    Re: Dipsick examination of urine

    Dear Editor,

    Our study[1] was done on a selected group of children who were at an increased risk of having urinary tract infection (UTI). The inclusion criteria were the presence of any of the following

    1. Clinical suspicion of UTI
    2. History of previous UTI or renal anomalies
    3. Children requiring antibiotics (urine culture was send prior to starting antibiotics)...

    Dear Editor:

    We read with interest the letter by Thayyil-Sudhan and Gupta[1] reporting their study on the role of dipsticks in the detection of urinary tract infection in children. We believe that this is a very important subject and wish to comment on the report and their conclusions in the light of our published study.[2]

    We note that 188 urines were not sent for culture, it is not therefore possible to d...

    Re: Dipstick examination for urinary tract infections: misleading analysis?

    We agree with Dr Deshpande that the sensitivity quoted for dipstick testing might not be the "true value" as a screening test for urinary tract infection as urine culture was not done on all the children in the study.

    Our study was based on the current practice at our hospital of sending urine for culture if any dipstick (nitrites, protein, leucocyte esterase or blood) was abnormal or if there was a clinical su...

    Dipstick examination for urinary tract infections: misleading analysis?


    Thayyil-Sudhan and Gupta suggest that urine culture needs to be undertaken if any of the four indices of dipstick analysis (nitrates (sic), blood, protein or leucocyte esterase) are abnormal (1) based presumably on the high sensitivity and negative predictive value (NPV) of this criterion. However, the design of their study wherein urine cultures were not performed on the majority of samples where dips...
