Albumin
Stomach and gut healthThe most abundant protein in blood plasma, produced by the liver.
In kidney contexts, low levels in blood may indicate protein loss through damaged kidneys, while presence of albumin in urine (albuminuria) is an important marker of kidney damage.
Why this matters
Low albumin provides early warning of kidney disease (protein loss in urine), liver dysfunction (decreased production), malnutrition, or chronic inflammation. Early signs include subtle ankle swelling, morning puffiness around eyes, foamy urine, or unexplained fatigue. Since albumin takes 20 days to replenish, levels reflect longer-term health status. Optimizing protein intake, managing underlying conditions, and maintaining liver and kidney health can help preserve normal albumin levels.
How this connects to other biomarkers
- Low Albumin with elevated Bilirubin, total and rising Fibrose-Score (FIB-4) suggests the liver is losing its ability to make proteins (worsening cirrhosis).
- Low Albumin with protein in the urine, swelling, and high cholesterol points to nephrotic syndrome (a kidney disease) — correlate with Creatinine.
- Low Albumin with high hs-CRP and elevated Erythrocyte Sedimentation Rate reflects active inflammation rather than true synthesis failure (the body lowers Albumin during inflammation).
- The Albumin/Globulin (A/G) Ratio falls early in monoclonal gammopathies (abnormal plasma cells producing one type of antibody) — if low with positive Immunofixation / Immunotyping, consider plasma cell disease such as multiple myeloma.
