Objective: The purpose of this study is to evaluate the diagnostic value of nitrite test in comparison with urine culture (U/C) results in patients with Urinary tract infection (UTI) symptoms.Methods: This cross-sectional study was performed on 203 patients with UTI symptoms. Middle urine sample was taken into sterile plastic containers, and simultaneously the urine sample and the nitrite...

urine dipstick is a useful and commonly used test because of its rapidity and low cost; however its diagnostic accuracy is debatable. this research were carried out to determine sensitivity, specificity and positive and negative predictive values of nitrite (nit) and leukocyte esterase (le) testing in relation to urine culture. this research was conducted on 100 hospitalized patients with clini...

All samples should be midstream and collected in a clean sterile container. Suprapubic aspiration or fresh catheter samples are ideal, but not always practical. The gold standard method of testing is to remove a small volume of urine from the sterile container with a fresh sterile syringe, and then apply the removed urine to the dipstick. In this way, the remainder of the collected sample conte...

introduction and aim: ip-10 molecule is a new biomarker to predict response to treatment in chronic hcv infection. also urine ip-10 has been suggested as a biomarker in other infections. but already, it has low data in urine as well as serum level of ip-10 for hcv infection. the aim of this study was to assess urine and serum level of ip-10 in patients with type 1 and 3a hcv infection. material...

In this study, a high-performance liquid chromatographic method (HPLC) and UV spectrophotometric method were developed, validated and applied for the determination of theophylline in biological fluids. Liquid- liquid extraction is performed for isolation of the drug and elimination of plasma and saliva interferences. Urine samples were applied without any extraction. The chromatographic separat...
