The Diamine Oxidase (DAO) blood test evaluates histamine breakdown in the intestine, aiding in diagnosis and management of associated symptoms.
**Please note: **This test is available in Ireland; however, due to the time-sensitive nature of the sample, it must be shipped directly to the laboratory in Germany. A shipping fee of €60 applies.
An invoice will be issued to the practitioner at the point of purchase. If shipping has already been paid, that amount will be deducted from the final shipping cost.
Tested Biomarkers
Methodology
Diamine Oxidase (DAO) is analysed by enzyme-linked immunosorbent assay (ELISA) which is a widely used biochemical technique for detecting and quantifying the presence of antibodies, antigens, proteins, hormones, and other molecules in biological samples. In ELISA, a specific antigen or antibody is immobilized on a solid surface such as a microplate well. The sample containing the target molecule is added to the well, allowing any complementary molecules to bind to the immobilized antigen or antibody. After washing away unbound molecules, a secondary antibody conjugated with an enzyme is added, which binds specifically to the target molecule. Subsequent addition of a substrate for the enzyme leads to a colour change or fluorescence, which is measured spectrophotometrically. The intensity of the colour or fluorescence is directly proportional to the amount of target molecule present in the sample, enabling qualitative and quantitative analysis.
When should you conider this test?
Consider the DAO test for individuals with allergy-like symptoms, aiding dietary adjustments to reduce histamine intake. Additionally, consider it for chronic inflammatory bowel diseases, gastritis, irritable bowel syndrome, stomach ulcers, and regular medication intake.
