Carmine Red Dye IgE Allergy Blood Test

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. Allergy symptoms vary depending on the individual, ranging from mild to severe reactions. Most food-related symptoms occur within two hours of ingestion but frequently begin within minutes. In addition, the response can be delayed by four to six hours or even longer in some rare cases.

An allergic reaction may affect the skin, intestinal lining, and air pathways. Individuals with a carmine red dye allergy may experience one or more of the following symptoms:

• Tingling sensation near or around the mouth
• Swelling
• Abdominal discomfort
• Nausea or vomiting
• Diarrhea
• Itching or hives
• Congestion
• Difficulty breathing, swallowing, or wheezing
• Lightheadedness

In some cases, a severe, possibly life-threatening allergic reaction known as anaphylaxis may occur. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis may include:

• Rapid or increased heart rate
• Swollen throat or lump making it difficult to breathe
• Low blood pressure
• Extreme dizziness or loss of consciousness
