Osmotic diuresis is the increase of urination rate caused by the presence of certain substances in the proximal tubule (PCT) of the kidneys. [2] The excretion occurs when substances such as glucose enter the kidney tubules and cannot be reabsorbed (due to a pathological state or the normal nature of the substance).
A fluid or water deprivation test is a medical test [1] which can be used to determine whether the patient has diabetes insipidus as opposed to other causes of polydipsia (a condition of excessive thirst that causes an excessive intake of water). The patient is required, for a prolonged period, to forgo intake of water completely, to determine ...
The test pad contains a polyelectrolyte that releases hydrogen ions in proportion to the concentration of ions in the sample. The consequent pH change is measured using a pH indicator. The reading obtained from reagent strips, as opposed to refractometers, is not affected by substances such as glucose, urea and contrast dyes. Falsely low ...
A random plasma glucose test, on the other hand, checks your blood glucose levels at any time — regardless of when you last ate. The measurements are the same for both tests. You may need a ...
Many point-of-care test systems are realized as easy-to-use membrane-based test strips, often enclosed by a plastic test cassette. [2] This concept often is realized in test systems for detecting pathogens, the most common being COVID-19 rapid tests. Very recently such test systems for rheumatology diagnostics have been developed, too. [12]
You may need a fluoroscopic swallowing study, which involves eating or drinking while being filmed under x-ray to see how food moves in the mouth and throat, Dr. Nocerino says.
