High-Sensitivity HPV (2+16) Molecular Detection for Early Cervical Cancer Screening

Human Papillomavirus (HPV) infection is widely recognized as one of the primary causes of cervical cancer, which remains a leading threat to women’s health worldwide. Persistent infection with high-risk HPV (HR-HPV) types, particularly HPV 16 and HPV 18, is strongly associated with the development of cervical intraepithelial neoplasia and malignant transformation. Therefore, early and accurate detection of high-risk HPV is essential for effective screening, prevention, and clinical intervention.

Các Bộ xét nghiệm phát hiện Cowingene HPV (2+16) (Dạng lỏng) is an advanced in vitro diagnostic (IVD) solution designed for the qualitative detection of HPV DNA using real-time PCR technology. The kit enables simultaneous detection of 18 high-risk HPV types in a single assay, while specifically genotyping HPV 16 and HPV 18, providing critical clinical insights for risk stratification and patient management.

Intended Use: Comprehensive High-Risk HPV Detection for Clinical Diagnosis

This detection kit is intended for the qualitative detection of HPV DNA in human clinical specimens. It supports the identification of:

HPV 16 and HPV 18 (individually typed) 

16 additional high-risk HPV types, including:
26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 73, and 82

By combining specific genotyping (16/18) with broad-spectrum high-risk screening, the kit provides a balanced approach to HPV detection—allowing clinicians to identify both the most oncogenic types and other clinically relevant high-risk infections.

The results serve as important auxiliary evidence for cervical cancer screening, early diagnosis, and follow-up monitoring, supporting healthcare providers in making informed clinical decisions.

Validated Sample Types: Flexible and Patient-Friendly Collection

The kit is validated for use with the following specimen types:

Urine samples

Cervical swabs

This flexibility enables both clinician-collected and self-collected sampling approaches, improving patient compliance and expanding access to screening programs. Urine-based testing also offers a non-invasive alternative, making it particularly suitable for large-scale population screening.

Performance Characteristics: Exceptional Sensitivity and Reliability

Ultra-High Sensitivity

The kit demonstrates an analytical sensitivity (LoD) of 100 copies/mL, allowing detection of very low levels of HPV DNA. This is critical for identifying early-stage infections before clinical symptoms or cytological abnormalities appear.

Excellent Specificity and No Cross-Reactivity

Extensive validation shows that the kit has no cross-reactivity with non-target pathogens commonly found in the reproductive tract, including:

Chlamydia trachomatis 

Neisseria gonorrhoeae 

Candida albicans 

Trichomonas vaginalis 

Gardnerella vaginalis 

Ureaplasma species and other HPV types not included in the panel

This ensures highly accurate detection and minimizes false-positive results.

Strong Anti-Interference Capability

The assay performance is not affected by common interfering substances such as:

Hemoglobin

White blood cells

Cervical mucus

Vaginal care products and lubricants

Antibiotics such as metronidazole

This robustness reflects real clinical sample conditions and enhances test reliability.

No Competitive Interference Between Targets

Detection of HPV 16, HPV 18, and the other 16 high-risk types does not interfere with each other, ensuring accurate multiplex detection across all channels.

High Precision and Reproducibility

The kit demonstrates excellent precision, with coefficient of variation (CV ≤ 5%) across:

Different days (intra/inter-day)

Different batches

Different operators and testing sites
