BACKGROUND Microalbuminuria is a marker of early kidney disease and high cardiovascular risk in various populations, including HIV positive patients. However, the diagnostic value of qualitative (dipstick) proteinuria and the burden of microalbuminuria in HIV positive patients living in sub-Saharan Africa are relatively unclear. METHODS In a cross-sectional study, 235 HIV- positive outpatient...
22 Objective: To determine how urine dipstick test, edema, and/or excessive weight gain 23 (EWG, defined as ≥ 500 g/week) at antenatal visits predict significant proteinuria 24 (defined as a protein-to-creatinine ratio [P/Cr, mg/mg] ≥ 0.27) and preeclampsia. 25 Methods: Data from 3279 antenatal visits between 30 and 36 weeks of gestation were 26 studied in 783 women with singleton pregnancies. ...
Introduction: There is a lack of evidence supporting the routine use of laboratory tests to detect bladder cancer. Identifying a cost-effective and widely available diagnostic aid may improve bladder cancer outcomes. We sought to evaluate the utility of dipstick urinalysis to detect microhematuria and diagnose bladder cancer in a large, diverse, contemporary cohort. Methods: All non-pregnant wo...
background: the mediterranean type of kala-azar is occurred in different parts of iran and caused by leishmania infan tum. a rapid and valid test for early detection of visceral leishmaniasis in human would be highly desirable because it could de crease mortality rate of the disease. in this study, we aimed to compare the results of k39sub antigen with an commercial immu nochromatographic dipst...
We performed a multicenter evaluation of a robust and easily performed dipstick assay for the serodiagnosis of human leptospirosis. The assay is aimed at the detection of Leptospira-specific immunoglobulin M (IgM) antibodies. The study involved 2,665 serum samples collected from 2,057 patients with suspected leptospirosis in 12 countries on five continents with different levels of endemicity an...
OBJECTIVE To compare the performance of the direct agglutination test and rK39 dipstick for the diagnosis of visceral leishmaniasis. DATA SOURCES Medline, citation tracking, January 1986 to December 2004. Selection criteria Original studies evaluating the direct agglutination test or the rK39 dipstick with clinical visceral leishmaniasis as target condition; adequate reference classification;...
Culture and serology were performed on blood and serum samples collected at or shortly after admission from 473 patients presented with suspected clinical typhoid. Clinical symptoms at first presentation including confusion, hepatomegaly, splenomegaly, abdominal pain, anemia, and gastrointestinal bleeding were non-specific as they were observed even more often in non-typhoid patients. Culture c...
BACKGROUND The dipstick test is widely used as a primary screening test for detection of significant proteinuria in pregnancy (SPIP). However, it often shows a false positive test result. This study was performed to determine which pregnant women should be recommended to undergo determination of urinary protein-to-creatinine ratio (mg/mg, P/Cr test) after dipstick test for confirmation of SPIP....
Examination of 4379 routine urinalysis specimens with dipsticks sensitive to ascorbic acid showed that 22.8% were positive specimens. The mean urinary vitamin C concentration in this population was 2120 mumol/L. There was a high rate of false-negative dipstick results for hemoglobin in patients with vitamin C in the urine. The highest false-negative rates were observed in urine samples containi...
