- W249851653 abstract "Semi-quantitative urinalysis with urine reagent strips (URS) for erythrocyturia (EU), leucocyturia (LU) and proteinuria (PU) was performed in Congolese and Sudanese school children with Schistosoma haematobium and/or S.mansoni infection. Quantitative urinalysis was performed on the same specimen using microscopy and a Neubauer counting chamber for EU and LU and the Coomassie blue dye-binding assay for PU. Microscopi- cally detectable EU of more than 10 cells/gl was found in 63% of all samples and LU of more than 20 cells/gl was found in 60% of all samples. With the Coomassie blue method, PU of more than 150 mg/1 was detected in 51% of all samples. URS gave positive results of grade 1 - 3 for EU in 69% of all samples, for LU in 63% of all samples and for PU in 66% of all samples. The sensitivity and specificity of URS compared with standard reference methods were as follows: EU 95% and 75%, LU 81% and 81% and PU 90% and 56%. When the results of all three test were combined, URS differentiated abnormal from normal urine specimens with a sensitivity of 94% and a specificity of 70%. Median quantitative results showed a good correlation with semi- quantitative URS readings for all parameters, but there was a wide range of URS scores. We concluded that URS sensitively detect urinary ab- normalities and thus may be used as a general screening method under field conditions when more specific methods cannot be performed. In the hospital laboratory, urine mi- croscopy with a counting chamber would be preferred to URS as a sole method for EU and LU detection; URS is useful for the detection of PU in the tropical hospital labo- ratory where an appropriate quantitative method with a better specificity may not be available." @default.
