Abstrakt: High-risk human papillomavirus (HPV) screening is crucial for cervical cancer prevention. However, laboratory-based nucleic acid amplification tests (NAATs) require costly equipment, designated lab space, and skilled personnel. Additionally, cervical swabs collected by healthcare professionals can be inconvenient, uncomfortable, and reduce privacy, limiting broader application and patient compliance. A SlipChip-based Integrated Point-of-Care (SIPOC) system featuring an injection-molded SlipChip is presented with preloaded reagents for nucleic acid extraction and a portable four-channel real-time quantitative PCR instrument for detection. This system incorporates a self-sampling method that allows participants to collect their own vaginal swabs, with the β-Globin gene as a control. After testing 130 participants for HPV-16 and HPV-18, 97.7% of the self-collected samples are valid. Among valid samples, 25 tested positive for HPV-16 and 9 for HPV-18. Compared to Roche's standard HPV PCR test, the SIPOC system shows 100% positive predictive value (PPV) for both HPV-16 and HPV-18 and negative predictive values (NPVs) of 99.0% and 99.1%, respectively. This system is promising for HPV screening in resource-limited settings and adaptable for other point-of-care NAAT applications, including home testing.
