For the detection of a virus associated with cervical cancer in a Papanicolaou smear, which assay is suitable?

The detection of a virus associated with cervical cancer, specifically Human Papillomavirus (HPV), is best accomplished through a molecular assay for HPV. Molecular assays, such as PCR (polymerase chain reaction), are highly sensitive and can directly identify the viral DNA present in cervical cells. This method is crucial for detecting high-risk HPV types that are known to be associated with cervical cancer.

While ELISA assays can be used to detect antibodies, they do not provide direct evidence of an active HPV infection; they may only indicate previous exposure or immunity. Additionally, assays for HSV-2 (Herpes Simplex Virus Type 2) are not relevant in the context of cervical cancer, as HSV-2 does not play a significant role in the etiology of this type of cancer.

Thus, the molecular assay for HPV is the most suitable choice for detecting the virus linked to cervical cancer in a Papanicolaou smear, allowing for timely diagnosis and management of potential cervical cancer risks.
