HPV18 is normal.

If HPV18 is positive, although TCT is normal, cervical lesions cannot be ruled out. Because HPV18 is a high-risk type, persistent high-risk HPV infection is a predisposing factor for cervical cancer, especially HPV16 and 18. about 70% of cervical cancer is related to HPV16 and 18. Therefore, if HPV18 is positive, no matter whether TCT results are normal or not, cervical biopsy under colposcopy should be done. According to the test results, further treatment should be decided. For women with a sexual history, regular screening for cervical cancer is recommended.
