The modified Light's criteria should be used to classify the fluid as either an exudate or a transudate
Although a number of tests have been proposed to differentiate pleural fluid transudates
from exudates, the tests first proposed by Light et al have become the criterion standards.
Objective: Light's criteria, which were accepted in 1972 for the differential diagnosis of pleural effusions as transudates
or exudates, are widely used worldwide.
are pale yellow and hazy to cloudy depending on the number of cells present.
Some specific conditions associated with transudates
are: Congestive heart failure--Fluid usually straw colored, with low white blood cell counts (< 500 cells/mm3) and a mononuclear cell predominance.
Results of cytologic evaluation, specific gravity analysis, and aerobic bacterial culture of the coelomic fluid yielded consistent results of a pure to modified transudate
with no evidence of infection.
5) and deionised water is approved for use in humans by the USA's Food and Drug Administration (FDA) and is licensed for collection of oral mucosal transudate
(OMT) for anti-HIV testing.
Eustachian tube dysfunction leads to negative pressure in the middle ear causing a transudate
from the middle ear mucosa to accumulate in the middle ear space.
Whether a pleural effusion is a transudate
or an exudate depends on the underlying disease process causing the abnormal fluid accumulation.
Pharmacokinetics and pharmacokinetic/pharmacodynamic integration of marbofloxacin in calf serum, exudate and transudate
Indeed this should be expected given the evidence that HIV-1 antibody testing of oral mucosa transudate
samples is a highly accurate alternative to serum testing.
A Measurement of total protein in body fluids other than blood, urine, or cerebrospinal fluid is usually done to differentiate an inflammatory fluid collection, an exudate, from one that is not inflammatory, a transudate
