In biliary obstruction, below-normal amounts of conjugated bilirubin reach the intestine for conversion to urobilinogen. With limited urobilinogen available for reabsorption and excretion, the amount of urobilin found in the urine is low. High amounts of the soluble conjugated bilirubin enter the circulation where they are excreted via the kidneys.
The normal number of red blood cells in urine should not usually exceed 3 per high power field. [13] A urine test strip showing positive for blood can also indicate hemoglobinuria, which is not detectable using a microscope due to the lysis of red blood cells in the urinary tract (particularly in alkaline or dilute urine), or intravascular ...
In bile duct obstruction, urine bilirubin increases but urobilinogen is normal or decreased, as bilirubin cannot reach the intestines to be converted to urobilinogen. [85] Testing methods are based on the Ehrlich reaction of urobilinogen with para-dimethylaminobenzaldehyde, or interaction with a diazonium compound to produce a colored product.
Hyperuricosuria is a medical term referring to the presence of excessive amounts of uric acid in the urine. For men this is at a rate greater than 800 mg/day, and for women, 750 mg/day. [ 1 ] Notable direct causes of hyperuricosuria are dissolution of uric acid crystals in the kidneys or urinary bladder , and hyperuricemia .
John McCain suffers from a highly malignant form of cancer that spreads quickly due to its association with a large network of blood vessels in the brain.
Uric acid is a product of the metabolic breakdown of purine nucleotides, and it is a normal component of urine. [1] High blood concentrations of uric acid can lead to gout and are associated with other medical conditions, including diabetes and the formation of ammonium acid urate kidney stones .
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]
