title: Importance of using an HIV Ag/Ab combined assay in a UK population at high risk of acquiring HIV infection.
abstract: The combined assays for HIV p24 antigen and antibody (4th generation) have had a mixed reception in testing laboratories. A series of five cases detectable only by 4th generation assays or RNA viral load and negative in a variety of 3rd generation assays has prompted us to change our 'routine' screen to a combined assay.
