Light's Criteria Calculator

A criteria used to distinguish the pleural exudates and transudates is called as the light's criteria. A fluid is said to be exudative if the
1. Effusion fluid / serum protein ratio is greater than 0.5,
2. Effusion LDH / serum LDH ratio is greater than 0.6
3. Effusion LDH level greater than 2/3 of the upper limit of the laboratory reference range of serum LDH.
This online lights criteria calculator is used to find, if a plueral fluid is exudative or not with protein and LDH (Lactate Hydrogenase) parameters.
