[|AI|]  Hi, thanks for using Chat Doctor The presence of anti HCV means that a person was previously infected with the CHV virus. It is the bodies response to the virus, when a person becomes infected with a virus the body makes antibodies to help fight the infection. Some of these antibodies remain and indicate a previous infection, they do not mean that you are still infected with the virus (have an acute infection). There are slight differences between any labs because of varying machines, techniques and control methods. In addition, they may also be using different units of measurement. For example in some places blood glucose is measured in mg/DL and in others it is measured in MML/l. This means that a normal reading can be less than 110 mg/DL in one set of units and less than 6.1 MML/l in the other set of units. I hope this helps
