Serum PFOA Calculator

Serum PFOA Calculator for Adults

For other PFAS chemicals and updated default values for ongoing exposures, see our new PFAS serum calculator

Please enter the following values, then click on the "submit" button:

1. How much PFOA was in your blood sample? (2 is a typical value for an adult with no PFOA in his or her water.)
Starting serum PFOA concentration (μg/L, ng/mL, or ppb)

2. How much PFOA is in your drinking water? Enter 0 if you're drinking only bottled water, carbon-filtered water, or water treated by reverse osmosis.
Water PFOA concentration for ongoing consumption (ng/L, or ppt)

All content is for informational purposes only and is not intended to serve as a substitute for the consultation, diagnosis, and/or medical treatment of a qualified physician or healthcare provider. Calculations are based on average values for adults; individual results may vary due to individual differences in water consumption, PFOA excretion, and exposures from other sources. Model assumptions and defaults: one compartment pharmacokinetic model with 2.3 year serum half-life (Bartell et al., 2010); 114 steady-state serum:water concentration ratio (Hoffman et al., 2011); 2.08 ng/mL serum contribution from other ongoing exposure sources (CDC, 2015).
