Letter: Screening methods for covert bacteriuria.

Screening for bacteriuria.

Cost-effectiveness of two methods of screening for asymptomatic bacteriuria.

A comparison of two methods of screening schoolgirls for asymptomatic specimens of urine from 96.3, but that the home self-administered use of dipslides was successful in only 70.2%. The failure to obtain the return of satisfactory dipslides was most frequent in children under seven and over 11 years of age, and in children from the lower social classes; satisfactory dipslides were returned by ...

Evaluation of six screening methods for detecting significant bacteriuria.

Six screening methods for the successful detection of significant bacteriuria--electrical impedance (Malthus), automated acridine-orange staining (Autotrak), particle counting (Ramus), bioluminescence, nitrite and leucocyte test strip (BM Nephur), and microscopy--were evaluated. All had excellent predictive values for a negative result (97%-100%) but were less accurate in predicting a positive ...

Urinary tract in schoolgirls with covert bacteriuria.

During screening of 16,800 primary schoolgirls, aged 4-12 years, in Cardiff and Oxford, significant bacteriuria was found in 294 (1-7%). Intravenous urography and micturating cystography were performed in 246 of these girls. The urinary tract was abnormal in 47%. Pyelonephritis with or without vesicoureteric reflux was present in 26% and reflux without renal abnormality in a further 16%. The pr...

Screening for bacteriuria with Clinitec-200.

A method of testing for bacteriuria with multiple reagent strips for blood, nitrite, and leucocyte esterase was evaluated. Of 669 urine specimens tested, 267 were negative on the reagent strips and so would ordinarily be discarded, creating a reduction in the workload of culturing urine specimens of 40%. Thirteen of these were false negative results, however, which represented 10% of all the sa...
