cobas<sup>®</sup>4800 HPV Test, a real-time polymerase chain reaction assay for the detection of human papillomavirus in cervical specimens
Bibliographic record
Abstract
Cervical cancer screening incorporating high-risk human papillomavirus (HPV) detection has become the preferred screening strategy in some countries and is increasingly more widespread in other countries with organized or opportunistic screening programs. Given knowledge that high-risk HPV genotypes differ in their oncogenic potential, commercial HPV assays with genotyping capabilities have been developed and have garnered attention in the recent literature. The cobas 4800 HPV Test is a qualitative multiplex assay that provides specific genotyping information for HPV types 16 and 18, while concurrently detecting 12 other high-risk HPV genotypes as a pooled result. It is currently the only clinically validated, US FDA-approved assay with this capability. Since HPV types 16 and 18 have been designated as conferring the greatest risk for cervical disease, their detection may prove useful in guiding patient management.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
