Abstract:

Objective To evaluate the bacteriological information of SYSMEX UF-1000i urinalysis analyzer in screening urinary tract infections（UTI）. Methods A total of 314 specimens of midstream urine were collected from outpatients and inpatients in Longhua Hospital affiliated to Shanghai University of Traditional Chinese Medicine from April 27 to September 14,2016. These specimens of midstream urine were determined by microbiological culturing and UF-1000i. The results of Rods and Cocci/Mixed information of UF-1000i were compared with those of microbiological culturing. Results The sensitivity and positive predictive value of Rods in predicting negative bacillus were 76.8% and 70.0%,respectively. The sensitivity and positive predictive value of Cocci/Mixed in predicting positive coccus or mixed infection were 38.1% and 16.3%,respectively. Conclusions When UF-1000i indicates Rods,it can distinguish the types of bacteria preliminarily,guide the rational use of antibiotics in clinic and shorten the duration of treatment. When UF-1000i indicates Cocci/ Mixed,the results are diverse and are needed to be improved.
