The normal value of SCC squamous cell carcinoma antigen is 0-1.5ug/l. Squamous cell carcinoma antigen is a kind of glycoprotein, which is mostly found in the cytoplasm of female cervical squamous cells. This test is only an auxiliary result and requires a colposcopic biopsy of the cervix to confirm the diagnosis of cervical cancer if malignant cervical lesions are found at the same time. It can also not be ruled out that other parts of the body cause the increase of SCC squamous cell carcinoma antigen, and other parts of the body, such as head and neck, lungs, etc., need to be investigated.
