Abstract

The present invention provides an immunological detection method for an analyte in a whole blood sample, a magnetic microsphere, and a magnetic microsphere-protein complex. The immunological detection method includes: a) mixing and incubating the whole blood sample with an immunological detection reagent to obtain an incubation complex, wherein the immunological detection reagent includes a signal molecule and/or a magnetic microsphere-protein complex; the magnetic microsphere-protein complex includes a magnetic microsphere and a first affinity protein coated on the magnetic microsphere, the first affinity protein is a protein that can specifically bind to the analyte, and the surface of the magnetic microsphere includes methacrylate; and b) performing signal detection on the incubation complex, and obtaining the amount of the analyte based on signal intensity. The method can address the problem of low accuracy of whole blood sample detection in prior art and is suitable for the field of whole blood sample detection.
