Immunoassay Testing

Immunoassay Reagents

Tosoh’s AIA-PACK test cup immunoassay reagent format works with every Tosoh AIA Automated Immunoassay System.

Interferences in Immunoassays, Part 1

Substances that alter the measurable concentration of the analyte or antibody (Ab) binding result in immunoassay interference. Interferences can be of 2 types – analyte dependent and analyte independent.

RBC Folate

B12 and folate are typically ordered to help diagnose the cause of macrocytic anemia. It is usually ordered as a follow-up when there is a large number of RBCs and decreased hemoglobin during a routine CBC.

Reproductive Immunoassays in IVF clinics

In-vitro fertilization (IVF) and intra-uterine insemination (IUI) are the most common methods used by fertility clinics. The overall goal of IVF treatment is to increase the number of follicles, prevent premature ovulation (reduce LH) and create the conditions for successful implantation of a fertilized egg.

Tosoh Launches Vitamin D Assay

Tosoh Bioscience, Inc. introduces the ST AIA-PACK 25-OH Vitamin D assay for use on Tosoh AIA System Analyzers*. Vitamin D measurement is intended as an aid in the determination of Vitamin D sufficiency.

Vitamin D Product Focus: Don’t Underestimate Vitamin D

25-OH Vitamin D is a challenging analyte to accurately measure in human blood due to presence of 25-OH Vitamin D2, Vitamin D binding proteins and Vitamin D metabolites. Variability between different methods due to lack of standardization has added to the challenges. The Tosoh ST AIA-PACK 25-OH Vitamin D assay correlates well with gold standard methods and measures equimolar concentrations of 25-OH Vitamin D2 and D3.

AIA-2000 Automated Immunoassay Analyzer Provides High Throughput Immunoassay Testing

Tosoh Bioscience delivers 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.

Immunoassay Testing News: Tosoh Extends Calibration Stability on Most Assays to 90 days

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.
