Proteins (Pleural Fluid)

This test measures the levels of proteins in pleural fluid. Proteins are important for various bodily functions, including maintaining fluid balance, transporting substances, and supporting immune function.

This test has multiple uses, including:

• Detecting infections or inflammatory conditions in the lungs
• Evaluating certain lung diseases
• Assessing response to treatment and disease progression

Your doctor may recommend the Proteins (Pleural Fluid) test if you have:

• Symptoms such as chest pain, shortness of breath, or persistent cough
• A diagnosis of lung infection or inflammation
• Undergone a lung biopsy or thoracentesis procedure
• Any condition requiring monitoring of lung health

The reference range for protein levels in pleural fluid has not been established. Abnormal results may indicate infections, inflammation, cancer, or other lung diseases. However, abnormal results require further evaluation and should be interpreted by your doctor in conjunction with your medical history and other tests.

• A small amount of pleural fluid (2 ml) will be collected from your chest using a procedure called thoracentesis.
• The sample will be sent to the laboratory for testing using biochemical methods.
• Results will be available approximately 6 hours after the test.

Before the test, you may need to:

• Fast for a few hours prior to the test as advised by your doctor
• Inform your doctor about any medications or supplements you are taking, as they may interfere with the test results
• Follow any specific instructions provided by your doctor

• Cell count and differential: Determines the types and amounts of cells present in pleural fluid
• Microbiology culture: Identifies any infectious organisms in the pleural fluid.
• Cytology: Examines cells obtained from the pleural fluid to detect cancerous or abnormal cells

Pleural Fluid Protein level test

Pleural effusion is a condition in which an abnormal amount of fluid accumulates between the layers of tissue that line the lungs and chest cavity. It can be caused by various conditions, such as infections, inflammation, heart failure, or cancer. Pleural fluid analysis helps diagnose and monitor pleural effusion.
