ALEX2 Allergy Test

The ALEX² Allergy Test is one of the most comprehensive allergy blood tests available. It screens for over 280 different allergens—including foods (like milk, eggs, wheat), pollens, dust mites, pet dander, insect venom, molds, and more. Unlike traditional tests, it also detects "cross-reactivity," which means it can identify if your immune system reacts to similar proteins in unrelated substances.

If you're dealing with frequent sneezing, itchy skin, stomach issues, or even unexplained fatigue, this test can reveal what your immune system may be reacting to—so you can make more informed lifestyle and dietary changes.

• What It Measures:
  • Quantitative total IgE, plus specific IgE levels to ~300 allergens, including 120 extracts and ~180 molecular components—food, pollens, pet dander, molds, insect venoms, latex, etc.
• Biomarkers / Scores:
  • Total IgE
  • specific IgE titers in kUA/L for each allergen
  • Mapped molecular components to flag cross-reactivity and risk of severe IgE reactions
• Specimen Required: Blood (serum)
• Turnaround Time: 2–3 weeks
