Where does exposure come from?
CDC says triclosan has been used as an antimicrobial agent in consumer and personal care products, as well as in cleansing preparations in hospitals and other medical settings; its use in consumer soap was banned by FDA, effective 2017.[1] Our marker directory notes it may still be found in some toothpastes, cosmetics, textiles and plastics.[2]
How to test for triclosan at home
Order the Intrinsic Prism test online, collect your samples at home with the kit, and a courier picks them up.[3] Triclosan is one of 38 environmental toxins listed, inside a 133+ marker test. [2]
What can and can't a result tell you?
It can
- Show recent triclosan contact or ingestion.[2]
It can't
- Name the product responsible or prove harm.[2]
A measured level shows exposure. It does not by itself mean the chemical is causing disease.[4] Results are educational and are not a diagnosis; review them with a clinician.
