The Science Behind ELISA / ACT Biotechnologies
ELISA / ACT Biotechnologies utilizes a well-established and highly sensitive immunological principle to detect allergens. The process begins by immobilizing allergens on a solid surface, such as a microplate. The immobilized allergens act as bait, waiting for the patient's blood sample to be introduced.
When a blood sample is added to the surface, any specific antibodies known as IgE antibodies present in the blood will bind to the immobilized allergens if the patient is allergic to any of them. This binding event is the key to ELISA's success. It allows for the detection and quantification of allergen-specific IgE antibodies, which are responsible for triggering allergic reactions.
To detect the bound antibodies, enzymes are introduced. These enzymes are conjugated to secondary antibodies that recognize and bind to the IgE antibodies. Once the secondary antibodies are bound, a color-changing substrate is added to initiate a reaction. The intensity of the resulting color change is directly proportional to the concentration of IgE antibodies in the blood sample. By measuring this color change, ELISA / ACT Biotechnologies provides healthcare professionals with valuable information about the presence and severity of allergies.

The process of Allergen-Specific IgE Blood Testing begins with a healthcare professional drawing a small blood sample from the patient. This sample is then sent to a specialized laboratory where it undergoes thorough analysis. Through advanced laboratory techniques, the presence and quantity of specific IgE antibodies are identified and measured.
It is important to note that the amount of IgE antibodies present in the blood directly correlates with the likelihood of an allergic reaction to a particular allergen. Therefore, the results of Allergen-Specific IgE Blood Testing provide valuable insights into a patient's allergic sensitivities.
How Allergen-Specific IgE Blood Testing Works
Allergen-Specific IgE Blood Testing involves a series of steps to accurately identify and quantify specific IgE antibodies. Once the blood sample is obtained, it is processed in the laboratory to extract serum, which contains the antibodies of interest.
The serum is then exposed to a panel of allergens, which may include common substances such as pollen, dust mites, pet dander, or certain foods. By observing the reaction between the serum and these allergens, healthcare professionals can determine the presence and levels of specific IgE antibodies. The results are typically reported as numerical values, indicating the concentration of IgE antibodies for each allergen tested.
Uses of Allergen-Specific IgE Blood Testing in Diagnosing Allergies
Allergen-Specific IgE Blood Testing serves various purposes in diagnosing allergies. It is particularly useful when other diagnostic methods, such as skin prick tests, are inconclusive or cannot be performed. In such cases, this blood test provides an alternative means of identifying allergens.
Furthermore, Allergen-Specific IgE Blood Testing can help identify allergens that may not produce an immediate reaction. Some allergic responses are delayed, making it challenging to pinpoint the exact triggers without specialized testing. By analyzing the levels of specific IgE antibodies in the blood, this test can detect sensitivities to allergens that may have been overlooked.
Moreover, Allergen-Specific IgE Blood Testing plays a crucial role in evaluating the severity of allergies.
