Ponatic 3, as the new series of molecular point-of-care testing (POCT) platform, integrates "Nucleic acid extraction”,“PCR amplification”and“Data analysis”into one system based on Sansure patented one-tube sample release technology. Collocating with prepackaged reagent, it only needs minimum steps and can achieve “sample-in, result-out”. This system can be used not only in large hospitals, but also in different scenarios such as primary medical institutions, fever clinics, customs, airports and other fields.
