Bisphenol A (BPA)
Bisphenol A (BPA) is an industrial chemical used in polycarbonate plastics, in the inner coatings of food cans and formerly in thermal paper (till receipts). It is taken up mainly through food and to a lesser extent through the skin.
How bisphenol A acts in the body
BPA resembles the hormone oestrogen in structure and can bind to its receptors; it is therefore classed as an endocrine-active substance. In 2023 the European Food Safety Authority (EFSA) lowered the tolerable daily intake very considerably; since 2025, BPA in food contact materials is being phased out in the EU. The body breaks BPA down within hours and excretes it.
BPA undetectable or low – what does it mean?
An undetectable or low value indicates low current intake. Because BPA is excreted quickly, the measurement describes exposure over the last few days.
Raised BPA – what does it mean?
A raised value shows currently higher intake, for example from canned food, heated plastic containers or occupational sources. Since the value reflects the last few days, sources can be narrowed down well and a follow-up measurement shows whether anything has changed.
The interpretation is given in your report.
