General baseline studies in patients with suspected hepatitis C include the following:

  • Complete blood cell count with differential

  • Liver function tests, including levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, albumin, and total and direct bilirubin

  • Calculated glomerular filtration rate (eGFR)
  • Thyroid function studies

  • Screening tests for coinfection with human immunodeficiency virus (HIV) or hepatitis B virus (HBV)

  • Screening for alcohol abuse, drug abuse, or depression

  • Hepatitis B virus (HBV) testing with hepatitis B surface antigen (HBsAg) (to identify coinfection), as well as hepatitis B surface antibody (anti-HBs) and antibody against hepatitis B core antigen (anti-HBc) (for evidence of previous infection)

  • Serum pregnancy testing in women of childbearing age before initiating a treatment regimen that includes ribavirin or that includes direct-acting antiviral agents (DAAs) without ribavirin
