Simplified Proteinuria Assessment for Preeclampsia Diagnosis

Rather than a 24-hour urine collection to measure proteinuria, a 12-hour urine protein determination and the protein:creatinine ratio can be used to evaluate suspected preeclampsia. Reuters Health I...

A Simple Urine Test Could Be Used To Calculate How Long A Person Will Live

Researchers have discovered a novel way of finding out how much longer a person will live, by calculating the levels of protein in urine with a simple urine test. The findings, which were published...

Simplified proteinuria assessment reliable for preeclampsia diagnosis

NEW YORK (Reuters Health) - Rather than a 24-hour urine collection to measure proteinuria, a 12-hour urine protein determination and the protein:creatinine ratio can be used to evaluate suspected...

Iodine and creatinine testing in urine dried on filter paper.

Iodine deficiency is a world-wide health problem. A simple, convenient, and inexpensive method to monitor urine iodine levels would have enormous benefit in determining an individual's recent iodine i...

Pediatric normative data for urine NGAL/creatinine ratio.

AIM: The objective of this study was to establish age-dependent urine NGAL (neutrophil gelatinase associated lipocalin) /creatinine ratio values in healthy children and adolescents. METHODS: The study...

Biological monitoring for exposure to deltamethrin: A human oral dosing study and background levels in the UK general population.

An oral dose of the pyrethroid insecticide deltamethrin was administered to five volunteers at the acceptable daily intake (ADI, 0.01mg/kg). Total urine was collected from the volunteers at timed inte...

Determination of uric acid and creatinine in human urine using hydrophilic interaction chromatography.

Uric acid is the end-product of purine metabolism and a major antioxidant in humans. The concentrations of uric acid in plasma and urine are associated with various diseases and routinely measured in...

Distribution pattern of urine albumin creatinine ratio and the prevalence of high-normal levels in untreated asymptomatic non-diabetic hypertensive patients.

Background Even high-normal albuminuria is reportedly associated with cardiovascular events. Objective We determined the urine albumin creatinine ratio (UACR) in spot urine samples and analyzed the UA...
