Which of the following diagnostic tests for HIV uses the Electrochemiluminescence (EQL) method?

I. The first incubation consists of mixing the user's sample with monoclonal antibodies anti-p24 marked with biotin, recombinant antigens specific to HIV marked with biotin, synthetic peptides specific to HIV marked with ruthenium complex, monoclonal antibodies anti-p24 marked with ruthenium complex, and recombinant antigens specific to HIV marked with ruthenium complex.
II. The presence or absence of anti-HIV-1 and/or anti-HIV-2 antibodies or p24 antigen in the sample is determined by the intensity of the chemiluminescent emission obtained compared to the cut-off point.
III. The solid phase is a cone, with the upper part coated with anti-p24 antibodies and the lower part coated with recombinant antigens and synthetic peptides of HIV-1, including those of group O and HIV-2, allowing the detection of anti-HIV antibodies.
IV. The reaction mixture is aspirated into a reading cell, where the microparticles are magnetically fixed to the surface of an electrode. The unbound elements are removed, and the application of an electric current to the electrode induces a chemiluminescent emission, which is measured by a photomultiplier.
a) I and II are correct.
b) II and III are correct.
c) III and IV are correct.
d) I, II, III, and IV are correct.
