Carmine Red Dye IgE Allergy Blood Test
The Carmine Red Dye IgE Allergy Blood Test measures the IgE antibody levels in the blood to detect an allergy to carmine red dye.
What is the purpose of this test?
Order this Carmine Red Dye IgE Allergy Blood Test, which measures the IgE antibody levels in the blood to detect an allergy to carmine red dye. Carmine red dye is a natural red color made from dried female insects found on prickly pear cactus. It's primarily produced in South America and the Canary Islands, but declined in popularity after the introduction of synthetic dyes. However, due to concerns about the safety of synthetic dyes, there has been a recent preference for natural dyes. Carmine, the processed form of Cochineal, is widely used in processed foods. However, it's not acceptable for vegans or those with kosher or halal diets. Cochineal is also used in the dyeing, printing, and paint industries, as well as in cosmetics and medication coatings. Allergens from Cochineal have been detected, causing an IgE-mediated Carmine allergy.
What causes an allergy to Carmine Red Dye?
Allergic reactions are often caused by exposure to Carmine in cosmetics or work-related exposure. Sensitization can lead to allergic reactions from small amounts of Carmine in foods and drinks. It's unclear if topical exposure to Carmine causes sensitivity to ingestion. Allergic reactions are triggered by IgE antibodies, which can cause histamine release and lead to symptoms. However, allergic reactions to Carmine from ingestion are rare due to low levels found in foods and beverages.
When should I order a Carmine Red Dye Allergy IgE Blood Test?
Individuals may order this Carmine Red Dye Allergy Blood Test if they have experienced carmine red dye allergy symptoms.
