The present invention concerns a device for analyzing biological parameters from a sample ( 6 ) comprising (i) first transferring means ( 5, 20, 25 ), (ii) first preparing means ( 7 ), (iii) means for measuring cellular components ( 8 ), (iv) second preparing means ( 10, 11, 22, 23, 24 ) capable of carrying out, on a sample from the first preparing means ( 7 ), at least one dilution with an assay reagent (R 3 ) comprising particles functionalized at the surface with at least one ligand specific to at least one analyte of interest, (v) immunodetection measurement means ( 30, 31 ) capable of assaying at least one analyte of interest by measuring the aggregation of functionalized particles, said device further comprising (i) second transferring means ( 4, 21, 22, 26 ) at least partially separate from the first transferring means ( 5, 20, 25 ) and (ii) means for applying a magnetic field ( 28 ) capable of causing, by magnetic interaction, an acceleration of the aggregation of said functionalized particles, which comprise magnetic colloidal particles. The invention also concerns a method implemented in said device. |
