The presence of "Anti-HCV antibodies class IgG" indicates that your daughter in law is or was infected with Hepatitis C-virus (HCV). Unfortunately, a HCV-infection can be overcome in only 30% of the cases. In those cases, the HCV-infection will be cleaned completely from the body with no consequences and permanent immunity from the disease thereafter. If the antibodies are the only evidence the doctors found, they could suggest that she has already overcome the infection and has developed permanent immunity.
In the remaining 70% of these cases, an acute HCV-infection progresses into chronic hepatitis with final consequences such as hepatic cirrhosis or hepatic cancer. If her other laboratory reports indicate positive findings such as increased enzymes (AST, ALT, LDH) or increased bilirubin, these tests could indicate a chronic HCV-infection. Your son and the baby must be tested for HCV-infection as soon as possible because HCV-infection is transmitted in the same way as Hepatitis B and HIV/AIDS: through unprotected sex, using contaminated needle for drug injection, open wound contact with contaminated blood, from mother to fetus during pregnancy, etc.
