Allergy & Sensitivity

P88 Dietary Antigen Test (Serum)

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.

Precision Dietary SIgA (Saliva)

Precision Dietary SIgA measures salivary levels of secretory IgA (SIgA) antibodies to 88 different foods. Immunoglobulin A is the most abundant antibody isotype in the mucosal immune system, which lines the mouth, gut, lungs, and genitourinary tract. SIgA is your patients’ first line of defense at the mucosal surface, where it binds and neutralizes pathogens, allergens, and toxins.

Around the world, allergic rhinitis affects between 10 – 30% of the population. This serum test can be used in addition to, or as an alternative to, traditional skin prick tests.

Which medications should I avoid before testing?

Precision Allergy 88 & Precision Airborne Allergy

Steroids should be discontinued 72 hours before testing

Some examples of steroids include:

  • triamcinolone
  • cortisone
  • prednisone
  • methylprednisolone.

Intestinal Barrier Assessment:

  1. Zonulin- No interactions
  2. LPS

Antibiotics will not affect the test, but better to finish a course of antibiotics first to see how it alters LPS response. If patient is on long term on-going antibiotics, can be done at same time, but expect that LPS immune response would be higher if not on antibiotics

  1. Histamine

Avoid anti-histamines following medications for at least 24 hours

Some anti-histamines include:

  • Brompheniramine (Dimetane)
  • Cetirizine (Zyrtec)
  • Chlorpheniramine (Chlor-Trimeton)
  • Clemastine (Tavist)
  • Diphenhydramine (Benadryl)
  • Fexofenadine (Allegra)
  • Loratadine (Alavert, Claritin)
  1. DAO
  • Tagamet and SSRIs will lower DAO

Adrenal Stress Test

Avoid Steroids for 72 hours

Do not take DHEA on morning of test

Thyroid profile

Do not take thyroid medications on morning of test

Oxidative Stress Test

No medication interactions

I am a Patient, can I order a Test directly through your Lab?

Laboratory regulations require that all of our Tests be ordered by a Healthcare Provider. If you are interested in finding a physician in your area that offers our testing please reach out to

Who can order testing from your laboratory?

As a CLIA certified laboratory, we are required to work with healthcare providers that are licensed and authorized by their states to order and interpret diagnostic medical testing.

Can you ship a test kit directly to my patient?

Yes we can! We will ship to any patient within the USA at no additional charge. You can dropship a kit directly through our portal. If your patient resides outside the USA, shipping charges to the patient will apply. You will need to contact us for estimated shipping charges.

How long does it take to receive results?

At Precision Point Diagnostics rapid, accurate results are our #1 priority. Turnaround time varies from 7 – 14 business days for most tests ordered. Due to the current pandemic, turnaround time may extend due to supply chain interruptions.

What are considered normal reference ranges?

Every lab is required to develop its own reference ranges. For this reason, you should not expect ranges to be the same from lab to lab. At Precision, we look at the values over the hundreds of thousands of specimens we have run and then look at distributions. In general, the top 5% is determined high, and then the next 25% is moderate, and then the next 25% is lower. However, when there is epidemiologic evidence that the population, in general, has more difficulty with a food, such as wheat or dairy, we will consider % reactivity in populations in general, and consider research and data, alongside our distributions to create a range. 

What credentials are required to test with your laboratory?

Each state has different regulations which govern the scope of practice for the practitioner. It is the responsibility of the practitioner to work within the rules and guidelines of the state. You may check with your state board of health for clarification about the specific restrictions that your state may have with regard to laboratory testing. Precision Point Diagnostics accepts authorization from Medical Doctors (MD), Osteopathic Doctors (DO), Chiropractors (DC), Naturopathic Doctors (ND), Doctors of Philosophy in Psychology, Biochemistry, Toxicology, and Nursing (PhD), Doctors of Oriental Medicine (DOM), Licensed Acupuncturist (Lac), Physicians Assistants (PA), Nurse Practitioners (ARNP), Nurse Midwives (CNM), Certified Nutritionists (CCN), and Registered Dietitians (RD). All ordering Health Professionals must have an NPI Number to participate in our testing services.

Do you accept testing from anywhere?

Precision Point does not accept business from New York State. We do accept all other states as well as international business. For more information on International ordering contact

Can Babies complete the Precision Allergy 88 Test?

The immune system is more mature by 9 or 12 months, but if for example there is a baby who is having terrible eczema, or gut pain, or other issues that you think are food-related, if the symptoms are bad enough, you should still consider testing.
