Connecticut DPH generally does not recommend testing your blood for PFAS. There are several reasons why. A PFAS blood test can tell you what your levels are at the time the blood was drawn, but not whether levels in your body are “safe” or “unsafe” or whether your health has been or will be impacted by PFAS. Virtually everyone in the U.S. (and the world) has measurable amounts of PFAS in their body because PFAS chemicals are so widely used in commercial and industrial products. Many of the health issues that have been associated with exposure to PFAS (such as increased cholesterol and decreased thyroid hormone levels) commonly occur in the population even without high levels of PFAS in the blood. These health issues can be caused by many different factors, and there is no way to know or predict if PFAS exposure has or will cause a health problem. It can also be complicated to get a PFAS blood test. It is not a routine test, not many laboratories can analyze blood for PFAS, and it is likely that health insurance would not cover the cost. Finally, a PFAS blood test will not provide information to pinpoint a health problem, nor will it provide information about treatment.
However, if you are concerned about your exposures and wish to have your blood tested for PFAS, you should speak with your physician.
