Light S Criteria

Light s criteria are nearly 100 percent sensitive at identifying exudates but approximately 20 percent of patients with pleural effusion caused by heart failure may fulfill the criteria for an.

Light s criteria.

Using the patient s blood and the fluid in the effusion and comparing specific characteristic parameters medical practitioners can determine if the fluid is caused by internal pressure problems transudate or cellular leakage exudate. Light s criteria are more accurate for the diagnosis of exudative effusions.

Criteria which help differentiate pleural exudates and transudates light s criteria for exudates any of following pleural fluid serum protein ratio 0 5 pleural fluid serum ldh ratio 0 6 pleural fluid ldh 2 3 the normal upper limit for serum.

The fluid is considered an exudate if any of the following are present. A criteria used to distinguish the pleural exudates and transudates is called as the light s criteria. The light s criteria for exudative effusions determines if pleural fluid is exudative. The light s criteria for exudative effusions determines if pleural fluid is exudative.

Light s criteria is a calculation that helps determine whether fluid within a body cavity called an effusion is caused by transudate or exudate. Light s criteria are highly statistically sensitive for exudates although not very statistically specific. Effusion fluid serum protein ratio is greater than 0 5 2. The ratio of pleural fluid to serum protein is greater than 0 5.

This is an unprecedented time. More recent studies have examined other characteristics of pleural fluid that may help to determine whether the process producing the effusion is local exudate or systemic transudate. The ratio of pleural fluid to serum ldh is greater than 0 6.
