ALEX³ combines state-of-the-art nanotechnology with the comprehensive allergy testing panel — built on over 1 million real-world test results.
Simultaneously tests 300 allergens, including of 218 molecular components and 82 extracts.
More molecular allergens, wider coverage, pinpoint precision.
Provides quantitative measurement for specific IgE (sIgE) and quantitative total IgE (tIgE).
Integrates a powerful CCD blocker to neutralize up to 30% false-positive results caused by Cross-reactive Carbohydrate Determinants (CCD).
Requires only 100–200 µL of serum — ideal for infants and children (fingertip prick available), with no need to discontinue antihistamines.
Accurately diagnoses severe risks using markers like Api g 7 (celery defensin, responsible for severe Mugwort-Celery Syndrome), Tri a 36 & Tri a 37 (wheat allergens indicating true pediatric wheat allergy and high-risk anaphylaxis), and alpha-Gal (the carbohydrate marker for delayed red meat allergy/tick-bite syndrome).
Includes freshwater shrimp specific IgE component allergens (Mac r 1 & Mac r 2), salmon collagen (Sal s 6), and vital tree nut markers like Pru du 6 (almond) and Mac i 1.0101 (macadamia).
Covers molds, yeast (including Mala s 13 for severe atopic dermatitis), mites, pets, farm animals, and venom — a complete environmental sensitization picture.
ALEX3 clearly differentiates between high-risk, heat-stable allergens (such as seed storage proteins that cause systemic anaphylaxis) and low-risk, heat-labile allergens (like PR-10 proteins that cause mild oral symptoms). This prevents unnecessary dietary restrictions and patient anxiety.
The test is bundled with interpretation system built on clinical literature and test results. It instantly translates complex IgE profiles into actionable therapy and dietary recommendations.
By distinguishing between genuine sensitization and cross-sensitization effectively, doctors can prescribe Allergen-Specific Immunotherapy (AIT) with precision, avoiding costly and ineffective treatments.
Cver 1 million tests worldwide
Certified as a CE-IVD medical device
We are Hong Kong’s premier diagnostic testing facility. We partner with doctors, medical specialists, hospitals, and corporate healthcare networks to deliver state-of-the-art diagnostic insights.
Our allergy testing division brings particular depth to this mission: from varieties of IgE sensitisation test to gut microbiome analysis, we provide clinicians and patients with the clarity needed to make confident, evidence-based decisions.
