PCSIG Webinar On Demand

Advancing the collection and analysis of PFAS in blood

PCSIG PFAS in Blood Wide.png

Recently, the National academies of Sciences, Engineering and Medicine (NASEM) has recommended that people test their water and blood for per- and polyfluorinated substances (PFAS). This is a change from the past direction. The blood test places people into one of three categories based on the sum of seven pertinent PFAS. This sum then informs clinical care depending on the PFAS levels.

Traditionally, PFAS tests have been conducted with serum. This is true of the CDC studies and most academic cohorts. Only recently has technology developed to a point where both a volumetric sampling device and highly sensitive instrumentation can come together to assist the analytical challenge of a remote PFAS blood test. Equally important are the suite of isotopically labeled standards that are spiked into every sample to aid in quantitation. This approach is known as isotope dilution and it is considered the gold-standard of quantitation.

This talk aims to educate the viewer on this new approach for PFAS testing, and will be of particular interest to:

  • Health and safety officers

  • First responders

  • Academic researchers

  • Curious citizens​​​​​​​

What you will learn

  • The vast majority of people have PFAS in their blood. It is a matter of what analytes and how much.

  • Attendees will learn about isotope dilution quantitation.

  • Attendees will learn about linear and branched PFAS isomers.

  • The basics of LC-MS/MS will be presented.

  • The talk will also include discussions on half-lives and bioaccumulation.
