The Key to Your Patient’s Health

The P88-DIY Dietary Antigen Test is the only report to combine IgE, IgG, IgG4 and complement (C3d) reactions to 88 foods all with the convenience of a finger stick but better, a powerful micro-sampling device! Traditional finger sticks typically have you stick your finger, and then collect on a card or piece of paper. While this is a start, there is not nearly enough blood extracted to run tests with many markers. The P88-DIY looks at 4 ways the body reacts to 88 foods, which means 352 independent tests are run from each sample. The Physician’s Guide to the P88 will help you interpret the results.

Unlike a traditional fingerstick, Precision Point Diagnostics has validated a specific pain-free process, making this test simple for everyone, even small children. The tip uses an “assisted” process to extract more blood. The tip functions like a sponge on the end of a pipette. Using these two concepts together, blood is actively soaked up from a very tiny stick (much smaller than traditional finger sticks), and the rest of the device acts like a pipette as the bulb is released, pulling more blood into the sponge. This radical new technology offers a pain-free way to collect enough specimen to run over 350 reactions to foods. Additional benefits include stability that is far greater than your average “wet” specimen. In fact, the specimen is stable for 21 days. The kits are small, and light, making shipping easier, and your patients can do it themselves, eliminating the need for a phlebotomist. This technique helps patients to have more control of their health by
eliminating many of the barriers that blood tests create. We are excited to offer this groundbreaking technology.

Food Sensitivity Symptoms

  • Diarrhea 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 defenses
  • Malabsorption of vitamins and minerals

The Most Accurate Micro-Sampling 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-DIY Dietary Antigen Test.

Better Patient Outcomes

P88-DIY 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, diarrhea, constipation, and bloating.1 Knowing exactly what foods your patient reacts to can help to avoid unnecessarily restrictive diets and treatment protocols that inadvertently expose your patient to his or her reactive foods.

The P88 Dietary-DIY Antigen Test interpretive report includes more restrictive and less restrictive elimination diets as well as analysis of immune reactions by food groups. This customized report not only helps the clinician use at-a-glance results in clinical practice but also better ensures patient compliance (see sample report).

The P88-DIY Dietary Antigen Test can spotlight the dietary components interfering with your patients’ healing. It is the missing piece of the puzzle and can lead to the resolution of previously resistant health problems.
