The present invention proposes the use of a specific lectin combination in preparing test vectors for identifying epithelial ovarian cancer and a kit. For saliva samples, the specific lectin combinations are: (1) the combination of PSA, SNA, MAL‑II, ECA and HHL, corresponding to healthy people; (2) the combination of PHA‑E, LTL and PNA, corresponding to benign Patients with ovarian disease; (3) The combination of RCA120, UEA‑I, ConA, LCA, AAL, WFA, WGA, DBA, VVA, NPA and GNA, corresponding to patients with epithelial ovarian disease. By specifically binding lectins to glycoprotein sugar chains in saliva, differentially expressed glycoproteins and sugar chain structures in patient saliva samples can be quickly detected, achieving rapid and high-performance detection of multiple glycoproteins and sugar chain structures in the samples. Flux detection.
