BACKGROUND Variation in different urinary measurements for evaluation of iodine status is of concern to clinicians and researchers. OBJECTIVE This study evaluated variations between urine iodine concentration (UIC), spot and 24-h urine sample creatinine concentrations, and 24-h urine iodine excretion (24-h UIE) in repeated samples from school-age children. METHODS Urine samples (24 h and mo...

Stability of cannabinoid compounds in urine samples were evaluated using several storage temperatures. Appreciable losses (> 22.4 percent) were observed in some urine samples, after being stored at room temperature for 10 days. Lower losses (8.1 percent) were observed when the urine samples were refrigerated for 4 weeks. The behavior of urine samples depended on the analyzed urine. This could b...

We describe the kinetics of Zika virus (ZIKV) detection in serum and urine samples of 6 patients. Urine samples were positive for ZIKV >10 days after onset of disease, which was a notably longer period than for serum samples. This finding supports the conclusion that urine samples are useful for diagnosis of ZIKV infections.

Chlorinated hydrocarbon solvents are often used for dry-cleaning clothes in the laundry industry. The object of this study was to monitor the occupational exposure of dry-clean employees coming into contact with VOXs. Twenty five workers collected their urine samples before the work shift, after 4 h of work and after the work shift. The analyses of urine samples and solvents used in dry-cleanin...

We recently reported the production of the recombinant kinesin-related protein of Leishmania donovani with a molecular weight of 42 kd (rKRP42) and the value of the antigen in serum-based ELISA for the diagnosis of visceral leishmaniasis (VL). In this study, the rKRP42 antigen was validated with ELISA using urine samples (rKRP42 urine ELISA). The urine-based ELISA showed 94% sensitivity (108 po...

Introduction: Urine morphine test, in several countries is the most primarily available qualitative test for detecting opioid abusers. Since the users of illicit drugs attempt to defeat urine tests and there are also plenty of claims that usage of HD (high dose) contraceptive pills can result in false-negative results, we decided to design the present study to investigate the probable in vit...

introduction: ureaplasma uriealyticum is one of the most important causes of nongonococcal and nonspecific urethritis (ngu & nsu) in men. mycoplasma hominis too has a causal role in ngu & nsu. this study aimed to investigate whether it is possible to detect mycoplasma hominis and ureaplasma uriealyticum in first voided urine samples in men suffering from ngu & nsu without complaints of urethral...

BACKGROUND The urine protein:creatinine ratio (UPC) is used to quantify urine protein excretion and guide recommendations for monitoring and treatment of proteinuria. HYPOTHESIS/OBJECTIVES Home urine samples will have lower UPCs than hospital samples. The objectives were to compare UPCs of samples collected in each setting and to determine whether environment of sample collection might affect...

conclusions with regard to the ease of urine sample preparation and the 100% specificity the pcr method, performing urine pcr could be used as a diagnostic aid in ptb cases obtaining sputum samples is problematic. results results of the current study indicated that 48 (62.3%) patients out of 77 had a positive sputum culture. urine cultures and acid-fast smears were negative. urine pcr-tb was po...
