Rapid HPV 16/18/45 Molecular Detection with NATBox for Targeted Cervical Cancer Screening

Human Papillomavirus (HPV) infection is the primary cause of cervical cancer, with certain high-risk genotypes responsible for the majority of cases worldwide. Among them, HPV 16, HPV 18, and HPV 45 are recognized as the most clinically significant types due to their strong association with high-grade lesions and invasive cervical cancer. Early and accurate detection of these high-risk HPV types is essential for timely intervention, risk assessment, and effective patient management.

การ Cowingene HPV 16/18/45 Detection Kit (NATBox) is an advanced in vitro diagnostic (IVD) solution designed for the qualitative detection of HPV DNA using real-time PCR technology. Integrated with the fully automated NATBox system, this kit provides a rapid, accurate, and streamlined molecular diagnostic solution for targeted cervical cancer screening.

Intended Use: Focused Detection of High-Risk HPV for Clinical Decision Support

This detection kit is intended for the qualitative detection of HPV DNA in clinical specimens, specifically identifying the following high-risk genotypes:

HPV 16

HPV 18

HPV 45

By focusing on these key oncogenic types, the kit provides clinicians with highly relevant diagnostic information for evaluating cervical cancer risk and determining appropriate follow-up strategies.

The test results serve as important auxiliary evidence for clinical diagnosis, screening, and monitoring of HPV-related infections, supporting early intervention and improved patient outcomes.

Validated Sample Types: Flexible and Patient-Friendly Sampling Options

The kit supports the following specimen types:

Urine samples

Cervical swabs

This flexibility enables both non-invasive and clinician-collected sampling methods, improving patient compliance and facilitating broader participation in screening programs. Urine-based testing is especially valuable for large-scale or community-based screening initiatives.

NATBox System: Fully Automated Molecular Testing Platform

A key highlight of this product is its integration with the NATBox® Mini II system, an automated molecular diagnostic platform that simplifies and standardizes the entire testing process.

Integrated Workflow Automation

The NATBox system performs:

Sample preparation

Nucleic acid extraction

PCR amplification

Target detection

within a single platform, significantly reducing manual intervention.

Self-Contained Cartridge Design

Each test uses a single-use cartridge that contains all necessary PCR reagents. This design offers:

Minimal risk of cross-contamination

Improved biosafety

Consistent and reproducible results

Point-of-Care Compatibility

The compact and automated design makes the system suitable for:

Hospitals

Clinics

Decentralized laboratories

Resource-limited settings

Performance Characteristics: High Sensitivity and Reliable Results

High Analytical Sensitivity

The kit achieves a limit of detection (LoD) of 100 copies/mL for HPV 16, 18, and 45, enabling reliable detection even in low viral load samples and early-stage infections.

Excellent Specificity and No Cross-Reactivity

Validation studies confirm that the kit shows no cross-reactivity with non-target pathogens, including:

Chlamydia trachomatis 

Neisseria gonorrhoeae 

Candida albicans 

Trichomonas vaginalis 

Gardnerella vaginalis 

Ureaplasma species and other HPV types

This ensures high diagnostic accuracy and reduces false-positive results.

Strong Anti-Interference Capability

The test 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 ensures reliable performance under real clinical conditions.

High Precision and Reproducibility

The kit demonstrates excellent precision, with CV ≤ 10%, ensuring consistent results across:

Different testing days

Different reagent batches

Different operators and testing environments
