Neopterin levels in individuals with and without PCS. (A) Absolute neopterin values for asymptomatic (group 1) and symptomatic COVID-19 courses without PCS (group 2), as well as with PCS (groups 3, 4 and 5) at the time of the seropositive blood donation (0 M). Neopterin levels higher than 11 nmol/L (dashed line) are considered to be enhanced. (B) Relative change of neopterin levels in comparison to pre-pandemic blood donations in 2019
