Always known for technology and reliability, Hitachi offers the medical community an alternative means of diagnosing allergy in a timely manner and at a significantly lower cost than has traditionally been available. We're proud to present two accurate, easy to use serum tests for allergy: the CLA® Allergen-Specific IgE Assay and the OPTIGEN® Allergen-Specific IgE Assay.


The CLA-1™ Luminometer In Vitro Allergy Diagnostic System is counterpart to the CLA and OPTIGEN assays and completes the allergy testing process.

The AP 720S™ Semi-Automated In Vitro Allergy Diagnostic System is an innovative instrument that automates the OPTIGEN Assay.
