The screening method comprises the following steps: (S1) acquiring a large number of freeDNA sequences from a blood sample of a patient with cytic echinococcosis by virtue of a re-sequencing technique; (S2) carrying out comparative analysis by virtue of a bioinformatics method so as to screen out echinococcus granulosus-sourced free DNA sequences; and (S3) carrying out verification and screening in patients with the echinococcosis and healthy people through a fluorescence quantitativePCR method, so as to obtain the free DNA sequence derived from the echinococcus granulosus. Besides, the invention further discloses application of the free DNA sequence derived from the echinococcusgranulosus in preparation of products for diagnosing and detecting the echinococcosis. A detection result shows that the free DNA sequence has relatively high sensitivity and specificity in detectionof the patient with the echinococcosis and has excellent application prospects in the diagnosis and detection fields of the echinococcosis.
