Abstract
Methods and cards for detecting an antigen or antibody in a fluid sample are disclosed. The fluid sample is added to a microreaction vessel containing a slurry suspension of inert particles and a binding partner to the antigen or antibody to be determined. The fluid sample is added to the micro reaction vessel, with one of the antigen and antibody binding partners being carrier bound. The vessel contents are centrifuged, to cause the binding partners to contact each other to form an optically detectable binding complex. The location of the optically detectable complex is observed to determine the presence of the antibody.
