Allergy, Autoimmune Testing System
For medium-sized laboratories
Providing optimal allergy and autoimmunity testing using advanced technology, the Phadia 250 laboratory system from Thermo Fisher Scientific Inc, Waltham, Mass, is fully automated and designed for medium-sized laboratories. The unit is capable of delivering 400–2000 results per week, with a throughput of 60 results per hour. Information data manager software allows integration of several Phadia instruments into one network using the same software. The system offers a broad autoimmunity menu covering clinically relevant markers for evaluation of the most common autoimmunity diseases. The company recently received FDA premarket notification (510(k)) clearance for five new ImmunoCap allergen component tests, performed on Phadia systems, for detecting immunoglobulin E sensitization to cashew, hazelnut, and walnut proteins.

Includes 48 new, custom-driven features
Quanterix Corp, Lexington, Mass, has launched Simoa 2.0, the second generation of the company’s ultrasensitive immunoassay platform. Hardware improvements include a redesigned wash ring to prevent salt buildup, LED labeling above lanes, idle power management, and improved tubing routing to avoid wash-lift stalling. The platform also boasts 48 new, customer-driven features, such as blocking of sample processing if the database is at critical space level, a prompt for user status whenever a waste bin is removed, and the elimination of a restart requirement when switching between plate and rack modes. During the new assay protocol, the same number of beads as in the Simoa 1.0 assay protocol are mixed directly with the sample, with no pelleting step, thereby reducing the risk of inadequate resuspension of beads.

Benchtop Immunoassay System
Performs up to 36 tests per hour
The Vidas 3 from bioMérieux, Marcy l’Etoile, France, is the latest version of the company’s benchtop immunoassay system. The FDA-cleared and CE-marked instrument incorporates enhanced preanalytical automation features, including automated scanning of reagents and barcoded primary sample tubes for improved traceability, automated calibration and onboard dilution, and new software capabilities. The low-throughput immunoassay system can perform up to 36 tests per hour, on demand, individually, or in series. Calibration can be completed every 14 or 28 days, depending on the parameter. Three separate racks each containing three configurable segments can hold a total of 27 samples, diluents, and calibrators. Users have access to more than 100 tests in a single-test format for the diagnosis of allergies, cancers, cardiovascular diseases, infectious diseases, infertility, pregnancy, and thyroiditis.
