As worries rise over widespread PFAS (per- and polyfluoroalkyl substances) exposure, the CDC recommends clinicians test patients’ blood for these persistent and dangerous chemicals. Studies show that 98% of Americans may have PFAS in their blood, but the CDC wants to use blood testing to assess the problem and advise healthcare practitioners on risk mitigation.
Understanding ‘Forever Chemicals’
PFAS, commonly known as ‘forever chemicals,’ are notorious for their resistance to breaking down and their ability to persist in the human body for extended periods. The microplastics, prevalent since the 1930s, find their way into the bloodstream, posing a risk of organ damage. PFAS are extensively used in various industries, from water bottle linings to non-stick cookware, contributing to their omnipresence.
The contamination of tap and bottled water with PFAS is a widespread issue, with the chemicals entering water sources through industrial waste, manufacturing, and air pollution. PFAS are associated with health risks, including cancer, liver and thyroid dysfunction, pregnancy complications, and more. Recent research links PFAS exposure to the metastasis of colon cancer cells, emphasizing the urgency of addressing this silent health crisis.
Dr. Aaron Bernstein, director of the CDC’s National Center for Environmental Health, emphasizes that the CDC’s guidance aims to facilitate productive conversations between individuals and healthcare providers. By considering exposure history, water supply testing, and other relevant factors, doctors can assess the necessity of PFAS testing, enabling tailored health interventions and exposure reduction strategies.

Alarming Findings in Tap and Bottled Water
Nearly half of US tap water contains harmful PFAS, according to a major US Geological Survey research. Concentrations were highest in the Great Plains, Great Lakes, Eastern Seaboard, and Central/Southern California. Studies found nanoplastics and PFAS in bottled water, which can cause cancer, infertility, and birth abnormalities.
Communities with elevated PFAS levels in drinking water witness higher cancer rates, increased pregnancy complications, and more cases of low-weight births. The CDC’s emphasis on blood testing reflects a proactive approach to addressing PFAS exposure and its potential health impacts, fostering informed decision-making between patients and healthcare professionals.
