Albumin Blood Test
The Albumin Blood Test measures the most abundant protein in your blood. Produced by the liver, albumin helps maintain fluid balance, transports nutrients and hormones, and contributes antioxidant activity. Levels may fall with inflammation, infection, nutritional deficiencies, or liver/kidney disease, and naturally decline with age. As part of the PlexusDx Nutrition Deficiency Blood Test, albumin offers useful context for overall nutritional status and systemic health.
Why Measure Albumin?
- Nutritional insight: Low albumin can reflect inadequate protein or calorie intake.
- Liver & kidney context: Albumin is synthesized in the liver and lost in some kidney conditions.
- Inflammation signal: Systemic inflammation often suppresses albumin production.
How the PlexusDx Test Works
- At-home collection: Quick finger-prick kit with prepaid return mailer.
- Fast turnaround: Digital results typically ~2 business days after the lab receives your sample.
- Direct access & HSA/FSA: Order online; HSA/FSA accepted.
Understanding Results
Providers interpret albumin alongside other findings (e.g., ferritin, hematocrit, medical history) to determine whether nutrition, inflammation, or organ function is the primary driver.
What Can Influence Albumin?
- Inflammation, infection, liver or kidney disease.
- Hydration status and overall protein intake.
- Aging and acute illness or surgery.
