ALBUMIN - (P)
Test Code: AL
Albumin constitutes about 60% of the total serum protein in normal, healthy adults. It serves a number of functions, which include transport of large insoluble organic anions (e.g. long chain fatty acids and bilirubin), binding of toxic heavy metal ions, transport of excess quantities of poorly soluble hormones (e.g. cortisol, aldosterone and thyroxine), maintenance of serum osmotic pressure, and provision of a reserve store of protein.
