Z.-i gemolizi dar natijai boshiddat tajziya shudani eritrosithoi khun va az tarkibi onho judo gashtani bilirubin (hangomi kamkhunii irsi yo gayriirsi) paydo meshavad.

Odatan, pesh az hama safedii chashm, bad luobpardahoi komi narm, zeri zabon, minbad pust zard meshavad. Darajai zardii pust ba miqdori bilirubini khun vobasta ast. YAke az nishonahoi asosii Z. khorishi pust meboshad. On dar natijai nugi torhoi asabi pustro angezish dodani kislotahoi talkha ba amal meoyad.
