Clonorchis sinensis IgM

Clonorchis is a liver fluke parasite that can also infect the gallbladder and bile duct. Humans can become infected by eating raw or undercooked fish containing this parasite. While most persons do not show symptoms, long-lasting infections can result in serious illness. Detection of specific IgM antibodies can provide evidence of a current or recent infection. A demonstration of specific IgG is evidence of past infection.
