1. Is anyone at high risk for abnormal albumin levels?
Individuals who have chronic liver disease and kidney disorders are at highest risk for developing abnormal albumin levels. In addition, individuals whose GI tract doesn't absorb nutrients properly and individuals who have prolonged diarrhea can develop abnormal albumin levels.
3. What is the difference between serum/plasma albumin, prealbumin, and urine albumin tests?
Although the names are similar, albumin and prealbumin are completely different molecules. They are both proteins made by the liver, however, and both have been used historically to evaluate nutritional status. Serum/plasma (or blood) albumin is now more often used to screen for and help diagnose liver or kidney disease and is tested on a blood sample. The urine albumin test (in the past, called a microalbumin test) detects and measures albumin in the urine as an early indicator of kidney damage.
