Liver Fluke

Addressing the diagnostic challenge of liver fluke

Infection by parasitic liver flukes is associated with a greater risk for cholangiocarcinoma, a lethal cancer of the bile ducts. There is an unmet need for broader availability of diagnostic tests for liver fluke in the U.S.

A critical unmet need

Infection by two liver flukes, Clonorchis sinensis and Opisthorchis viverrini, affects more than 35 million people worldwide, principally in East and Southeast Asia. Because liver fluke infection can persist up to several decades, military service personnel, immigrants, and travelers returning from these areas may continue to experience active infection. Yet diagnostic tests to detect liver fluke infection have not been readily available in the U.S.

New diagnostic alternatives

Kephera provides lab-based testing for liver fluke and is developing new point-of-care assays designed to address unmet diagnostic needs for this infectious disease globally.

      • Transfer the serum or plasma to a plastic tube with screw cap and make sure to close it tightly.
      • The serum and plasma samples should be clear and free from red cells.
      • If EDTA plasma is acceptable for the test, the whole blood can be sent in a tightly closed lavender top (K2 EDTA) tube.
