  • Main Image Navi
Hybrid Capture 2 (HC2) technology serves as the platform for QIAGEN’s nucleic acid hybridization assay for detection of human papillomavirus (HPV). This diagnostic method allows rapid, standardized testing of genetic material of the infectious agents in virtually any laboratory setting. It employs specific RNA probes, hybridization, antibody capture, and signal amplification that utilizes qualitative chemiluminescent detection.

The digene HPV Test, using Hybrid Capture 2 technology, provides an accurate, cost-effective, user-friendly method by achieving reliable and reproducible detection.

How HC2 technology works

Benefits of HC2

  • Full-length probe for reliable senstivity and specificity with no risk due to deletions
  • Unmatched cervical intraepithelial neoplasia (CIN) 2+ sensitivity
  • Same day results in a microplate test format
  • High-throughput automation for handling increasing test volumes
  • Minimal specimen preparation required for fast and efficient sample processing
  • Signal amplification method with reduced cross-contamination risk
  • Extensive, clinical validation data available

Back to topClinical sensitivity is critical

For routine HPV diagnostics and clinical decision making, clinical sensitivity is critical. The HC2 technology fulfills this requirement better than any other method as outlined in multiple clinical validation studies. Cervical cancer screening methods require HPV detection correlating to disease and not to the sheer presence of the virus, since 90% of infections is cleared by itself without consequences.
HC2 technology measures sensitivity versus defined clinical endpoints (CIN 3+/SCC) and ensures reporting of positive results only when risk of disease progression exists. QIAGEN’s digene HPV Test has an excellent clinical sensitivity of up to 100% in primary adjunctive screening when combined with a Pap smear test [Mayrand, M.H., et al. (2007) N. Engl. J. Med. 357(16), 1579.].
  • Clinically validated cutoff of 5000 copies/ml
  • Proven in extensive multiple trials
  • Ensures high negative predictive value
