Estradiol G2 Elecsys 100T | REF 3000079190
Roche Elecsys Estradiol G2 immunoassay reagent kit, 100 tests, REF 3000079190, for use on compatible Roche cobas immunoassay analyzers.
The Roche Elecsys Free beta-HCG reagent (REF 4854071200) is an electrochemiluminescence immunoassay (ECLIA) designed for the in vitro quantitative determination of the free beta subunit of human chorionic gonadotropin (free β-hCG) in human serum. The assay is intended for use on Roche cobas e immunoassay analyzers and is commonly applied as part of first-trimester prenatal screening protocols in combination with other biochemical and ultrasound markers.
Key Features
- Methodology: Sandwich electrochemiluminescence immunoassay (ECLIA) using biotinylated monoclonal anti-β-hCG and ruthenium-labeled monoclonal anti-β-hCG antibodies.
- Specificity: Selective detection of the free beta subunit of hCG, minimizing cross-reactivity with intact hCG.
- Sample Material: Human serum; tube and volume requirements as specified in the official Method Sheet.
- Calibration & QC: Compatible with dedicated Elecsys CalSet and PreciControl materials supplied separately.
- Platform Compatibility: For use on Roche cobas e immunoassay analyzers as listed in the current Roche product matrix.
- Ready-to-use Reagent Pack: Cassette-format reagents for streamlined onboard handling and traceability.
Clinical Applications
- First-Trimester Prenatal Screening: Quantitative measurement of free β-hCG as part of combined screening strategies for fetal aneuploidies, used together with PAPP-A and ultrasound markers.
- Laboratory Workflow Integration: Routine use in centralized clinical chemistry and prenatal screening laboratories operating Roche cobas e immunoassay platforms.
- Risk Calculation Software: Results may be transferred to validated risk-assessment software for prenatal screening interpretation.
