POCT Point-of-care Testing Filters

POCT， Instant testing refers to clinical testing conducted next to the patient, usually not necessarily by a clinical examiner. It is a new method that analyzes samples immediately at the sampling site, eliminating the complex processing procedures during laboratory testing and quickly obtaining test results. The detection principle is based on various measurement methods such as fluorescence, chemiluminescence, Raman spectroscopy, and absorbance measurement. The testing items include coagulation testing, blood glucose testing, immune testing for infectious diseases, heart disease markers, cancer markers, and biological threat detection. POCT (bedside rapid detection) is divided into five categories of optical paths: fluorescence immunoassay, biochemical colorimetry, blood oxygen, chemiluminescence, and fluorescence PCR. The filter is the core device for the signal-to-noise ratio and detection accuracy of the whole machine, and all use dura TFF interference filters
