Pleural Fluid Labs. A pleural fluid ada level greater than 40 u per l 667 nkat per l has a sensitivity of 90 to 100 percent and a specificity of 85 to 95 percent for the diagnosis of tuberculous pleurisy. Lab studies pleural fluid lactate dehydrogenase. Thoracoscopy is a minimally invasive technique also known as video assisted thoracoscopic surgery or vats performed under general anesthesia that allows for a visual evaluation of the pleura. Lights criteria high protein and ldh exudate determines presence of exudate with protein and ldh levels.
The first section of this topic is shown below synonym acronym. This gliding movement helps with normal breathing. A thoracentesis is a procedure used to drain excess fluid from the space. Microscopic examination a laboratory professional may place a sample of the fluid on a slide and examine it under a microscope. When the pleural effusion has remained undiagnosed despite previous less invasive tests thoracoscopy may be performed. Lights criteria high protein and ldh exudate determines presence of exudate with protein and ldh levels.
Pleural fluid ldh levels are also increased in effusions from pneumocystis jiroveci previously called p carinii pneumonia.
Transudate is due to congestive heart failure nephrotic syndrome hypoproteinemia and cirrhosis. Lab studies pleural fluid lactate dehydrogenase. Other conditions like collagen diseases trauma pulmonary infarction and drug hypersensitivity may cause exudate. Pleural fluid ldh to serum ldh ratio 0 6. Pleural fluid laboratory findings. Pleural fluid ldh levels are also increased in effusions from pneumocystis jiroveci previously called p carinii pneumonia.
