The following are not normally found in urine:Hemoglobin.Nitrites.Red blood cells.White blood cells.
Substances NOT Normally Found in Urine:Glucose.Blood proteins.Red blood cells.Hemoglobin.White blood cells (pus)Bile.
It consists of water, urea (from amino acid metabolism), inorganic salts, creatinine, ammonia, and pigmented products of blood breakdown, one of which (urochrome) gives urine its typically yellowish colour.
Ordinarily, urine contains no glucose because the kidneys are able to reabsorb all of the filtered glucose from the tubular fluid back into the bloodstream. Glycosuria is nearly always caused by elevated blood glucose levels, most commonly due to untreated diabetes mellitus.
Protein is present in the blood; healthy kidneys should only filter tiny (trace) amounts into the urine as most protein molecules are too large for the filters (glomeruli). It is not usual to lose protein in the urine. When this does happen it is known as 'Proteinuria'.
As nutrients like glucose are very useful for the body, glucose is reabsorbed as well. Glucose is therefore not usually found in the urine of a healthy person. With this information, we can exclude answer option (C). This leaves us with the answer option (D), sodium.
Substances normally found in urine are nitrogenous wastes, water, various ions (always including sodium and potassium). Substances normally absent from urine include glucose, blood proteins, blood, pus (WBCs), and bile. The ureters are slender tubes that conduct urine by peristalsis from kidney to bladder.
Low levels of protein in urine are typical. Temporarily high levels of protein in urine aren't unusual either, particularly in younger people after exercise or during an illness. Persistently high levels of protein in urine may be a sign of kidney disease. There is a problem with information submitted for this request.
Normal Results Glucose is not usually found in urine. If it is, further testing is needed. The examples above are common measurements for results of these tests.
Which of the following substances is not normally found in filtrate? Both blood cells and large particles, such as proteins, are not allowed to filter through a healthy glomerular membrane.
Secretion involves the transfer of hydrogen ions, creatinine, drugs, and urea from the blood into the collecting duct, and is primarily made of water. Blood and glucose are not normally found in urine.
Glucose is not normally found in the urine because it (a) does not pass through the walls of the glomerulus, (b) is kept in the blood by colloid osmotic pressure, (c) is reabsorbed by the tubule cells, (d) is removed by the body cells before the blood reaches the kidney.
