creatinine

Examples of creatinine in the following topics:

• Renal Disease and Failure

  • Renal failure uremia is a syndrome of renal failure characterized by elevated levels of urea and creatinine in the blood.
  • This is detected by a decrease in or absence of urine production or determination of waste products (creatinine or urea) in the blood.
  • Renal failure can be divided into two categories: acute kidney injury or chronic kidney disease .The type of renal failure is determined by the trend in the serum creatinine.
  • Renal failure uremia is a syndrome of renal failure that includes elevated blood urea and creatinine levels.
  • Diagnostic tests include BUN and plasma creatinine level tests.

• Tubular Secretion

  • Hydrogen, creatinine, and drugs are removed from the blood and into the collecting duct through the peritubular capillary network.
  • At this final stage it is only approximately one percent of the originally filtered volume, consisting mostly of water with highly diluted amounts of urea, creatinine, and variable concentrations of ions.

• Chemical Composition of Urine

  • The normal chemical composition of urine is mainly water content, but it also includes nitrogenous molecules, such as urea, as well as creatinine and other metabolic waste components.

• Edema Caused by Loss of Plasma Proteins

  • Microalbuminuria between 30 and 300 mg/24h, mg/l of urine or µg/mg of creatinine can be a forerunner of diabetic nephropathy.

• Diagnostic Blood Tests

  • A basic metabolic panel measures sodium, potassium, chloride, bicarbonate, blood urea nitrogen (BUN), magnesium, creatinine, glucose, and sometimes includes calcium.

• Pulmonary Edema

  • Blood tests are performed for electrolytes (sodium, potassium) and markers of renal function (creatinine, urea).

• Overview of Urine Formation

  • During secretion some substances±such as hydrogen ions, creatinine, and drugs—will be removed from the blood through the peritubular capillary network into the collecting duct.

• Acidosis

  • Renal acidosis is associated with an accumulation of urea and creatinine as well as metabolic acid residues of protein catabolism.

• Dialysis

  • The counter-current flow of the blood and dialysate maximizes the concentration gradient of solutes between the blood and dialysate, which helps to remove more urea and creatinine from the blood.

• Placenta

  • Waste products excreted from the fetus—urea, uric acid, and creatinine—are transferred to the maternal blood by diffusion across the placenta.
