Serum or plasma concentration of albumin (total protein component)
This test measures the amount of albumin, a key protein in your blood that helps maintain fluid balance and supports immune function.
["Albumin helps keep tissues hydrated and supports immune health; low levels may signal kidney issues or malnutrition."]

Why Albumin Levels Matter
Albumin is vital for transporting nutrients, hormones, and medications in your blood. It also helps maintain blood pressure and prevents fluid from leaking out of blood vessels. Low albumin can indicate problems like kidney disease, liver problems, or poor nutrition, while high levels may suggest dehydration or certain medical conditions.
What Can Affect Albumin Levels?
Several factors can influence albumin levels, including diet (low protein intake), chronic diseases (like kidney or liver disease), infections, or medications. Stress, pregnancy, or certain medical treatments may also play a role.
Common Causes of Abnormal Results
Low albumin levels may be linked to conditions such as chronic kidney disease, liver cirrhosis, severe infections, or malnutrition. High albumin levels can sometimes result from dehydration or certain inflammatory responses, though they’re less common.
Clinical Significance
Albumin is often checked alongside other blood tests to assess overall protein status and identify underlying health issues. It can help doctors diagnose or monitor conditions affecting fluid balance, immune function, or organ health.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Albumin levels are important for diagnosing and managing conditions like protein-losing syndromes, malnutrition, or chronic diseases. Doctors may use these results to guide treatment plans, such as dietary adjustments or medical interventions for kidney or liver issues.
