This albumin allow us to establish misbalance of albumin content (hypo- and hyperalbuminemia) at various pathologic conditions. Increase of albumin concentration can be noted in case of dehydration. Decrease of concentration SA in case of malnutrition, infringements of resorption, diseases of liver (cirrhosis, atrophy, toxic damage, blastomas). Increased loss of albumin is observed in case of renal syndrome, diseases of gastro-intestinal tract, burns, bleedings, massive effusions (exudates). Increased disintegration of albumin takes place at sepsis, fever, traumas, blastomas.
