This study compared a panel of 10 enzyme-linked immunosorbent assays (ELISAs) for the serodiagnosis of Mediterranean visceral leishmaniasis (MVL). The ELISAs were based on either one of the following Leishmania antigens: crude soluble Leishmania antigens (SLAs), recombinant (r) antigens (namely: rgp63, rK39, gene B protein, r H2A and r H2B histones proteins, rLACK, rPSA-2, r P20) and purified l...

Five hundred urine samples were tested for cells and bacteria by using a commercial dipstick, a catalase screening device, standard culturing, and chamber counts. The sensitivities of the catalase test were 83% for all samples and 97.6% for specimens containing significant numbers of leukocytes and bacteria. The catalase screening test is simple to perform and should prove useful for the detect...

PURPOSE Accurate measurement of pH is necessary to guide medical management of nephrolithiasis. Urinary dipsticks offer a convenient method to measure pH, but prior studies have only assessed the accuracy of a single, spot dipstick. Given the known diurnal variation in pH, a single dipstick pH is unlikely to reflect the average daily urinary pH. Our goal was to determine whether multiple dipsti...

Diagnostic tests for visceral leishmaniasis that are based on antigens of a single Leishmania strain can have low diagnostic performance in regions where heterologous parasites predominate. The aim of this study was to investigate and compare the performance of five serological tests, based on different Leishmania antigens, in three endemic countries for visceral leishmaniasis. A total number o...

In order to determine the value of dipstick analysis of urinary protein in pregnancy induced hypertension, a prospective study analyzing pregnant patients with a diagnosis of hypertensive disorder was conducted to compare the result of urinary protein dipstick analysis with 24hr. urine protein collection in obstetrical clinics affiliated to Shiraz University of Medical Sciences. All patien...

background: immunochromatographic based rk39 antibody detection test became popular for the diagnosis of vis­ceral leishmaiasis (vl) because of high sensitivity, rapidity, easy to interpret, and cost effectiveness. however, false positive result after complete cure of the patients is the major limitation with this test. the aim of the study to access the usefulness of non-invasive samples i.e. ...

Aim—To evaluate the reliability of dipstick measurements of urine specific gravity (U-SG). Methods—Fresh urine specimens were tested for urine pH and osmolality (U-pH, U-Osm) by a pH meter and an osmometer, and for U-SG by three diVerent methods (refractometry, automatic readout of a dipstick (Clinitek-50), and (visual) change of colour of the dipstick). Results—The correlations between the vis...

To study the effect of months, seasons, age and sex on visceral leishmaniasis (VL) in human, data were collected during March 2010 through February 2011 from the register book of Upazila Health Complex (UHC) of Trishal, which is an endemic region for VL in the Mymensingh district. Besides, 70 blood samples were collected from suspected VL human patients to compare microscopy with rK39 immunochr...

OBJECTIVE To compare the effectiveness, benefits, and costs of two asymptomatic bacteriuria screening and treatment strategies to prevent pyelonephritis in pregnancy. METHODS A decision analytic model was created to compare strategies based on either 1) a leukocyte esterase-nitrite dipstick, or 2) on urine culture, with a policy of no screening or treatment. A literature search was conducted ...

We compared the two formats of rKE16 antigen-based rapid tests, a flowthrough test (KEFT) and a lateral flow test (KELF), with the rK39 rapid test for the diagnosis of visceral leishmaniasis. Sensitivities with KEFT (99%, 198/200) and rK39 (99.5%, 199/200) were comparable and higher than that with KELF (95.5%, 191/200). In the control groups comprising subjects with diseases from areas of nonen...
