The present invention relates to immunoassay methods for detecting and measuring the amount of an analyte in a sample by means of generic anti-hapten antibodies. Also disclosed are multi-analyte immunoassay methods. Reagents, devices, and kits using the anti-hapten antibodies are also disclosed. The present invention also relates to immunoassay methods for detecting and measuring the amount of an analyte in a sample by means of a dual antibody format. The present invention also relates to dyed erythrocytes, preferably fixed, which are coated with antibodies. Also disclosed is the use of these dyed erythrocytes in agglutination assays to detect and measure the presence of an analyte in a sample. The analyte can be a hapten, an antigen, or an antibody. Also included are agglutination assays, compositions and kits using these dyed and coated erythrocytes. |
