Microfluidic chip for separation and detection of whole blood sample, and detection method thereof

The invention provides a microfluidic chip for separation and detection of a whole blood sample. The microfluidic chip comprises a chip body, which is provided with a sample flow channel, wherein thesample flow channel comprises a sample injection zone, a sedimentation zone, a mixing zone, a detection zone and a waste liquid zone, the sample injection zone, the sedimentation zone, the mixing zone, the detection zone and the waste liquid zone are sequentially connected, the sedimentation zone comprises a sample injection part and a sedimentation part, a ratio of the maximum width of the sedimentation part to the maximum width of the sample injection part is 2-10, the sedimentation part has a structure with the wide middle portion and both narrow edge portions, the front side walls and therear side walls of both end portions of the sedimentation part are respectively an inclined surface, the extending lines of the front side wall and the rear side wall intersect to form an included angle, and the front side wal
