All you need to know about pleural fluid sampling

What is Pleural Fluid Sampling?

Sometimes fluid gets accumulated in the space between the lungs and the rib cage or the diaphragm, which may cause some infections or diseases. This is known as pleural effusion and is detected on a chest x-ray. When such a fluid is sampled, it is known as pleural fluid sampling and is important as it allows the doctor to understand the reason behind the accumulation of the fluid and how to treat it. A needle can be used for the process of sampling.

When is Pleural Fluid Sampling recommended?

A pleural fluid sampling is recommended if the symptoms of pleural effusion are observed. The symptoms of pleural effusion include chest pain particularly when breathing in deeply, dry cough, difficulty in breathing, fever, persistent hiccups, difficulty in breathing when lying down, and difficulty in doing physical activities.
