In-house RT-PCR detection of hepatitis A virus in human plasma pools used for the manufacture of medicinal products.

Hepatitis A virus (HAV) is the most frequent cause of viral hepatitis worldwide and is transmitted through the fecal-oral route. However, HAV can also be transmitted by blood-derived products. This is due to the fact that viremia occurs during the asymptomatic phase of HAV infection, enabling infected blood or plasma donations to occur.
