SGTi-Allergy Screen is an in-vitro diagnostic medical device that diagnoses allergies by semi-quantitating allergen-specific immunoglobulin E from serum or plasma by the enzyme immunoblotting method.

Various types of allergens are fixed to the membrane at regular intervals, and a specific antigen-antibody reaction occurs with the added solution, and a purple band is formed on the allergen band.

This band is analyzed using the optical detection system. The entire reaction performed automatically by the S-Blot3.
