A normal albumin level in the blood typically ranges from 3.4 to 5.4 g/dL (grams per deciliter) or 34 to 54 g/L (grams per liter). However, slight variations might occur depending on the laboratory and the specific methods used for measurement. Some labs report a slightly different range, such as 3.5 to 5.5 g/dL.
Understanding Albumin
Albumin is a protein produced by the liver. It's the most abundant protein in your blood and plays a crucial role in maintaining fluid balance, transporting hormones and other substances, and supporting the immune system. Measuring albumin levels helps assess liver and kidney function, as well as overall nutritional status.
Interpreting Albumin Levels
-
Lower-than-normal albumin levels (hypoalbuminemia): This can indicate various health issues, including:
- Malnutrition
- Liver disease
- Kidney disease
- Inflammatory diseases
-
Higher-than-normal albumin levels (hyperalbuminemia): Elevated levels are less common and can be associated with:
- Acute infections
- Burns
- Stress from surgery or a heart attack
Important Note: Always consult your doctor to interpret your albumin test results. The context of your overall health, other test results, and symptoms are essential for proper diagnosis and treatment.
Reference Ranges Across Different Sources
Several sources provide slightly different ranges for normal albumin levels, reflecting variations in laboratory methods and populations studied. The following table summarizes these ranges:
| Source | Normal Albumin Range (g/dL) |
|---|---|
| Multiple Medical Websites | 3.4 - 5.4 |
| Cleveland Clinic | 3.5 - 5.5 |
| Medscape | 3.5 - 5.0 |
| University of Rochester | 3.4 - 5.4 |
| Mount Sinai | 3.4 - 5.4 |
