio screening.
The purpose of the XETA test is to measure the ability of a chemical to activate or inhibit the thyroid axis.
The XETA test has been shown to detect chemicals that act through different mechanisms of action.

Thyroid test used for regulatory purposes
The OECD classifies endocrine disruption according to 5 levels described in Guidance Document 150. The higher the level is, the stronger the weight of evidence.
The Level 3 XETA thyroid assay
The key point with level 3: it allows the use of alternative methods on whole organisms for some tests like the XETA assay.
To which ends do you want to perform thyroid tests?
Thyroid assay protocols can be adapted to fit your needs and to help you in your decision making process.
We also support you with building your testing strategy and understanding the data.
