Easier way to test for PFAS could help detect dangerous levels earlier

A recent study conducted by Michigan State University suggests that an improved method of self-collecting blood samples for testing per- and polyfluoroalkyl substances (PFAS) could lead to early detection of health issues related to these “forever chemicals.” PFAS are persistent chemicals found in various products and environments, with detrimental effects on human health.

The study tested an approach where individuals at risk of PFAS exposure collected their own blood samples using a finger prick. The results showed that this self-collection method was comparable to traditional blood draw methods. The new approach offers convenience and accessibility for individuals concerned about PFAS exposure and enables them to monitor their own blood levels without being part of a research study. However, the authors cautioned that proper self-collection and sensitive analytical methods should be ensured, and further studies are needed before broad adoption in PFAS exposure and health research.
