Fluid Albumin

A fluid albumin test is advised by a doctor when there is an abnormal fluid buildup, such as ascites (abdominal fluid) or pleural effusion (fluid around the lungs). It helps identify the cause, such as cirrhosis, heart failure, tuberculosis, or cancer, and is done alongside serum albumin to calculate the albumin gradient.

A fluid albumin test requires a fluid sample collected by a doctor through paracentesis (abdominal fluid) or thoracentesis (pleural fluid). Inform your doctor about any blood thinners, allergies, bleeding disorders, or pregnancy. Fasting is usually not required. A blood sample for serum albumin is taken at the same time to calculate the gradient.

No, fasting is usually not required for a fluid albumin test. You can eat and drink normally unless your doctor advises otherwise, for example if sedation is planned for the fluid collection procedure. Inform your doctor about any blood thinners or bleeding disorders, and follow the hospital's specific instructions.
