<unk>  E cannot be distinguished from other types of<unk>  based on clinical manifestations alone.  Although blood markers of liver injury, such as elevated aminotransferases may be identified, definitive diagnosis of<unk>  E is done by serologic tests.  Viral load and antibody titers will vary according to the stage of the infection: during the incubation period, the virus may be detected in blood and in stool; during the clinical manifestation of the disease, ALT and AST are often elevated, the virus may be detected in stool, and anti-HEV IgM and anti-HEV IgG may be detected; during the recovery phase, IgM levels decrease, being detected during 3 to 12 months, while IgG levels may remain detectable throughout many years.  Amplification techniques are also useful for detecting HEV infection, viral genotyping, and identifying specific genomic sequences.
