 Immunochromatographic test strip and detection method using immunochromatography for detecting object in red blood cell-containing sample patent thumbnailImmunochromatographic test strip and detection method using immunochromatography for detecting object in red blood cell-containing sample
A problem to be solved by the present invention is to provide an immunochromatographic test strip and a detection method using immunochromatography avoiding aggregation of colloidal gold conjugates while red blood cells in whole blood are agglutinated and then separated and removed in the case of using polybrene as a blood-agglutinating agent and the colloidal gold conjugates as a detection reagent.
