Albumin is a protein which is made mainly in the liver. It helps to exert the osmotic pressure which holds water within the blood. It also helps carry nutrients and medications and other substances through the blood and is important for tissue growth and healing. Albumin also carries hormones around the body, therefore measuring the amount of albumin in the blood can help us calculate how much hormone is available to your tissues.

What might a low result mean?

Low albumin levels can indicate liver disease and can also be a marker for chronic ill-health, malnutrition and inflammation. Low levels can also occur in kidney conditions such as nephrotic syndrome as well as diabetes.

What might a high result mean?

Raised levels are usually caused by dehydration, however elevated levels of albumin can also appear in malnutrition, inflammatory conditions, as well as kidney and heart conditions.
