Full list
of chemicals

Our test screen for the metabolites of 27 widely used everyday chemicals, organised into 5 key groups.

You may come into contact with them in toiletries, cleaning products, food packaging, and household items.

Phthalates

Phthalates are widely used as plasticisers to add flexibility and soften plastic products such as food packaging. Also used to carry fragrance in toiletries.

We screen the metabolites of 5 phthalates

  • Monoethyl phthalate (MEP) – indicates exposure to diethyl phthalate (DEP), a plasticiser and fragrance carrier.
  • Monobutyl phthalate (MBP) – indicates exposure to dibutyl phthalate (DBP), a plasticiser.
  • Mono-2ethylhexyl phthalate (MEHP) – indicates exposure to Di(2-ethylhexyl)phthalate (DEHP), a plasticiser.
  • Mono-(2-rthyl-5-oxohexyl) phthalate (MEOHP) – indicates exposure to Di(2-ethylhexyl)phthalate (DEHP).
  • Monoisobutyl phthalate (MiBP) – indicates exposure to benzoic acid, a preservative and antimicrobial.

Parabens

Parabens are widely used for their preservative and antibacterial properties to keep cosmetics, toiletries, food, and pharmacy products fresh for longer.

We screen for the metabolites of 4 parabens

  • Butylparaben (BuP) and Methylparaben (MeP) indicate exposure to common antimicrobial preservative ingredients.
  • Ethylparaben (EtP) and Propylparaben (PrP) indicate exposure to common preservative ingredients and food additives.

Volatile organic compounds (VOCs)

VOCs are gasses that evaporate easily into air from products, or from combustion processes such as burning. Some have odours, such as paint and glue smells.

We screen for the metabolites of 7 VOCs

  • Methylhippuric acid (2,-3-,4-MHA) indicates exposure to xylene.
  • Phenlyglyoxylic acid (PGO) indicates exposure to styrene.
  • N-acetyl phenyl cysteine (NAP) indicates low exposure to benzene.
  • N-Acetyl (2-Cyanoethyl) cysteine (NACE) indicates exposure to acrylonitrile.
  • N-acetyl (propyl) cysteine (NAPR) indicates exposure to 1-bromopropane.
  • N-Acetyl (3,4-Dihydroxybutyl) cysteine (NABD) indicates exposure to 1, 3 butadiene.
  • 2-hydroxyethyl mercapturic (HEMA) indicates exposure to vinyl chloride and ethylene oxide, both VOCs.

Pesticides & herbicides

Chemicals used to control pests, weeds and diseases in domestic and agricultural settings. Detectable in many types of fresh food and some drinks.

We screen for the metabolites of 5 pesticides & herbicides

  • Glyphosate indicates exposure to the world’s most widely used herbicide chemical ingredient.
  • 2, 4-Dicholorophenoxyacetic (2,4-D) indicates exposure to herbicides.
  • Phenoxybenzoic acid (3-BPA) indicates exposure to pyrethroids, an insecticide.
  • Diethyl phosphate (DEP) indicates exposure to organophosphate pesticide.
  • Atrazine indicates exposure to atrazine, a herbicide.

Bisphenols & other chemicals

A range of chemicals used in plastics, fertilisers, high tempertaure cooking, and explosives.

We screen for the metabolites of 6 everyday chemicals found in food, plastics, and water. 

  • Bisphenol S (BPS) and Bisphenol A (BPA) indicate exposure to bisphenols used to produce plastics and resins.
  • Diphenyl phosphate (DPP) indicates exposure to Triphenyl phosphate (TPHP), a plasticiser.
  • N-acetyl (carbomethyl) cysteine (NAE) indicates exposure to acrylamide, a bi-product of cooking at high temperatures.
  • Perchlorate (PERC) indicates exposure to nitrate fertilisers, or chemicals used in fireworks and explosives.
  • Oxybenzone (OBZ) indicates exposure to this chemical used in sunscreens.
