Description

technical field [0001] The invention relates to the technical field of gene molecular diagnostic reagent equipment, in particular to a sample crystal particle detection system and method with excellent stability and reproducibility, ultra-high sensitivity, and extreme accuracy. Background technique [0002] At present, fluorescence quantitative PCR (Fluorescence Quantitative Polymerase Chain Reaction, qPCR) has developed into a key conventional technology in the field of in vitro molecular diagnosis, which has greatly promoted the development of life science in the field of health care. However, fluorescence quantitative PCR quantification is only relative quantification, and its accuracy and reproducibility still cannot meet the development needs of the current field of in vitro molecular diagnostic systems and biological genetics research. However, in many projects such as liquid biopsy and NIPT, there are some technical bottlenecks. For example, the content of tumor circu...
