Patients seeking care at emergency room at Sahlgrenska University Hospital, Gothenburg, Sweden undergoing ultrasound or computed tomography for suspected gallstone disease, will be asked if they wish to participate in the study. If they agree, a serum sample will be draw for analysis of anti-HAV IgM, HBsAg, anti-HCV, HCV Core antigen and HEV RNA. The proportion of patients with vs. without ultrasound or computed tomography-verified gallstone disease will be evaluated regarding possible ongoing viral hepatitis (i.e. hepatitis A, B, C or E virus infection).
The study aims to investigate possible associations between ongoing viral hepatitis (i.e. hepatitis A, B, C or E virus infection) and ultrasound or computed tomography-verified gallstone disease.
