• Convenient. No extra equipment required.
• Sample treatment and assay can be performed in under 15 minutes.
• Method: Visual
• Samples: Serum, plasma, urine, etc

UREA, the major end product of protein catabolism in animals, is primarily produced in the liver and secreted by the kidneys. It is the primary vehicle for removal of toxic ammonia from the body. Urea determination is very useful for medical clinicians to assess kidney function of patients. In general, increased urea levels are associated with nephritis, renal ischemia, urinary tract obstruction, and certain extrarenal diseases (e.g. congestive heart failure, liver diseases, and diabetes). Decreased levels often indicate acute hepatic insufficiency, but may also result from over vigorous parenteral fluid therapy. BioAssay Systems' QuantiQuik™ Urea (BUN) Test Strips are based on Urease catalyzed conversion of urea to ammonium and carbon dioxide. The pH of the reaction medium is monitored by a chromogen and the intensity of the product color is directly proportional to the urea concentration in the sample. The QuantiQuik™ Urea Test strips allow for rapid and inexpensive quantitative determination of urea or blood urea nitrogen (BUN) and do not require sophisticated laboratory instruments.
