The system comprises a DNA concentration cartridge (101) adapted to isolate and enrich low-abundance HPV DNA, and a reaction tube (102) pre-loaded with isothermal amplification reagents specific to high-risk HPV genotypes. A portable isothermal heating device (103) maintains a constant reaction temperature of approximately 63 C 3 C to facilitate nucleic acid amplification. The amplified product is subsequently applied to a lateral flow strip (104) configured with test and control lines to provide a clear visual indication of HPV presence or absence. The system delivers results within one hour, enabling point-of-care and at-home screening applications."
