The CLA® Allergen-Specific IgE Assay

The system, which consists mainly of the CLA® Pette and the CLA-1™ Luminometer, simultaneously measures the severity of a patient’s allergic reaction to up to 36 different allergens using a single 1.5 ml serum sample.

The CLA Pette, a small plastic device, is the fundamental component of the system. Each device contains up to 36 cellulose threads, each bound with a selected allergen.

Counterpart to the CLA Pette, the CLA-1 Luminometer completes the allergy testing process. This bench-top instrument reads prepared CLA Pettes, measuring the amount of chemiluminescent light emitted by the reaction to each allergen. In less than ten minutes, it can analyze up to 180 allergens. The instrument automatically prints a complete report that lists the tested allergens and the severity of the patient’s response to each.

The CLA-1 Luminometer performs a self-diagnostic each time it is powered up to ensure correct results. FDA-cleared and CE-marked, it has shown consistent, reliable performance in laboratories around the world.

The system uses Hitachi’s patented chemiluminescence technology, one of the most sensitive detection systems available. This allows for the detection of very low levels of IgE in patient serum. Hitachi also holds patents on the CLA Pette and its binding technology.

The CLA Allergen-Specific IgE Assay serves allergy patients worldwide, so each panel is designed to be geographically specific. Physicians simply select the panel that’s most appropriate for their patient.

  • Inhalant panels – pollen, dust, mites and other airborne regional allergens.
  • Food panel – commonly ingested foods such as peanut, milk, tomato, soybean, wheat and others.
  • Pediatric panel – up to 36 of the most prevalent food and inhalant allergens overall.

The pre-determined panel format simplifies testing and reduces set-up time. It also eliminates inventory of individual allergens and decreases waste.
