OverviewZenit fast is the A. Menarini Diagnostics automated system for acquisition, analysis and storage of IFA slides. It standardizes and accelerates IFA workflows for clinical laboratories by combining rapid whole-well scanning, autofocus imaging, and dedicated analysis algorithms for ANA/ANCA/nDNA and tissue substrates.
Main features and benefits- Fast screening of negative and positive samples to prioritize laboratory workflow
- Slide scanning speed: < 30 s/well for HEp-2 at 20x; < 2.5 min/well for tissues at 20x
- Support for multirun sessions to process large batches
- 8-slide tray for parallel processing
- High-quality sensor with LED microscope illumination and whole-well autofocus
- Virtual microscope for detailed navigation and operator review
- Reduced operating time per sample and optimized throughput
Powerful and reliable information managementSoftware is organized into three modules: Scanning, Validation and Archive. Scanning accepts worklists and runs automatic or manual scans. Validation provides digitized image navigation with a virtual microscope, customizable multiview layouts, interpretation tools and direct LIS/HIS transfer upon validation. Archive enables patient and test retrieval with free-text search and advanced queries.
Automated image analysisAutomatic classification of positive/negative results (Zenit ANA HEp-2). Quantitative fluorescence intensity measures for positives and pattern recognition on identified results, including mitosis detection. Supports ANCA ethanol/formalin classification, nDNA positive/negative discrimination and DNA Crithidia interpretation.
Detected pattern recognition (high level)- Zenit ANA HEp-2: AC-0 (Negative), AC-1 (Nuclear homogeneous), AC-2/4/5/29 (Speckled), AC-3 (Centromere), AC-6/7 (Nuclear dots), AC-8/9/10 (Nucleolar), AC-15/16/17/18/19/20/22/23 (Cytoplasmic), AC-21 (Cytoplasmic reticular AMA)
- Zenit ANCA: Negative, c-ANCA, p-ANCA, Others
