Believe it or not, your urine actually reveals quite a bit about your diet and health, so kudos to you for asking the question! While it?s hard to determine the cause of, and remedy for, your dark brown smelly pee, there are a number of factors which can potentially alter urine color and smell. Some causes may be benign, while others indicate more serious health conditions (more on those in a b...

Purple urine bag syndrome is a rare condition in which purple discoloration of urine inside its collection bag occurs. We describe two illustrative cases. The first patient is an 81-year-old man who was hospitalized for a newly diagnosed lymphoma with acute obstructive renal failure for which a nephrostomy procedure was performed. During the hospitalization, a sudden purple discoloration of the...

Previous studies (1, 2) have shown that after the ingestion of caffeine or theophylline by man there was an increased urinary excretion of material which gave a blue color with the alkaline arsenophosphotungstate reagents used in the determination of uric acid. Myers and Wardell (3) and Buchanan, Christman, and Block (1) presented evidence that this extra color was caused by methyluric acids ra...

The first step in curing a disease is being able to detect the disease effectively. Paper-based microfluidic devices are biodegradable and can make diagnosing diseases cost-effective and easy in almost all environments. We created a three-dimesnional (3D) paper device using wax printing fabrication technique and basic principles of origami. This design allows for a versatile fabrication techniq...

An automated method for estimation of methylmalonic acid in urine is described that compares well with results obtained by a manual method. The temperature at which color is developed can be set anywhere between ambient and 90°C without loss of linearity over a certain range of concentrations. The higher temperatures have greater sensitivity but a smaller linear range than do lower incubation-t...

The recent trials of gentisic acid as a therapeutic agent (1, 2)’ stimulated our interest in the development of methods for the determination of gentisic acid in serum. Meyer and Ragan (1) referred to a method which is suitable for the analysis of gentisic acid in urine. No details were given. Although they were able to detect 5 y of hydroquinone per ml. in urine (l), they did not find detectab...
