Abstract: Method for in vitro detection and/or quantification and/or identification of infectious compounds present in a fluid medium M constituting a biological material, in which method a suspension of microbeads of solid polymer material capable of binding proteins is prepared; the microbeads are loaded with ?2GPI proteins by coupling with a sufficient amount of ?2GPI proteins; said microbeads are brought into contact with the fluid medium M while adding ions of at least one oxidizing metal, so as to bind the infectious compounds to the ?2GPI proteins; the microbeads thus prepared are separated from their suspension medium, so as to obtain a residue; and the infectious compounds of the residue are detected and/or quantified and/or identified.
