ABSTRACT
Examination of 330 patients with pyuria, aged 18 months to 84 years, who attended the Outpatient Department of Siriraj Hospital during the period 1984 to 1988, disclosed proteinuria, and blood leukocytosis with neutrophilia in 70, 55 and 20 percent, respectively. Haemoglobin concentration and haematocrit value were decreased in 59 and 50 percent of the patients. Urine specimens containing over 30 white blood cells / high dry field yielded positive protein test. Nevertheless, there were no correlation between the number of white blood cells in urine and amount of urine protein, white blood cells and neutrophil in blood (correlation coefficient 0.37, 0.17 and 0.21, respectively); neither were correlation between the number of white blood cells in urine, haemoglobin and haematocrit (correlation coefficient – 0.14 and – 0.17, respectively).
