What is the meaning of: hepatitis C antibody reactive with sígnal to cut-off: 34.00?

What is the meaning of: hepatitis C antibody reactive  with sígnal to cut-off: 34.00?

Exposure, not infect: A positive antibody result against hepatitis c with a high scr most likely represents a true prior exposure to hcv. However, even people with high antibody responses can spontaneously clear the hcv infection. So, everybody with a positive hcv antibody has to get an hcv RNA (viral load) checked to see if they have active infection. Only people with virus are infectious and may need treatment. ...Read more

Hepatitis C (Definition)

Hepatitis c is a virus that replicates (makes copies of itself) in the human liver. People can be infected by exposure to even very small amounts of blood. Over 20 to 40 years it can cause scarring of the liver, and severe scarring is called cirrhosis. People can be tested for exposure with an antibody test. If that is positive, they need a test for the virus itself ...Read more

Male 57, hepatitis C antibody result says reactive 14 with cutoff of 1 . Test performed byy ECLIA . How much chance of false positive. Prognosis?

Male 57, hepatitis C antibody result says reactive 14 with cutoff of 1 . Test performed byy ECLIA . How much chance of false positive. Prognosis?

Check viral load: Even when people have high titer hepatitis c antibody responses, some do not have active infection because their immune system cleared their virus on their own. So the first step is to check a hcv viral load (rna). If the virus is detected in the blood then you do have active infection. At that point you need testing to see how much liver scarring (fibrosis) you have. Work with a specialist. ...Read more

My hepatitis C antibody test is non reactive and my signal c/o ratio is 0.01. Do they use the signal to cut off ratio even if antibody test is negativ?

Yes: The lab uses a signal to cut off ratio (scr) to try to determine whether a signal is "noise" or real. Your scr is very low, and the lab accurately defined this as a negative response. Note, people can have a high scr and still not have chonic hepatitis c infection. ~25% of people will spontaneously clear hcv after infection. They are left with antibodies but the hcv RNA (viral load) is negative. ...Read more

What does it mean if you are positive for hepatitis c antibodies and pcr undetectable. ?

What does it mean if you are positive for hepatitis c antibodies and pcr undetectable.  ?

Hepatitis C: You have gotten hepatitis C at some time but currently do not have active virus in your system. The PCR detects nucleic acid belonging to the virus, demonstrating its presence and the amounts. If you are undetectable do not worry, but keep up with your doctor and ask their opinion. ...Read more

Is a negative hepatitis c antibody test conclusive after 12 weeks from potential exposure?

Is a negative hepatitis c antibody test conclusive after 12 weeks from potential exposure?

I think so: Nobody really knows the rate for late conversions as one never really knows what people are doing that might be risky after the reported exposure is done. If you've having obsessive thoughts about having hepatitis C and a nucleic acid test would reassure you, and you can afford it, then go for it. Best wishes. ...Read more
