The half-life of PFHxS in adult blood serum is 5.3 years (4.7 years for women and 7.4 years for men). [10] The half-life of PFASs in human blood generally decreases with decreasing backbone (CF 2) length. However, PFHxS is an unusual exception in that its half-life is greater than both longer and shorter chain equivalents such as PFOS or PFBS.

In humans, PFOSA has been detected in sub- to low-parts per billion levels; [14] for example, in 1999–2000 US serum samples, the 95th percentile (or value where only 5% of the population was higher) was 1.4 parts per billion [15] while in 2003–2004 the 95th percentile fell to 0.2 parts per billion.
