How Saliva Test Can Diagnose Hepatitis E Infection

A new hepatitis E test that uses saliva rather than blood or stool could be used as an alternative to assess recent or past hepatitis E virus (HEV) infection, a new study reports. The research team''s new saliva test uses a different platform in which antigens are attached to fluorescent beads. These beads can circulate more easily through a liquid, potentially encountering more antibodies to a disease if they''re present in saliva.
