Clonorchis sinensis IgG

Clonorchis is a liver fluke parasite that can also infect the gallbladder and bile duct. Humans may be infected by eating raw or undercooked fish. While often symptomless, long-term infections can result in severe illness. Detection of specific IgM antibodies provides evidence of a current or recent infection. A demonstration of specific IgG is evidence of past infection.
