The Studies on Urobilinogen Determination

Urobilinogen 측정에 관한 연구

We have performed 324 specimens' urobilinogen determinations(Healthy normal 219 & out-or in-patients 105) for the purposs of defining accurate & precise methods in semi-quantitative techniques. As shown on Table 1 through 5 & Fig.1 to 3, normal person's titer is concentrated in 1:40, 1:80, 1:20 & 1:10 respectively and majority of patients' titer is 160. The concentration diagram on Fig. 2 is seen for the normal person and patient's titer is nearly normal distribution scattered from 0.475mg/dl of median throughout the whole area (0.225-0.625). From Fig. 5 I have found that semi-quantitative titer is much different from the true value by electrical measurements. I am proposing of taking photoelectric quantitative methods for semiquantitative methods.
