Crystals can be identified based on their appearance and the pH of the urine (many types preferentially form at an acidic or alkaline pH). [123] Crystals that can be found in normal urine include uric acid, monosodium urate, triple phosphate (ammonium magnesium phosphate), calcium oxalate, and calcium carbonate. [124]
Urine electrolyte levels can be measured in a medical laboratory for diagnostic purposes. The urine concentrations of sodium , chlorine and potassium may be used to investigate conditions such as abnormal blood electrolyte levels, acute kidney injury , metabolic alkalosis and hypovolemia .
Urine drug testing is one of the most common testing methods used. The enzyme-multiplied immune test is the most frequently used urinalysis. Complaints have been made about the relatively high rates of false positives using this test. [18] Urine drug tests screen the urine for the presence of a parent drug or its metabolites.
methanol, mainly for the production of formaldehyde and as a fuel additive; ethanol, mainly for alcoholic beverages, fuel additive, solvent, and to sterilize hospital instruments. [26] 1-propanol, 1-butanol, and isobutyl alcohol for use as a solvent and precursor to solvents; C6–C11 alcohols used for plasticizers, e.g. in polyvinylchloride
A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system , and specimens are easy to obtain. [ 1 ]
The holidays are a festive time of year. Homes are decorated for the season — Christmas trees, ornaments, poinsettias, and the like. And there are also plenty of holiday treats that are ...
Hyperchloremic acidosis is a form of metabolic acidosis associated with a normal anion gap, a decrease in plasma bicarbonate concentration, and an increase in plasma chloride concentration [1] (see anion gap for a fuller explanation).
