A new report from the government has found there is “no clinical benefit” to having a blood test for Pfas after the so-called “forever chemicals” were found in local water supplies in the Blue Mountains.A new report from the government has found there is “no clinical benefit” to having a blood test for Pfas after the so-called “forever chemicals” were found in local water supplies in the Blue Mountains.

The panel included science and health experts in cancer, hormone and heart health, epidemiology, pathology, primary care, public health and risk communication.The panel included science and health experts in cancer, hormone and heart health, epidemiology, pathology, primary care, public health and risk communication.
They found, based on the substantial research related to Pfas already undertaken, “the health effects of Pfas appear to be small”.They found, based on the substantial research related to Pfas already undertaken, “the health effects of Pfas appear to be small”.

Pfas are a class of manufactured chemicals used to make products that resist heat, stains, grease and water – sometimes called “forever chemicals” as they are difficult to destroy and can remain in soil, groundwater and travel long distances.Pfas are a class of manufactured chemicals used to make products that resist heat, stains, grease and water – sometimes called “forever chemicals” as they are difficult to destroy and can remain in soil, groundwater and travel long distances.
The report acknowledged that studies have reported an association with some health effects, but noted the findings are inconsistent across different studies with “limited evidence of a dose-response relationship”.The report acknowledged that studies have reported an association with some health effects, but noted the findings are inconsistent across different studies with “limited evidence of a dose-response relationship”.
The report also found that “while clinical testing for Pfas is commercially available, the current scientific evidence indicates that there is there is no clinical benefit for an individual to have a blood test for Pfas”.The report also found that “while clinical testing for Pfas is commercially available, the current scientific evidence indicates that there is there is no clinical benefit for an individual to have a blood test for Pfas”.
The authors stated Pfas blood tests were unlikely to guide medical care “because Pfas will be detected in most people, there are many different Pfas types and blood levels do not predict any current or future health outcomes”.The authors stated Pfas blood tests were unlikely to guide medical care “because Pfas will be detected in most people, there are many different Pfas types and blood levels do not predict any current or future health outcomes”.

The report recommended that “should a health care provider order a blood test for Pfas for a patient, the health care provider should provide clear contextual information about the test and its limitations to the patient, to manage expectations and avoid misinterpretation”.The report recommended that “should a health care provider order a blood test for Pfas for a patient, the health care provider should provide clear contextual information about the test and its limitations to the patient, to manage expectations and avoid misinterpretation”.
The authors also suggest doctors can support patients concerned with their serum PFAS levels by engaging in usual preventative health interventions, “as many of the health conditions potentially associated with PFAS are common in the community and are associated with well-established risk factors”.The authors also suggest doctors can support patients concerned with their serum PFAS levels by engaging in usual preventative health interventions, “as many of the health conditions potentially associated with PFAS are common in the community and are associated with well-established risk factors”.
The panel acknowledged their recommendation differs from the National Academies of Science Engineering and Medicine (NASEM), an independent institution in the United States, whose guidance documents recommended individual blood testing and the use of blood levels to inform clinical care.The panel acknowledged their recommendation differs from the National Academies of Science Engineering and Medicine (NASEM), an independent institution in the United States, whose guidance documents recommended individual blood testing and the use of blood levels to inform clinical care.
They also noted the Agency for Toxic Substances and Disease Registry, overseen by the US Centers for Disease Control and Prevention, gives advice to clinicians on managing and evaluating Pfas exposure and has not adopted NASEM’s recommendations on individual blood testing and health-based screening based on Pfas blood levels.They also noted the Agency for Toxic Substances and Disease Registry, overseen by the US Centers for Disease Control and Prevention, gives advice to clinicians on managing and evaluating Pfas exposure and has not adopted NASEM’s recommendations on individual blood testing and health-based screening based on Pfas blood levels.

Dee said they wanted to see how their blood test compared with the areas of Williamtown, Oakey and Katherine, which were contaminated with Pfas due to firefighting activities on nearby defence force bases.Dee said they wanted to see how their blood test compared with the areas of Williamtown, Oakey and Katherine, which were contaminated with Pfas due to firefighting activities on nearby defence force bases.
“If you look at the average blood test level of people in the Blue Mountains, we are two to three times higher than the average Pfas levels in those defence communities that have been compensated by the federal government,” Dee said.“If you look at the average blood test level of people in the Blue Mountains, we are two to three times higher than the average Pfas levels in those defence communities that have been compensated by the federal government,” Dee said.
Dee said what concerned the community was how many of them with high Pfas levels in their blood have also had health issues that have been known to be associated with Pfas, including cancer.Dee said what concerned the community was how many of them with high Pfas levels in their blood have also had health issues that have been known to be associated with Pfas, including cancer.

“The findings of this report clearly are more to do with reducing the legal liability of Sydney Water than actually looking after the health of people in the Blue Mountains,” Dee said.“The findings of this report clearly are more to do with reducing the legal liability of Sydney Water than actually looking after the health of people in the Blue Mountains,” Dee said.

“There is considerable concern, particularly in the Blue Mountains community, about exposure to Pfas through drinking water, and NSW Health takes these concerns very seriously,” Chant said.“There is considerable concern, particularly in the Blue Mountains community, about exposure to Pfas through drinking water, and NSW Health takes these concerns very seriously,” Chant said.
“NSW Health will continue to support local clinicians with information for GPs who may be managing patients with concerns about Pfas exposure including evidence about potential adverse health effects, counselling patients, the utility of blood tests for Pfas and the role of further investigations.”“NSW Health will continue to support local clinicians with information for GPs who may be managing patients with concerns about Pfas exposure including evidence about potential adverse health effects, counselling patients, the utility of blood tests for Pfas and the role of further investigations.”
