Albumin

Individuals who have chronic liver disease and kidney disorders are at highest risk for developing abnormal albumin levels.  In addition, individuals who have an inflammatory condition of any sort or who have prolonged diarrhoea can develop abnormal albumin levels.

The prealbumin test measures a protein that in part reflects your nutritional status and can be useful to measure in individuals receiving nutritional support. Albumin testing is more often used to test for liver or kidney disease or to provide information on the severity of an inflammatory disorder.  The blood prealbumin level falls in response to malnutrition, making it of some value in detecting changes in nutritional status but like albumin its blood level also falls in individuals who have liver disease or inflammatory disorders. The microalbumin test measures very small levels of albumin in your urine and may indicate whether you are at risk for developing kidney disease.
