title: [Patients with an indeterminate serological diagnosis of HIV-1 infection].
abstract: Western blot is the technique most frequently used to determine the presence of HIV-1 antibodies. However, some patients remain with an indeterminate diagnosis for HIV-1 according to the technique. We followed 8 such patients for 2 to 18 months. Immunologic studies included standard ELISA, immunofluorescence and Abbott anti-p24 ELISA. We found selective reactivity for certain viral proteins such as isolated p24, p24 plus p51 or p55, gp41 plus gp 120, p17 plus p24 and p25.
