The HPV 16+18 E7 Antigen Test is a rapid chromatographic immunoassay for the qualitative detection of E7 oncoprotein antigens associated with Human Papillomavirus (HPV) types 16 and 18 in cervical cell samples. It is designed to aid in the screening and assessment of infection with these high-risk HPV types, which are strongly implicated in the development of cervical cancer.
