I took a hepatitis B and C tests and they all came back Non Reactive, at the end of the test it says signal to cut off 0.04 < 1.00. I took the test at Quest and my doctor told me I am fine and don't have HepC , but I said if I didn't then why does it say 0.04 ? I am very nervous Plz help, my doctor keeps saying I am negative and have nothing to worry about. But I am freaking out.
There is no reason whatsoever to "freak out"as your doctor is correct when he tells you that you are "not" infected with HCV
The antibodies screening test uses an algorithm to determine if one has contracted the virus by reflecting a signal to cut -off(s/co) that I have linked the explanation below.
Less than a score of 1 reflects a negative testing for HCV.
Congratulations you do not have the virus.
Best to you
Signal-to-cut–off ratios are calculated by dividing the optical density (OD) value of the sample being tested by the OD value of the assay cut-off for that run. Analysis of enzyme immunoassay and chemiluminescence assay data indicates that s/co ratios can be used to predict supplemental test-positive results. A specific s/co ratio can be identified for each test that would predict a true antibody-positive result (as defined by the results of supplemental testing) ≥95% of the time, regardless of the anti-HCV prevalence or characteristics of the population being tested.
