Ms Nicola Perry:

That would not be the normal clinical process. The test for hepatitis C is a two-step test. It is fairly straightforward. I will note that I am not a clinician and there are no clinicians in the room. However, I understand the first test searches for hepatitis C antibodies which means that at some point, a patient has had exposure to the disease. That does not mean the patient has the disease. The second test is a blood test that shows the presence or absence of a living virus within a patient's body. A positive result in that test means the patient has the disease and there is no doubt about it. For one in five people, their own immune system will clear that infection. That does happen, which is a positive.
