If a newborn child from a woman with hepatitis c, do hepatitis c rna test within 3 months, then will it show if he is infected with hcv?

Likely but...: 5% of infants born to the mothers with hepatitis c acquire the infection. Viral RNA may be detected intermittently, therefore, a single negative test is not conclusive. False-positive or false-negative result can also occur.

Generally so: If the mother has hepatitis c, performing a hepatitis c RNA test at 3 months and obtaining viral load will identify whether the infant has acquired hepatitis c from the mother. Tests of liver function should be performed the hepatitisc RNA should be repeated at 6-12 months. New medications are available and interferon Alpha can be used to treat infants.
