Can you be positive for hepatitis C for 20 years and not have a positive blood test?

It would be highly unlikely not to have a positive hepititis C blood test if you had had hepititis for 20 years. (However, just to be clear, standard types of blood test, such as "full blood counts" do not test for Hep C. The only blood test that does test for Hep C is the Hep C blood test).
Although it would depend slightly on how often you were having the blood test done; there is a very small chance of a test being postitive when the patient is negative, and the same change of the test being negative when the person is positive. If you just had the one test done, the result is mainly accurate, however without another 1 or 2 done in subsequent years is difficult to conculsively establish that the first one was utterly accurate.
For example, if you had a sequence of (let P=positive and N=negative)
PNN, it would be more likely that you were not carrying hep C than carrying Hep C.
If the sequence was NPN, it's still more likely that you're not carrying hep C, although you may be asked to have another test, just to make sure.
Whereas NNP, you're GP may ask you to get the test redone, just to be sure.
