Lactate Dehydrogenase (LDH), Pleural Fl

This test measures the levels of lactate dehydrogenase in pleural fluid. This test helps evaluate the functioning of cells and identifies abnormal levels of LDH.

This test is mainly done to diagnose and monitor various health conditions, including:

• Pleural effusion (accumulation of fluid in the pleural space)
• Pneumonia (infection in the lungs)
• Lung cancer
• Tuberculosis
• Heart failure
• Autoimmune disorders

Your doctor may recommend this test if you have:

• Symptoms such as shortness of breath, chest pain, or persistent cough
• Been diagnosed with a lung infection or cancer
• A history of autoimmune disorders or heart failure
• Risk factors for certain conditions, such as exposure to asbestos or a family history of lung disease

The reference range for LDH levels in pleural fluid has not been established. Elevated LDH levels may indicate various conditions, including infections, cancers, and heart failure. However, abnormal results do not confirm a diagnosis on their own. You should discuss your test results with your doctor, who will interpret them in the context of your medical history and other diagnostic tests.

• Your doctor will extract pleural fluid from your chest using a small needle.
• A local anaesthetic may be used to numb the area before the procedure.
• The extracted fluid will be sent to a laboratory for testing.
• The laboratory will use an enzymatic method to measure LDH levels in the pleural fluid.

• Inform your doctor about any medications or supplements you are taking.
• Follow any specific instructions provided by your doctor.
• Wear loose and comfortable clothing that allows easy access to your chest area.

• Chest X-ray: This imaging test helps evaluate the structures and organs in your chest, including the lungs and pleural space.
• Pleural fluid analysis: This test examines the fluid extracted from the pleural space to determine the cause of pleural effusion or infection.

Pleural Fluid LDH test

Pleural effusion is a condition characterised by an abnormal accumulation of fluid in the pleural space, which is the space between the layers of tissue that line the lungs and chest cavity. It can be caused by various conditions, including infections, heart failure, and cancer. Pleural fluid analysis, including LDH measurement, helps diagnose and monitor pleural effusion.
