Summary Urine specimens obtained from 192 female out‐patients attending a pyelonephritis unit were used to compare and contrast 2 varieties of commercially available dipinocula with one another, and with standard methods of bacteriological assessment. The dipinocula produced reliable results comparing favourably with one another and with standard methods. The rate of false negatives was 4.5 per cent (Oxoid) and 9 per cent (Uricult), while that of false positives was 2.1 per cent (Oxoid) and 2.6 per cent (Uricult). It is suggested that all patients in whom dipinoculum techniques indicate a positive, or equivocally positive, result ought to submit a further mid‐stream specimen of urine for more critical bacteriological examination.
