Fluid Total Protein
- Sample Type
- Standard
- Fasting
- No
- Unit
- g/dL
Fluid Total Protein is a critical parameter in the biochemical analysis of effusions (pleural, ascitic, or pericardial). It is used to categorize the fluid as either a 'transudate' (low protein) or an 'exudate' (high protein). Transudates are typically caused by systemic pressure changes (e.g., heart failure), while exudates result from local disease causing capillary permeability (e.g., infection or malignancy).

Why Context Matters
In patients on chronic diuretic therapy, a transudate (like in heart failure) can 'concentrate' and show high protein levels, mimicking an exudate. Clinical correlation using Light's Criteria (comparing fluid protein to serum protein) is essential for accuracy.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
