Protein, Total, Body Fluid
Use
Evaluate effusions; diagnose transudate versus exudate
Special Instructions
Ensure the body fluid specimen is collected in a clean container and labeled correctly with the patient's full name and the type of fluid collected. The usual aseptic aspiration procedure for obtaining body fluid should be followed to prevent contamination. Proper labeling and handling are crucial to prevent errors that could lead to specimen rejection and necessitate repeat collection.
Limitations
The method performance specifications have not been established for protein measurement in body fluids, which means caution should be exercised when interpreting the results. The results need to be integrated with the clinical context for accurate diagnosis. Additionally, the volume of the specimen is limited, and if only the minimum volume is available, repeat testing might not be possible. The stability of samples is dependent on proper storage conditions, limiting the time window for valid testing results.
