About the product
ALB2 (Albumin Gen.2) is an in vitro diagnostic reagent from Roche Diagnostics for albumin measurement. According to Roche’s product page, the test is for the quantitative determination of albumin in human serum and plasma and is used on cobas c and COBAS INTEGRA systems.
The product is part of the Roche Diagnostics test kit range supplied by Tilia Medical.
Measured parameter and clinical significance
Albumin is a protein made by the liver. According to MedlinePlus, it keeps fluid from leaking out of blood vessels and carries substances such as hormones, vitamins and enzymes through the body.
The albumin test is used to assess general health and nutritional status and liver and kidney function; it is often requested as part of liver function tests or the comprehensive metabolic panel. According to MedlinePlus, low levels may point to liver or kidney problems and malnutrition, and high levels may point to fluid loss. The test alone does not establish a diagnosis.
MedlinePlus notes that the albumin test is also requested to evaluate signs of liver or kidney disease such as swelling, jaundice or fatigue, and to monitor treatment of these conditions.
