Albumin is a protein made by the liver that plays an important role in many bodily functions, including:

• Maintaining fluid balance in your body
• Transporting hormones, vitamins, and other substances throughout your bloodstream
• Helping fight infections

Serum albumin testing has a wide range of clinical interests, including:

• Liver disease: Low albumin levels can be a sign of liver damage or disease.
• Kidney disease: Albumin can leak into the urine in people with kidney disease. This can lead to low albumin levels in the blood.
• Malnutrition: People who are malnourished often have low albumin levels.
• Inflammation and infection: These can cause the liver to produce less albumin.

In addition to the conditions listed above, serum albumin levels may also be abnormal in people with Cancer, Burns, Trauma, Heart failure and Autoimmune diseases
