Flashcards in Other Body Fluids Deck (25):
when is a paracentesis performed?
excessive volume to relieve abdominal pressure
evaluate post trauma injuries
prefix for "not enough"
what is the purpose of the diagnostic paracentesis?
differentiate between transudative (< 3g of protein) and exudative (>3 g of protein)
determines the cause of the effusion (what kind of fluid is it?)
what is a transudative fluid?
from another organ
(SAAG >1.1, but otherwise normal values)
what is the exudative fluid?
pus or secretion, infectious process
(high protein SAAG <1.1, high WBC, low glucose, high LD, cloudy)
what is the serum ascitic albumin gradient?
Albumin Conc of serum - albumin conc of ascitic fluid = SAAG
SAAG >1.1 g/dL is
SAAG <1.1 g/dL is
what are causes of transudative
portal vein thrombosis
what are causes of exudative
inflammation of pancreas
ischemic or obstructed bowel
high ammonia and alkaline phosphotase indicates
spontaneous bacterial peritonitis
infection of ascitic fluid only
usually in patients with chronic liver disease due to translocation of enteric bacteria
do not do it, not matter what
-acute abdomen requiring surgery
may or may not want to do the procedure depending on pt situation
performed to determine the cause of an unexplained pericardial effusion
also to relieve intrapericardial pressure
when would you perform sweat analysis?
what is a potential complication of a pericardialcenthesis
how would you diagnose spontaneous bacterial peritonitis?
>50% of PMNs in fluid
what is an absolute contraindicatino for pericardiocentesis?
none if hemodynamically unstable
what is the sweat analysis test called?
quantitative pilocarpine iontophoresis test (QPIT)
what is the gradient for the sweat test results?
>60 = diagnosis
what is the newborn screening test for CF?
what is normal sperm count?
what is normal semen volume?
