<unk>  (MIA) is a type of diagnostic<unk>  using<unk>  beads as labels in lieu of conventional enzymes (ELISA), radioisotopes (RIA) or fluorescent moieties (fluorescent<unk> s) to detect a specified analyte. MIA involves the specific binding of an antibody to its antigen, where a<unk>  label is conjugated to one element of the pair. The presence of<unk>  beads is then detected by a<unk>  reader (magnetometer) which measures the<unk>  field change induced by the beads. The signal measured by the magnetometer is proportional to the analyte (virus, toxin, bacteria, cardiac marker, etc.) concentration in the initial sample.
