Waxy casts are broad casts, which is a more general term to describe the wider cast product of a dilated duct, and are seen in chronic kidney failure. In nephrotic syndrome, many additional types of casts exist, including broad and waxy casts if the condition is chronic (this is referred to as a telescopic urine with the presence of many casts ...
Macroscopic examination targets parameters such as color, clarity, odor, and specific gravity; urine test strips measure chemical properties such as pH, glucose concentration, and protein levels; and microscopy is performed to identify elements such as cells, urinary casts, crystals, and organisms.
The presence of "muddy brown casts" of epithelial cells found in the urine during urinalysis is pathognomonic for ATN. [3] Management relies on aggressive treatment of the factors that precipitated ATN (e.g. hydration and cessation of the offending drug).
Urinalysis - After the patient provides a urine specimen, it is sent to the lab for analysis using a variety of methods including urine dipstick testing and microscopic examination. Because the kidney is responsible for making urine, analyzing the urine directly can provide crucial data that can help the physician diagnose nephritic syndrome. [33]
Hair casts, also known as pseudonits, represent remnants of the inner root sheath, and often occur in great numbers and may mimic nits in the scalp. [ 1 ] : 764 Signs and symptoms
Treatment Corticosteroids Rapidly progressive glomerulonephritis ( RPGN ) is a syndrome of the kidney that is characterized by a rapid loss of kidney function, [ 4 ] [ 5 ] (usually a 50% decline in the glomerular filtration rate (GFR) within 3 months) [ 5 ] with glomerular crescent formation seen in at least 50% [ 5 ] or 75% [ 4 ] of glomeruli ...
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 ]
It is also used by employers, who test their employees. [6] Hair analysis has the virtue of showing a 'history' of drug use due to hair's slow growth. Urine analysis might detect drugs taken in the past 2–3 days; hair analysis can sometimes detect use as far as 90 days, although certain cosmetic treatments (e.g. dyeing hair) can interfere ...
