Your doctor that ordered this can give you a definitive answer.
My best answer is as a lay person who is not a medical worker of any kind and as a patient who was formerly infected with hep c. This is what I was able to find from a search of the internet:
Your test result was 0.1
The scale of the test is 0.0 - 0.9. s/co means signal to cutoff ratio it has to do with the sensitivity of the test the 0.0-0.9 s/co is not your result.
Results of below 0.8 are negative, 0.8 - 0.9 are indeterminate, and above 0.9 are positive.
Your result of 0.1 is a negative result but for a more informed answer you should ask your doctor.
