The invention relates to the technical field of serum preparation, and particularly discloses a method for preparing serum by extracting fibrin from plasma, which comprises the following steps: S1, collecting a plasma sample to be calibrated; s2, adding liquid calcium chloride into the collected plasma sample to obtain treatment liquid I; s3, fully stirring the treatment liquid I obtained in the step S2, and obtaining a treatment liquid II after stirring; s4, standing the treating fluid II obtained in the step S3, and performing centrifugal treatment by using a centrifugal machine after standing to obtain treating fluid III; and S5, standing the treating fluid III obtained in the step S4, and filtering out precipitates in the treating fluid III through filtration to obtain the prepared serum. S6, reserving at least one part of the prepared serum as a standby sample, and storing for later use; according to the method for preparing the serum, the fibrin is extracted from the plasma through filtration, and the o
