Body Fluids Flashcards
What are some functions of CSF?
Physical support/protection
control environment/remove waste
transport
T/F CSF usually is done with a lumbar puncture around L3/L4
true, it is usually clear and colorless
What is the order of tubes?
1 chem
2 micro
3 heme
4 extra
Describe xanthochromia
yellow color due to an older bleed
How do you distingush between a traumatic tap and hemorrhage
amount of blood
clot presense
centrifuge
What are some biochemical markers
glucose, protein, lactate, glutamine
(centrifuge samples)
Describe Glucose in CSF
what type of transport
how many hours prior
facillitate transport downhill
2-4 hrs prior
increased is not clinically significant >600
Descrease glucose causes what disorders
disorders in metabolism carriers
ex. bacteria/tumors
T/F: Consumption of glucose decreases lactate and anerobic glycolysis
false, increases lactate and anaerobic glycolysis
Protein in CSF
whatkind of infiltrate
Decrease of Protein is caused by ___
Increased protein caused by ___
selective ultra infiltrate + serum analysis
Dec of prt: dialysis
protein loss
leakage
Incr Prt: lysis of contam blood
permeability
obstruction
T/F: Leakage ID of CSF is used with B- transferrin and CSF and more preAlB than serum
true
T/F: the blood brain barrier is less permeable from bacteria and is diagnostic of infections w meningitis
false, it is more permeable with bacteria and not diagnostic of meningitis
Can ALB cross the BBB?
IgG?
What is the value for intact BBB
Yes, it can cross the bbb,
IgG can not
intact BBB is <9
What is the IgG index used for? what is its range?
Index used for diagnosis of demyelinating diseases like MS
<0.73
T/F: CSF electrophoresis is used for suspected MS
true
T/F: Increase serum ALB = Icreased CSF levels
true
