|Why is this test done?||Blood albumin level is used to help diagnose various health problems that involve the kidneys or the liver, for example. It is part of the evaluation of chronic inflammatory disorders as well as infections, diabetes and other illnesses. It can be used to identify cases of malnutrition and dehydration.|
|How to prepare:||
|Associated Tests:||Other blood proteins can be measured at the same time, such as prealbumin, alpha-globulins, beta-globulins or gamma-globulins. Urine albumin levels can also be measured. Liver tests are often performed at the same time.|
Albumin is the most abundant blood protein. It is produced in the liver and plays several roles. It is responsible for maintaining arterial pressure, by keeping water in the blood vessels. It transports several substances, from various hormones to several drugs. Changes in albumin level can be quantitative (decreased or increased level) or qualitative (alteration of the protein itself). Decreased blood albumin levels often result in oedema.
If the result is too high
Increased levels are seen when blood is too concentrated, as is the case with dehydration.
If the result is too low
Reduced liver production or increased albumin losses usually explain low albumin levels. Decreased levels are often associated with inflammatory processes or undernutrition. Liver or kidney problems can also explain abnormally low results.
Pregnancy and taking oral contraceptives ("the pill") as well as blood dilution can lower results. Poor diet can also explain lower results.
Before going for blood tests, a procedure or other exam, it is best to always bring a list of all the drugs you take (prescription, OTC and natural health products). Unless told otherwise, you should take your medication as usual on the day of the test. When in doubt, ask your pharmacist for more information.
