The CLA® Allergen-Specific IgE Assay

The CLA® Pette

048-2

The fundamental component of the system is the CLA Pette, a small plastic device that can measure the severity of a patient's allergic reaction to up to 36 different allergens, all using a single blood sample.

The CLA Allergy Test serves allergy patients worldwide —so every CLA Pette is geographically specific. Physicians select the panel appropriate for their patient.

  • Inhalant panel—pollen, dust, mites and other airborne allergens in the patient's region
  • Food panel—commonly ingested foods, such as milk, tomato, soybean or wheat
  • Combination panel—up to 36 of the most prevalent food and inhalant allergens overall

Inside every CLA Pette are up to 36 cellulose threads, each containing a selected allergen. The patient's blood sample is drawn and the serum is separated and aspirated into the device. IgE-specific antibodies in the serum bind to the allergens in the threads that trigger an allergic reaction. The technician then adds additional reagents to the panel, which produces light proportionate to the response. The results are determined by loading the CLA Pette into the CLA-1™ Luminometer.
