PARACENTESIS
Usually, abundant fluid _____ is collected; therefore,
suitable specimens are available for each section of the
laboratory.
> 100mL
is used for
cell counts and the differential.
EDTA
evacuated tubes are used for
microbiology and cytology.
Sterile heparinized or SPSS
can be run on clotted specimens in plain tubes or in heparin
tubes.
CHEMISTRY TESTS x PLAIN TUBES OR HEPARIN
Effusions that form because of a systemic disorder that
disrupts the balance in the regulation of fluid filtration and
reabsorption—such as the changes in hydrostatic pressure created
by congestive heart failure or the hypoproteinemia associated with
nephrotic syndrome
TRANSUDATES - systemic and nephrotic syndrome, CHF, hypoproteinemia
produced by conditions that directly involve the
membranes of the particular cavity, including infections and
malignancies.
EXUDATES - infections and malignancies
However, the most reliable
differentiation is obtained by determining the
Fluid blood ratios for protein and lactic dehydrogenase
Cloudy Appearance
EXUDATE
No Spontaneous
clotting
TRANSUDATE
To differentiate between transudates and exudates, two more
procedures are helpful when analyzing pleural fluid:
pleural fluid cholesterol (>60) and fluid:serum
cholesterol (>0.3)
the ratio of pleural fluid:serum total bilirubin. (>0.6)
is recommended only in
effusions suspected of being due to rheumatoid
arthritis.
GLUCOSE
only a small amount (10 to 50 mL) of fluid is found
between the pericardial serous membranes
