The development of immunoassay systems, using platinum group metals (pgms), in thyroid treatments has become increasingly complex in recent years.

Express Healthcare reports that the development has become more aimed at the precise and reliable non-isotopic assays, with chemiluminescent assays being modified and refined further into electrochemiluminiscent (ECL) assays.

These types of assays are known to occur with numerous molecules including compounds of various pgms, such as ruthenium and osmium.

One of the great benefits of using such assays is that they are so stable, according to Express Healthcare, while their enhanced sensitivity allows for a faster turnaround time. It also allows for early diagnosis of thyroid problems by enabling detection of all analytes.

ECL, a process of generating highly reactive species from stable precursors at the surface of an electrode, is based on ruthenium-tris complex and tripropylamine (TPA).
