- Analyte: Free triiodothyronine (FT3) in human serum and plasma.
- Total assay duration: 18 minutes (as specified by the manufacturer for Elecsys FT3 II).
- Platform compatibility: Roche cobas e immunoassay analyzers (e.g., cobas e 411, e 601, e 602, e 801 modules); confirm exact compatibility with the analyzer in use.
- Calibration: 2-point calibration using the dedicated Elecsys FT3 II CalSet.
- Traceability: Standardized against equilibrium dialysis reference method as stated by the manufacturer.
- Ready-to-use reagent cassette with streptavidin-coated microparticles, biotinylated T3-specific antibody and T3 labeled with ruthenium complex.
- Onboard and storage stability: As specified in the official Method Sheet / Instructions for Use.
Clinical Applications
- Quantitative determination of free triiodothyronine (FT3) as part of thyroid function assessment.
- Supports laboratory workflows investigating suspected hyperthyroidism and monitoring of thyroid disorders, in conjunction with TSH and FT4 testing, when used according to the manufacturer's intended use.
- Suitable for high-throughput clinical chemistry and immunoassay laboratories using Roche cobas e serology/immunoassay platforms.
