Objectives To determine the effectiveness of two reagent strips in det
ecting significant bacteriuria amongst patients attending for urodynam
ic assessment. Patients and methods Four hundred patients undergoing u
rodynamic assessment were recruited for the study. Routine diagnostic
catheter specimens of urine were tested for nitrite, leucocytes and pr
otein. Results The leucocytes and nitrite strips had a high specificit
y rate of 99.5%. The frequency of significant bacteriuria in our popul
ation was 7% (n=28). Conclusion Culturing samples which test negative
for these strips is unnecessary. Reagent strip testing of urine provid
es a cheap, rapid method of screening for infection.
