Pericardial fluid Gram stain

Gram stain of pericardial fluid

Pericardial fluid Gram stain is a method of staining a sample of fluid taken from the pericardium. This is the sac surrounding the heart to diagnose a bacterial infection. The Gram stain method is one of the most commonly used techniques to rapidly identify the cause of bacterial infections.

Pericardial fluid stain

Pericardial fluid that is obtained from the heart is stained with a violet stain known as gram stain. The sample is then examined under the microscope for the presence of bacteria. The color, number, and morphologic appearance of the cells help make it possible to identify the organism. The test is performed when an infection of the heart is suspected, or when a pericardial effusion is present.
