Allergy testing using photon counting techniques

A simple photon counting system capable of detecting the chemiluminescent emission levels from each thread of the MAST test chamber has been demonstrated. This has been used in the determination of allergen specific IgE in serum samples. The results obtained using this system agree with those obtained using the photographic system. The system is capable of measuring emission levels up to 20 hours after initiation of the enzymatic reaction. The new system is much faster and easier to use than the photographic system, and can be made into a one stage, compact system.<
