These advanced testing solutions help identify issues caused by an overactive or underactive thyroid and deliver results that make a difference.
A better way to diagnose thyroid conditions
Thyretain® BioAssays measure the stimulating antibodies in the blood to specifically verify Graves' disease. And Thyretain Turbo TSI Stimulating Reporter BioAssay is the only specific bioassay commercially available for detecting thyroid-stimulating immunoglobulin (TSI) with a one-hour incubation at room temperature, making it very efficient and cost-effective.
The earlier a diagnosis of thyroid conditions like Graves' disease is made, the more treatment options are available to a patient, resulting in better care and less complications.
Thyretain cell-based bioassays differentiate between the functional stimulating and functional blocking antibodies against the thyroid gland. This differentiation provides important information about the further course of the disease.1

Thyretain BioAssays help determine the presence of stimulating and inhibiting autoantibodies against the thyroid gland using an enzyme reaction (luciferase bioassay).1 This is of considerable importance, since the clinical activity and the severity of the disease in patients correlate very well with the measured antibody values when using our luciferase bioassay.2
