Instrument Details
Automated reflex testing and re-testing
Reduces unnecessary tests and ensures test results are clinically relevant.
Development and stop solution compartments
System reagents on-board for between test doses
Test carrier loading, barcode scanning, and temperature-controlled
Efficient test-loading process for Phadia 250 tests designed for efficient use of the operator’s time, both for routine tests and STAT tests.
Climate-controlled processing chamber
Maintains a temperature of 37 C with low humidity for optimal ImmunoCAP allergy and EliA autoimmune testing conditions.
Barcode scanning of sample racks, samples, and ImmunoCAP and EliA carriers and reagents
Full traceability to ensure patient safety and minimize risk of manual errors.
Bottle storage tray, fixed pipe connection for water in, fixed drain connection, and automatic refill of the wash fluid
Efficient and ergonomic fluid-handling options, adaptable to the laboratory’s infrastructure and workflow needs.
Reagent loading, ImmunoCAP and EliA carrier loading, and starting the run
Less than 15 minutes’ operator time need to setup the system and start the run to produce up to 60 tests per hour.
Conjugate storage compartment, positions for calibrators, and curve controls
Allows for assay runs with up to six different methods in parallel for both EliA autoimmune disease tests (e.g., connective tissue disease, rheumatoid arthritis) and ImmunoCAP allergy tests.
Automated onboard dilution, dilution fluid storage, and dilution plates
Automated onboard dilution saves operator time, ensures consistency in results, and enables automated re-run of tests out of measuring range.
Instrument touchscreen, Phadia Prime Software, and status indicator light
Facilitates walkaway capability so the operator can perform other tests in the lab.
Sample loading area with LAS and LIS connectivity
Phadia 250 supports integration into a laboratory automation solution track from the main track, enabling streamlined workflow in the laboratory.
