We are a Philippine-based company with the most comprehensive nutrient-focused clinical diagnostics in Asia. We bring the extensive experience of industry pioneers and experts from Europe to bring intracellular nutrient diagnostics in the region.

We utilize advanced technologies and validated test methods performed by highly competent and internationally trained staff. Our method development and staff trainings were proudly supervised and benchmarked by the European Laboratory of Nutrients (ELN).

Pioneer of
Nutritional Testing
in Europe.


We specialize in metabolomics—the study of the individual chemical fingerprints created during metabolic and cellular processes. We examine intracellular health instead of just standard organ-based testing. Our nutrient, metabolic, and environmental tests provide clinicians with diagnostic measures that are indicators of cellular health. These include nutritional deficiencies, toxin exposures, and inflammation markers.

Micronutrient and Macronutrient Testing

  • Quantitative measurement of vitamins, minerals, cofactors, antioxidants, amino acids, fatty acids, and other nutrients
  • Identification of micronutrient deficiencies and toxicities at the intracellular level

Testing for Heavy Metals and Toxic Elements

  • Detection of toxicities acquired from common environmental toxins and pollutants including heavy metals such as mercury, lead, cadmium and arsenic

Organic Acids Testing

  • Measurement of the by-products of metabolism (organic acids) which can be used as markers to analyze nutrient absorption and utilization, detoxification, neurotransmitter function, and gut bacterial overgrowth

Food Intolerances or Food Sensitivity Test (IgG)

  • Assessment of IgG antibodies produced by the immune system which can be triggered by certain types of food; delayed IgG food intolerance is often undetected and can cause inflammatory processes

Food and Inhalant Allergies (IgE)

  • Quantitative detection of allergen-specific IgE antibodies from common food and inhalant allergens causing immediate allergic reaction


  • Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
  • Liquid Chromatography with Tandem Mass Spectrometry (LC-MS/MS)
  • Gas Chromatography (GC)
  • High Pressure Liquid Chromatography (HPLC)
  • Microplate Reader – UV/VIS, Fluorescence, Luminescence
  • Clinical Chemistry Analyzer (CA)
