I don’t see your test result only the signal to cut off ratio that describes the sensitivity of your test.
What was the numerical result of your test? Did the test say positive?
If positive get the test for the hep c virus, the HCV RNA by PCR test. See your doctor for guidance
You seem to have answered your own question . That yes anything > .9 is considered positive for HCV antibodies.
>11 means at sometime you have been exposed to the virus and your physician should now run a HCV/RNA by PCR test to confirm you have Hepatitis C
can anything cause a positive result?
A result of 11 would be cussedness by your body creating antibodies to the hepatitis C virus. This would mean either you were previously exposed to the virus or are currently infected. To find out if you are currently infected you need a second test called the HCV RNA by PCR to see if you have the hep virus in your blood stream.
About 25% of people are able to beat the hep c virus without treatment. Those people and also those who were treated and cured will always test positive for antibodies.
See your doctor and get the HCV RNA test. Then if needed get treated and cured.
