What the Panel Measures

The SiPhox Allergy Panel measures IgE antibodies to food and environmental allergens and reports Total IgE to help contextualize overall allergy load. Results for each allergen are grouped into clear categories such as negative/uncertain, low, moderate, high, and very high so you can see where sensitization may be clinically meaningful.
Coverage can include up to 295 allergens across 165 sources, spanning:
  • Foods: dairy, eggs, nuts, seafood, fruits, vegetables, grains, spices
  • Environmental triggers: pollen (trees, grasses, weeds), dust mites, molds, pets
  • Other exposures: insect venom, latex, and known cross-reactive proteins

The Testing Process

  1. Purchase – Order your Allergy Panel through SiPhox Health.
  2. At-home sample – Use the EasyDraw arm collector for a simple, comfortable blood collection.
  3. Processing – The lab analyzes your IgE antibody responses across the allergen panel.
  4. Results timeline – Reports are typically available within 5–7 business days.

What You Receive

  • Per-allergen IgE values with category bands from negative/uncertain to very high
  • Total IgE to help gauge overall sensitization
  • Grouped summaries to help spot patterns across allergen families
  • Notes on cross-reactivity to inform next steps and conversations with your clinician

Understanding Different Types of Allergy Testing

Not all allergy-related tests measure the same thing, so results from different test types should not be compared as though they are equivalent. See the AAAAI overview of allergy testing.

IgE testing
IgE blood testing looks for antibodies associated with allergic sensitization. These results can help identify substances that may trigger symptoms such as hives, itching, wheezing, nasal congestion, or other immediate-type allergic reactions. See NIAID’s overview of diagnosing food allergy and the AAAAI explanation of allergy testing.

Patch testing
Patch testing is used to evaluate delayed contact reactions, such as contact dermatitis caused by substances like fragrances, metals, adhesives, or preservatives. It does not measure IgE antibodies and is designed for a different type of immune response. See the AAD page on patch testing.

IgG testing
IgG food testing is different from IgE testing and is often interpreted as a marker of exposure rather than a true allergy. Because of this, IgG results are not interchangeable with IgE allergy testing. See the AAAAI article on IgG food testing.

Why Results May Differ

IgE results can vary across laboratories and over time. Different labs may assess different allergen components within the same category, such as specific proteins within nuts, grasses, or dust mites. Labs may also use different methodologies, allergen panels, and detection thresholds, which can lead to results that do not appear identical.

IgE levels also reflect current sensitization, which means they may change depending on exposure patterns and immune response. As a result, a prior allergy test from another lab may not match exactly, even when both tests are technically accurate. For that reason, allergy results are best interpreted in the context of your symptoms, history, and any prior testing rather than viewed as a perfect one-to-one comparison.

About Our Testing

Our testing is performed in a CLIA- and CAP-accredited laboratory, and the IgE assays we use have been analytically validated, including comparison to standard venous blood draws. While no test is perfect, we are confident in the accuracy and reliability of the results based on these validations.

Why It Matters

Understanding your IgE profile can help identify likely triggers, support more personalized diet and lifestyle decisions, and provide useful information to discuss with your allergist or healthcare provider. It can be a valuable step toward better understanding allergic symptoms and improving daily comfort.
