Perfluorooctane Sulfonic Acid (PFOS) details
What Perfluorooctane Sulfonic Acid (PFOS) shows
Perfluorooctane sulfonic acid (PFOS) is one of the best-known PFAS chemicals, once widely used in stain- and water-repellent coatings and firefighting foams. It has been largely phased out in the US but persists in the environment. This test measures PFOS in your serum to help estimate your exposure from sources such as drinking water, food and household dust. Branched forms may be reported separately. PFAS leave the body slowly, so the level mainly reflects exposure over months to years. A higher result means more exposure; research links higher PFAS levels with effects such as raised cholesterol, but a result cannot show that it caused a symptom. It is read alongside the other PFAS on the panel.
Tests that include Perfluorooctane Sulfonic Acid (PFOS)
Per- and poly- fluorinated alkyl substances (PFAS) are man-made chemicals that have been used in industry and consumer products since the 1940s. Commonly referred to as “forever chemicals,” PFAS do not break down easily in the environment. While the science around the potential health impacts of PFAS exposure is still emerging, evidence suggests that high PFAS exposure is associated with certain health conditions. People are most likely exposed to these chemicals by consuming PFAS-contaminated water or food, using products made with PFAS, or breathing contaminated air.
- N-Methylperfluorooctane Sulfonamidoacetic Acid (N-MeFOSAA) Measures N-MeFOSAA, a PFAS forever chemical, in your blood to help assess exposure to this group of persistent industrial compounds.
- Perfluorodecanoic Acid (PFDA) Measures perfluorodecanoic acid (PFDA), a long-chain 'forever chemical,' in your blood to help gauge your past and ongoing exposure to PFAS compounds.
- Perfluorohexanesulfonic Acid (PFHxS) Measures perfluorohexanesulfonic acid (PFHxS), a persistent 'forever chemical,' in your blood to help gauge your exposure to PFAS from water, products and the environment.
- Perfluoromethylheptane Sulfonic Acid Isomers (Sm-PFOS) Measures the branched forms of PFOS (Sm-PFOS) in your blood, part of assessing your overall exposure to PFOS and other 'forever chemicals.'
- Perfluorononanoic Acid (PFNA) Measures perfluorononanoic acid (PFNA), a persistent 'forever chemical,' in your blood to help gauge your exposure to PFAS compounds from the environment.
- Perfluorooctane Sulfonic Acid (PFOS) Measures perfluorooctane sulfonic acid (PFOS), one of the most studied 'forever chemicals,' in your blood to help gauge your long-term exposure to PFAS.
- Perfluorooctanoic Acid Isomers (Sb-PFOA) Measures the branched forms of PFOA (Sb-PFOA) in your blood, part of assessing your overall exposure to PFOA and other 'forever chemicals.'
- Perfluorooctanoic Acid (PFOA) Measures perfluorooctanoic acid (PFOA), a well-studied 'forever chemical' once used in non-stick coatings, in your blood to help gauge your PFAS exposure.
- Perfluoroundecanoic Acid (PFUnDA) Measures perfluoroundecanoic acid (PFUnDA), a long-chain 'forever chemical,' in your blood to help gauge your exposure to PFAS compounds.
