The normal value of squamous cell carcinoma-associated antigen is generally ≤1.5ng/ml, but this index has uncertainty, because the normal range of data may be different because of different hospital examination environment and machines. After getting the test report sheet, you can observe the normal range of the reference value in the report sheet. High squamous epithelial cell carcinoma-associated antigen is commonly found in tumors such as cervical cancer and lung cancer in the body. If the related antigen value is mildly high, further examinations, such as CT, MR, ultrasound, etc., can be performed to check whether there are solid tumors in the body, and if the examination is normal, a slightly high antigen value means there is no problem.
