higher alps after surgery

We thought all was going well for my mom she went Tuesday to get staples out and drainage tube out they said she looked really good. Sent her for routine blood work and now the bad her alps are over 2000 it was 1400 before operation she was yellow and itching then. now shes not itching and not yellow at all but the alps are even higher?anyone have this problem? they sent her for ct scan and more blood work just to make sure it wasn’t a mistake now the waiting.thanks
