Hepatitis A generally looks for serum IgM hepatitis A virus antibodies (anti-HAV IgM); hepatitis E generally looks for anti-hepatitis E virus IgM antibodies (anti-HEV IgM) and anti-hepatitis E virus IgG antibodies (anti-HEV IgG). Viral hepatitis A is usually more prevalent in the fall and winter, with a higher incidence in preschool children. During screening, enzyme-linked immunosorbent assay is usually applied to detect the presence of IgM hepatitis A virus antibody (anti-HAV IgM) in serum, which usually appears in the early stage of hepatitis A and is a specific indicator. Viral hepatitis E is an infectious disease transmitted mainly through the digestive tract, with a high incidence in young adults and middle-aged and elderly people. Patients are usually examined for anti-HEV IgM and anti-HEV IgG in serum, with anti-HEV IgM occurring in the early stages of the disease and anti-HEV IgG having a high titer in the acute phase and decreasing significantly in the recovery phase. It is recommended that the patient consult a professional doctor according to their own test results, and the doctor will make a specific judgment based on the clinical symptoms.
