Abstract:
Objective To design a new type of fluorescence detection optical system for dedicated neonatal PKU screening. Methods The system selects super-luminance UVLED for excitation light source, uses different diameter quartz fiber and Y -type optical fiber which consists of glass fiber bundles, and self focusing optical fiber for collimating light and photomultiplier tubes for testing. Results The system has many features, such as simple structure, small size and high sensitivity. Conclusion The clinic screening requirements are met by the system and a new means of rapid detection is provided for PKU screening in large quantities.
