Elecsys^® Tg II

The main application for Thyroglobulin (Tg) testing is the post‑operative follow‑up of patients with differentiated thyroid carcinoma (DTC). Detectable levels of serum Tg after total thyroidectomy are indicative of persistent or recurrent DTC.¹

• Improved sensitivity comes with better precision in the range around the clinical cut-off and improved negative predictive value³
  
• Sensitive Tg assays can avoid TSH-­stimulated Tg testing during follow-up, in low-risk patients¹
  
• Patients with a basal Tg below the ­functional sensitivity of a sensitive Tg ­assay have a high chance of being free of disease²
  
• High quality patient results and accurate long-term monitoring

Excellent precision across the entire ­measuring range supports accurate results³

• Lot-to-lot consistency across all cobas® platforms allows a reliable long-term ­patient monitoring
• Elecsys^® Tg II shows lower TgAb interference, compared to other assays¹
• Higher sensitivity allows for potentially earlier detection of persistence or recurrence

Increasing concentrations of Tg (even at low concentrations) are an early and reliable indicator of recurrent disease¹

• Treatment is usually more successful with early detection, as the tumor burden is lower¹
