Hi we here are not medical professionals I am not familiar with antibody testing as I was diagnosed with hep c before there was antibody testing so never had an antibody test. What I can read is s/co means signal to cut off ratio so basically the scale of the test is 0.0 to .09 I am guessing anything greater than .9 is a maybe positive with greater numbers above 0.9 meaning more likely.
Your test result again just guessing is Neg 0.9 so negative at 0.9 to me negative means negative but fo ra by far better understanding than I can give you should ask your doctor.
Just to add even a positive test does not mean a person has hep c. They may have only been exposed at some point but not be currently infected. The only way to confirm a current infection is with a test for the actual virus not just the antibodies to the virus. Antibodies are not the virus they are made by the persons body when it comes into contact with the virus. Antibodies are made by people in response to a virus.
The name of the test for the hep c virus is HCV RNA by PCR test. They screen for hep c first with the antibody test and if that is positive then they use the HCV RNA test to confirm current infection.
But anyway you will need to discuss your result with your doctor but my guess is it is negative and you don't have hep c but ask your doctor to be sure.
