Fluid Albumin measurement is essential for calculating the Serum-Ascites Albumin Gradient (SAAG). This calculation (Serum Albumin minus Fluid Albumin) is the gold standard for determining if fluid accumulation (ascites or pleural effusion) is due to portal hypertension (transudate) or other causes like malignancy or infection (exudate).

Why Context Matters

Fluid albumin must be measured simultaneously with serum albumin for accurate gradient calculation. Recent IV fluid administration or diuretics can skew results.

Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
