Addis Count
The Addis count is a urine test measuring urinary casts over time. It is named for Thomas Addis Thomas Addis Jr. (July 27, 1881 – June 4, 1949) was a Scottish physician-scientist from Edinburgh who made important contributions to the understanding of how blood clots work. He was a pioneer in the field of nephrology, the branch of interna .... References Urine tests {{Med-diagnostic-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urine
Urine is a liquid by-product of metabolism in humans and in many other animals. Urine flows from the kidneys through the ureters to the urinary bladder. Urination results in urine being excreted from the body through the urethra. Cellular metabolism generates many by-products that are rich in nitrogen and must be cleared from the bloodstream, such as urea, uric acid, and creatinine. These by-products are expelled from the body during urination, which is the primary method for excreting water-soluble chemicals from the body. A urinalysis can detect nitrogenous wastes of the mammalian body. Urine plays an important role in the earth's nitrogen cycle. In balanced ecosystems, urine fertilizes the soil and thus helps plants to grow. Therefore, urine can be used as a fertilizer. Some animals use it to mark their territories. Historically, aged or fermented urine (known as lant) was also used for gunpowder production, household cleaning, tanning of leather and dye ...

Urine Test
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. Common urine tests include the routine urinalysis, which examines the physical, chemical, and microscopic properties of the urine; urine drug screening; and urine pregnancy testing. Background The value of urine for diagnostic purposes has been recognized since ancient times. Urine examination was practiced in Sumer and Babylonia as early as 4000 BC, and is described in ancient Greek and Sanskrit texts. Contemporary urine testing uses a range of methods to investigate the physical and biochemical properties of the urine. For instance, the results of the routine urinalysis can provide information about the functioning of the kidneys and urinary system; suggest the presence of a urinary tract infection (UTI); and scre ...

Urinary Casts
Urinary casts are microscopic cylindrical structures produced by the kidney and present in the urine in certain disease states. They form in the distal convoluted tubule and collecting ducts of nephrons, then dislodge and pass into the urine, where they can be detected by microscopy. They form via precipitation of Tamm–Horsfall mucoprotein, which is secreted by renal tubule cells, and sometimes also by albumin in conditions of proteinuria. Cast formation is pronounced in environments favoring protein denaturation and precipitation (low flow, concentrated salts, low pH). Tamm–Horsfall protein is particularly susceptible to precipitation in these conditions. Casts were first described by Henry Bence Jones (1813–1873). As reflected in their cylindrical form, casts are generated in the small distal convoluted tubules and collecting ducts of the kidney, and generally maintain their shape and composition as they pass through the urinary system. Although the most common forms ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Addis
Thomas Addis Jr. (July 27, 1881 – June 4, 1949) was a Scottish physician-scientist from Edinburgh who made important contributions to the understanding of how blood clots work. He was a pioneer in the field of nephrology, the branch of internal medicine that deals with diseases of the kidney. Addis described the pathogenesis of haemophilia in 1911 and was the first to demonstrate that normal plasma could correct the defect in haemophilia. Biography Addis was the son of Thomas Chalmers Addis, a clerk at the local branch of the Inland Revenue Service, and Cornelia Beers-Campbell, who married in Hoboken, New York, in 1880, but he was born in Edinburgh. Significant influences in his childhood were his grandfather, the Rev Dr Thomas Addis DD, Minister at Morningside Free Kirk, and his grandfather's assistant, the Very Rev Dr Alexander Martin (who came to lead the movement within the Free Kirk for reunification with the Established Church of Scotland). Addis studied medicine in his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
