Which lab test is commonly used to monitor protein levels in patients?

Serum albumin is widely recognized as a key laboratory test for monitoring protein levels in the body. This is largely due to albumin being the major protein found in the blood, which plays critical roles in maintaining oncotic pressure and transporting various substances. Its levels can give insights into nutritional status, liver function, and other health issues. When a patient has low serum albumin levels, it can indicate inadequate protein intake, protein loss due to kidney disease, or liver dysfunction, among other conditions.

In practical terms, healthcare professionals often assess serum albumin as part of a comprehensive evaluation of a patient's nutritional status, particularly in conditions where malnutrition or protein status is a concern, such as chronic illness or post-surgery. Monitoring serum albumin can therefore help determine the effectiveness of dietary interventions or other treatments aimed at improving protein levels.
