Albumin [Presence] in Urine by Test strip

Active

Part Description

LP6118-6   Albumin
A non-glycosylated protein that is synthesized in the liver parenchymal cells, regulated by colloid osmotic pressure from interstitial fluid surrounding hepatocytes, and catabolized in nearly all organs. Albumin comprises >50% of plasma proteins in plasma, CSF and urine, and therefore is a key contributor to intravascular oncotic pressure and regulating fluid concentration in tissues. Albumin also binds and transports a variety of endogenous substances and medications. Serum albumin measurement is a reflection of hydration and nutritional status, blood oncotic pressure, liver and kidney function, and other chronic diseases, and the ratio of albumin in the CSF and serum can be used to evaluate blood brain barrier disorders. [Tietz] Urine albumin of less than 30 mg/day is considered normal. Microalbuminuria is defined as urine albumin of 30-300 mg/day and is an early sign of kidney damage from disorders such as diabetes or hypertension. Albuminuria is urine albumin >300 mg/day and is associated with overt kidney disease. PMID: 25512779 Source: Regenstrief LOINC

Last Updated

Version 2.77 (MAJ)

Change Reason

Release 2.77: SCALE_TYP: Updated the Scale back to Ord as these were inadvertently set to SemiQn during the 2.75 release when we added SemiQn.; Previous Releases: The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
