Underestimation of the results of PFAS analyses in Wallonia: what are the consequences for the citizens concerned?
The recent error in the PFAS blood test results has far-reaching consequences for the affected residents of Chièvres, Ronquières and Nandrin. Due to a technical problem in the preservation of blood samples – specifically during the freezing of the blood samples – the PFAS levels in the analyses were underestimated, with fluctuations from 30% to 90%.
The recent error in PFAS blood test results has far-reaching consequences for the affected residents of Chièvres, Ronquières and Nandrin. Due to a technical problem in the preservation of blood samples – specifically during the freezing of the blood samples – PFAS levels were underestimated in the analyses, with fluctuations from 30% to 90%. This error means that the severity of PFAS exposure, which can pose significant health risks, was initially incompletely conveyed.
Health consequences and care pathway
PFAS levels below 2 micrograms per liter are considered harmless by experts, even if the results were doubled. However, for people with results between 2 and 20 micrograms per liter, the underestimation could mean they may be above 20 micrograms per liter, a level for which medical follow-up is recommended. Those who were already above this threshold are therefore considered to be even more exposed than previously thought, reinforcing the need for a thorough care pathway.
Impact on trust and next steps
It is understandable that this situation raises concerns and questions among the affected citizens. The region is planning meetings with the residents concerned and is offering psychological support through the ISSep. Furthermore, new blood tests are being organised to ensure more accurate results. This situation highlights the importance of transparency and trust in public health measures, where a consistent care pathway is essential to monitor and manage further health problems.
Long-term solutions and responsibilities
Yves Coppieters has indicated that the fault lies in technical processes between ISSep and the laboratory, without direct political liability. Nevertheless, this issue will probably lead to a review of the protocols for storing and testing blood samples to prevent future errors and restore public confidence in public health services.
