Indications

Overview

The majority of adverse immune reactions to foods classified as type II, III, or IV with delayed system onset, are mediated by IgG and are termed food sensitivities. It has been estimated that 90% of immune reactions to foods are non-IgE or delayed symptom onset food allergies. A single blood test can identify patient’s food sensitivities. Recommended treatments for food sensitivities is elimination of reactive foods from the diet for a period of 3 to 4 months followed by reintroduction and rotation. This test, tests for 115 foods.

Recommended for

The test is perfect for anyone who tends to cook their own food or eats the same thing on a routine basis. The test covers all foods commonly known to cause allergies, including milk, eggs, nuts, fish, shellfish, soybeans, and wheat. Consider this test if you:

• Tend to eat the same foods on a daily basis
• Rarely eat out or at restaurants
• Already tested using Bloodprint Complete or Bloodprint Premium
• Want to continuously monitor inflammatory foods and adjust your diet

Signs of Food Allergies

Signs of food sensitivity or intolerance typically occur within hours to days after eating a specific type of food. Food allergies may show up immediately or within minutes to hours of eating. The signs and symptoms vary depending on the food allergy as well as the individual.

• Skin rash or hives
• Tingly or itchy feeling inside the mouth
• Swelling of lips, tongue, throat, and face
• Stomach cramps or pain
• Diarrhea or flatulence
• Indigestion or gas
• Nausea or vomiting
• Difficulty swallowing or breathing
• Dizziness or fainting
