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.

(March 18, 2009) Immunoassay testing Video Blog post from Tosoh Bioscience features David Plaut and Bill McLellan discussing PTH on the AIA-360 Automated Immunoassay Analyzer at last year’s AACC in Washington, DC.


The intended use of the iPTH is for quantitative measurement of the levels of parathyroid hormone in human serum and EDTA plasma.  Impressive features include CVs of < 4%, assay range from 1 to 2200, sensitivity of 1.0 pg/ml, and 90 day calibration stability.  The assay also boasts a 10-minute incubation time and less than 30 minutes total assay time, which includes time to spin the specimen to collect plasma. Tosoh’s Intact PTH assay was designed using Allegro as the reference method which is aligned to the NKF/K-DOQI guidelines.

The AIA-360 can be used as a dedicated system for Intact PTH.  The analyzer’s extremely compact size (16w x 16d x 21h) makes it an excellent fit for hospitals, nephrologists and dialysis clinics.  With a throughput of 36 tests per hour, the AIA-360 generates its first result in approximately 20 minutes.  The cost effective system utilizes the same 10-minute incubation, short time (ST) reagents as Tosoh’s AIA-600 II and AIA-1800.  With interchangeable reagents on all Tosoh 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.
