P88 Dietary Antigen Test

The P88 Dietary Antigen Test is one single test combining IgE, IgG, IgG4, and complement (C3d) reactions to 88 of the most common foods found in the diet. The P88 Dietary Antigen Test was the first test on the market to measure and report immune complexes containing C3d. Complement activation is well-defined in the research as not only a cause of inflammation, but one of the strongest causes.

A highly comprehensive test of immune reactions, Precision Point Diagnostics P88 Dietary Antigen Test helps you identify and address food allergies and food sensitivities in patients with chronic illness. Overt IgE-mediated food allergies can lead to hives, anaphylaxis, or digestive issues while delayed food sensitivities (IgG and IgG4) are linked to sinus problems, acne, gas, bloating, fatigue, constipation, autism, irritable bowel syndrome, and even depression.1 Identifying and eliminating food sensitivities can also assist in the healing of intestinal permeability.

Food Sensitivity Symptoms

• Diarrhoea or loose stool
• Constipation
• Gas or bloating
• Heartburn
• Rashes, eczema, or swelling
• Joint pain or inflammation
• Headaches or migraine
• Congestion or runny nose
• Sinus infections
• Acne
• Irritable bowel syndrome
• Fatigue or poor sleep
• Depression
• Poor immune defences
• Malabsorption of vitamins and minerals

The Most Accurate Food Sensitivity Test
Precision Point Diagnostics provides reliable, reproducible semi-quantitative measurement of IgE, total IgG, and IgG4 using an indirect ELISA (enzyme-linked immunosorbent assay). The system is also capable of detecting immune complexes that contain the complement marker C3d.

Other food sensitivity tests may have a weak scientific basis or they may not give the full picture of food reactions. Some tests use live cell analysis, which is not a scientifically accepted sign of true food sensitivity or allergic reaction. Other antibody assays may measure total IgG antibodies only; they could miss food reactions that activate the inflammatory complement cascade. Still, other tests may measure only a specific IgG subclass and miss out on information about our stand-alone IgG4 or combined IgG1, IgG2, & IgG3, which is reported as total IgG in the P88 Dietary Antigen Test.

Better Patient Outcomes
P88 Dietary Antigen Test results can lead to more precise treatment plans and better patient outcomes. Studies show that patients given an elimination diet based on the results of our food allergy and sensitivity testing experienced fewer headaches and less abdominal pain, diarrhoea, constipation, and bloating. Knowing exactly what foods you react to can help to avoid unnecessarily restrictive diets and treatment protocols that inadvertently expose you to food triggers.

The P88 Dietary Antigen Test interpretive report includes more restrictive and less restrictive elimination diets as well as analysis of immune reactions by food groups. The P88 Dietary Antigen Test can spotlight the dietary components interfering with your healing.

Private Blood Draw ($80-$90)
Please note that the test kit comes complete with instructions and a pre-paid courier to the US lab. However, you will need to visit a local blood lab to get a 'private blood draw'. These labs usually charge a fee of $80-$90 for this service. This cost will be additional to the purchase of the test.

Results
Negligible admin costs are added to these test kits and they all come with a pre-paid courier bag (and instructions) for you to conduct and send yourself. The results of the tests get sent directly to us and then we forward them on to you the same day (the lab reports come with very detailed explanations/descriptions of the results). Thereafter, if you would like a consultation (online or in person) to discuss the results, our usual consultation charge would be additional to the functional test.​
