CLA^® Pette
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 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 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 Pette into the CLA-1™ Luminometer.

CLA-1™ Luminometer
This state-of-the-art-patented device reads prepared Pette panels, measuring the intensity of the signal emitted by each allergen thread. In eight minutes, it can analyze up to 180 allergens!

The compact CLA-1 Luminometer automatically prints a complete report that lists the tested allergens and the severity of the patient's response to each. Easy to use and understand, the system is the simplest, quickest and most convenient allergy testing method available today.
