-
Immunoassay reagents intended to perform qualitative and/or quantitative analyses on a body fluid sample to determine albumin, the most abundant protein in human plasma. Albumin stores and transports various ligands (e.g., thyroxin, cortisol, aldosterone), maintains oncotic pressure, and serves as a source of endogenous amino acids. Increased albumin levels (hyperalbuminemia) are of little diagnostic value except in dehydration, while decreased levels (hypoalbuminemia) are found in many diseases related to liver function, tissue damage, and/or protein loss in urine and/or feces due to diabetes, burns, neoplasms, or kidney diseases
