Guidance Released for Medical Providers
Doctors are now being urged to consider increased blood testing for PFAS, also known as “forever chemicals,” as per new guidance from the Centers for Disease Control and Prevention (CDC). The federal agency is advising providers to discuss with their patients potential consumer and environmental exposures to significant levels of PFAS and the possible benefits of blood testing.
Concerns Over PFAS Exposure
Dr. Aaron Bernstein, Director of CDC’s National Center for Environmental Health (NCEH) and the Agency for Toxic Substances and Disease Registry (ATSDR), emphasized the importance of individuals and communities having constructive conversations with their healthcare providers regarding PFAS exposure. He highlighted the widespread exposure to PFAS, with over 90% of the population affected, and the potential health risks associated with these chemicals.
Potential Health Effects and Testing
PFAS are commonly found in various consumer products and have been linked to health issues such as higher cholesterol, cancer, and pregnancy complications. The new CDC guidance suggests that providers take into account an individual’s exposure history and test results from various sources to determine potential ways to reduce future exposures.
Challenges and Future Updates
While blood tests for PFAS can offer insights into exposure levels and provide reassurance to patients, they do not pinpoint the exact source of exposure or directly correlate with specific health conditions. Additionally, the availability and coverage of these tests vary across the country, with costs potentially reaching hundreds of dollars. Bernstein stressed the evolving nature of the science around PFAS and CDC’s commitment to updating information as necessary.
