A blood test can measure PFAS in your blood, but this is not a test routinely done in a doctor's office. While it is possible to get your blood tested for PFAS, test results will only tell you how much PFAS is present in your blood and not whether your health has been, or will be, affected by PFAS. At this time, the scientific understanding of PFAS is not sufficient to determine health risks based on the level of PFAS in a person's blood. Most people in the U.S. have measurable amounts of PFAS in their body because PFAS are commonly used in many consumer and industrial products.
If you have specific health concerns or would like to have your blood tested, please talk with your doctor. Some of the health effects possibly linked to PFAS exposure, like high cholesterol, can be checked as part of your annual physical. It is important to have regular check-ups and screenings.
Additional information on blood testing can be found on the Agency for Toxic Substances and Disease Registry's (ATSDR) PFAS Blood Testing page. You can also read their Talking to Your Doctor about Exposure to PFAS fact sheet. The ATSDR is a federal public health agency of the U.S. Department of Health and Human Services.
