Abstract: A quality detection method of an immunochip is disclosed. At least part of a surface of the immunochip is a modified surface with modifying groups. The method comprises: applying a detection solution containing a labeled antibody on the modified surface of the immunochip, the labeled antibody is an antibody connected with a labeling substance, and the labeled antibody is capable of reacting with the modifying groups and bonding to the modifying groups; removing the labeled antibody that has not reacted with the modifying groups, and detecting the content of residual labeled antibody on the modified surface; and identifying the quality of the immunochip according to the content of residual labeled antibody.
