Letter from Dr H L Lloyd to Dr H H Gunson and Professor J D Cash re hepatitis C testing. Advises he has decided to commence testing by July 1 rather than the revised national date of September 1991. Expresses that his personal view is that not to test now that we have the ability to test would be indefensible under the current Product Liability Legislation. Asks whether any Centre is carrying out any additional tests such as Hep B core or ALT testing and if so which criteria are being used to select samples for testing.
