A radial gel diffusion method utilizing urease and bromthymol blue has been developed for urine stain identification. Urea, present in urine in relatively high concentrations, can be detected from urine stain extracts. This technique provides both qualitative and quantitative results, and is sensitive enough to detect 0.078 µg/µL of urea.
