In addition to a fungal culture and stain, other tests may be ordered to help diagnose a fungal infection in the liver or biliary system, such as blood tests or imaging studies (such as an ultrasound or CT scan). Treatment for fungal infections of the liver or biliary system may involve antifungal medications and, in some cases, surgery to remove infected tissue or drain abscesses. It is important to follow all instructions from the healthcare provider to ensure the best possible outcome.
