Immunoassay Testing

South San Francisco, CA — Tosoh Bioscience, Inc. has announced that calibration curve stability for most Tosoh AIA assays has been extended to 90 days.  Improved calibration curve stability is made possible through Tosoh’s AIA-Pack Unit Dose Test Cup reagent technology.

Tosoh’s AIA-PACK test cups are single, unitized cups that utilize a dry reagent format which requires no pre-mixing, no pre-measuring, no on-board refrigeration and no waste.  The test cup format is used on all Tosoh AIA automated immunoassay analyzers, including the AIA-2000 (200 tests per hour), AIA-1800 (180 tests per hour), AIA-600 II (60 tests per hour), and AIA-360 (36 tests per hour).

Calibration is an extremely important step in immunoassay testing as the value reported is a quantitative estimate of concentration by direct comparison with a calibrator material.  The aim of calibration is to improve the accuracy.  Reducing the frequency of calibration helps laboratories to reduce overall costs and technician time.

Tosoh’s extensive immunoassay test menu provides a wide range of immunoassay tests including thyroid, cardiac markers, tumor markers, reproductive hormones, anemia markers, metabolic markers and more.  All Tosoh AIA-PACK assays now carry 90 day calibration curve stability with the exception of Troponin I, B12 and Folate, which will continue to have the 30 day calibration stability.

AIA-PACK test cups and trays are labeled with code and lot number for automated scheduling and inventory management.   A 10 minute incubation protocol provides fast turnaround time.  Additionally Tosoh AIA reagents have a shelf life of 1 year from the date of manufacture.

Because AIA-PACK test cup reagents are interchangeable on all Tosoh AIA systems, inventory management is easy and problem free.  Transition from one system to another is seamless, ensuring consistent results and efficient, economical operation for the laboratory.

Tosoh Bioscience, Inc. (TBI) provides highly sophisticated diagnostic systems for immunoassay and HPLC testing to doctor’s offices, hospitals and reference laboratories throughout the Americas.  Based in South San Francisco, CA, TBI is a U.S. subsidiary of Tosoh Corporation’s Bioscience Division, headquartered in Tokyo, Japan.

Tosoh Bioscience has introduced its latest advancement in high throughput immunoassay testing with the AIA-2000 Automated Immunoassay Analyzer. The anticipated new system builds upon Tosoh’s industry-earned reputation as a trusted developer of accurate and reliable analyzers for immunoassay testing.

Tosoh has added new functionality to the AIA-2000 to increase workflow and minimize time. The user can load up to 960 tests (48 trays) in a new, easy to load hybrid sorter; increasing walk-away time to approximately 4 hours. Tip capacity has been increased to 576, and can be added or changed at any time at the user’s request. Sample racks can be loaded with any combination of 200 bar coded primary tubes or sample cups.

The AIA-2000 features fully automated daily maintenance and record keeping, automatic inventory management and automated pre-treatment for assays that require this step. In addition, the analyzer features a 17-inch touch screen panel and improved user interface, allowing easy access to most of the controls from the screen. Multiple robotic arms, new staging platforms and mechanical adjustments speed the overall sample processing. As with all AIA systems, Tosoh’s reagent test cup technology produces accurate and consistent results, requiring no on-board refrigeration, no pre-mixing, and no pre-measuring.

AIA-2000 system features include: throughput of 200 tests/hour, 576 tips (6 tip racks), 2 substrate bottles, walk away time of 4 hours, 3 incubators with different processing steps, 2 sampling arms for faster processing of second reagent, and a full test menu.
The Tosoh booth at AACC 2009 (#3140) will feature the AIA-2000 in addition to an established line of state-of-the-art analyzers for immunoassay and HPLC testing. Tosoh will sponsor educational seminars by David Plaut on the booth stage and a Tosoh AACC 2009 Giveaway which includes a Tosoh tote bag or 1 Gig USB Flash Drive with Product Demonstration. The Tosoh AACC 2009 Giveaway is limited to one gift per AACC attendee, while supplies last.
