1. What is the difference between prealbumin, serum/plasma albumin, and urine albumin tests?
Although the names are similar, prealbumin and albumin 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.
