PRODUT DETAILS

Advanced Detection Technology
VETIVD™ cTT4 Rapid Quantitative Test utilizes the cutting-edge third generation
time-resolved immunofluorescence chromatography technology. It employs rare earth element
europium (Eu3+) coated nano-fluorescent microspheres as a distinctive marker, and swiftly
achieves quantitative analysis by analyzing the fluorescence intensity of both the detection zone
and quality control zone.
