1. 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 (also called a microalbumin test) detects and measures albumin in the urine as an early indicator of kidney damage.
2. Is there anything I can do to prevent microalbuminuria?
Yes, if you are diabetic, follow your healthcare provider's instructions for maintaining tight control over your blood glucose level. Keeping high blood pressure under control is also effective in preventing kidney damage that leads to microalbuminuria. Some studies have shown that those who have albuminuria can prevent it from worsening or may reverse it with good glycemic and blood pressure control, or by quitting smoking.
3. Are there other reasons for having increased urine albumin levels?
Yes, albuminuria is not specific for diabetes. It may also be associated with hypertension (high blood pressure), some lipid abnormalities, and several immune disorders. Elevated results may also be caused by vigorous exercise, blood in the urine, urinary tract infection, dehydration, and some drugs.
