WebDec 1, 2008 · Acute dehydration biochemically manifests itself with mild uremia and a normal creatinine concentration. The reason for this, as quoted in popular medical textbooks, is that there is increased reabsorption of urea by the kidneys ().This explanation is rarely taken further by clinical tutors or lectures on laboratory medicine.
WebFeb 1, 2001 · Creatinine clearance has been used for many decades to estimate GFR. It involves a 24-hour urine collection to measure creatinine excretion. As the same sample can be used to measure the protein excretion rate, creatinine clearance is often used for the initial evaluation of renal diseases, such as glomerulonephritis. WebRecall that substances that need to be removd from the body but were not yet filtered, can be secreted. This reabsorption occurs in the PCT, loop of Henle, DCT, and the collecting ducts while the majority of secretion …
WebMay 19, 2024 · BUN-to-creatinine ratio is the ratio of two serum laboratory values, the blood urea nitrogen (BUN) (mg/dL) and serum creatinine (Cr) (mg/dL).The principle behind this ratio is the fact that both urea (BUN) and creatinine are freely filtered by the glomerulus; however, urea reabsorbed by the tubules can be regulated (increased or decreased) … WebJan 17, 2024 · The substance that remains in the collecting duct of the kidneys following reabsorption is better known as urine.
