Ms analysis of 96 inflammatory and anti-inflammatory protein panels suggests that changes remain in inflammatory biomarkers and stress-induced biomarkers for more than 40 days after suffering from COVID-19.
Specifically, it is said that the effects of the following six biomarkers remain after the disease.

    peroxiredoxin 3 (PRDX3)
    carbamoyl phosphate synthase (CPS1)
    N-Myc downstream regulated gene 1 (NDRG1)
    Collagen triple helix repeat containing 1 (CTHRC1)
    Cystatin C (CYTC)
    Progranulin (GRN)
