Hologic, a manufacturer of diagnostic products, medical imaging systems and surgical products, has announced that the US Food and Drug Administration (FDA) has approved the Aptima HPV 16 18/45 genotype assay for use on the company's fully automated Panther system.

The Aptima HPV 16 18/45 genotype assay is performed using Hologic's ThinPrep liquid cytology specimen and is intended to be tested from the same sample that has already received Aptima HPV assay positive results.

Hologic's Aptima HPV 16 18/45 genotype assay is the first test FDA-approved for genotyping human papillomavirus (HPV) types 16, 18 and/or 45.

Detection of these HPV types as part of reflex testing may help clinicians identify up to 94% of all cervical adenocarcinomas.

Although HPV genotype 45 is fairly uncommon, identified in only 0.4% of women with normal cytology, data indicates that it is the third most common HPV genotype in invasive cancer.

The addition of HPV genotype 45 is designed to help identify more women at risk for adenocarcinoma, with minimal impact to colposcopy rates.

Studies have shown that HPV types 16, 18 and 45 are more likely to be integrated into the human genome than are the other HPV types, and tumors with these genotypes may present earlier.

Hologic Diagnostics group vice president Dr Rohan Hastie said: "The addition of the Aptima HPV 16 18/45 genotype assay to the Panther menu further extends the capability of low- to high-volume laboratories to run multiple tests from a single specimen, on a cost-effective, highly flexible and fully automated molecular testing platform."

The Aptima HPV 16 18/45 genotype assay is intended to test specimens from women with Aptima HPV assay positive results. The FDA has approved the test for two uses:

- In patients 21 years and older with atypical squamous cells of undetermined significance (ASC-US) cervical cytology results, the Aptima HPV 16 18/45 genotype assay can be used to test samples from women with Aptima HPV assay positive results to assess the presence or absence of high-risk HPV genotypes 16, 18 and/or 45.

- This information, together with the physician's assessment of cytology history, other risk factors, and professional guidelines, may be used to guide patient management. The results of this test are not intended to prevent women from proceeding to colposcopy.

In patients 30 years and older, the Aptima HPV 16 18/45 genotype assay can be used to test samples from women with Aptima HPV assay positive results.

The assay results will be used in combination with cervical cytology to assess the presence or absence of high-risk HPV genotypes 16, 18 and/or 45.

This information, together with the physician's assessment of cytology history, other risk factors, and professional guidelines, may be used to guide patient management.

The Aptima HPV 16 18/45 genotype assay was CE marked in December 2011 and received FDA approval on the Hologic high-throughput Tigris system in October 2012.
