HEMA LAB - ESR Flashcards
speed of settling of RBC in anticoagulated blood
esr
measure of the distance and speed of fall of rbcs in the plasma in a tube of standard bore and length
esr
most important factor influencing esr
action of plasma proteins
tube that can be used for both hct and esr
wintrobe tube
stages of esr
initial period of aggregation of rouleaux formation
10 min
stages of esr
period of fast settling
40 min
stages of esr
final period of packing
10 min
1st stage of esr
initial period of aggregation or rouleaux formation
2nd stage of esr
period of fast settling
3rd stage of esr
final period of packing
importance of esr [3]
index of presence of active infection
measures suspension stability
indicates abnormal concentration of fibrinogen, globulin and other plasma proteins
substitute for a pasteur pipette in filling the wintrobe tube
syringe with cannula
method of esr determination using the wintrobe tube
wintrobe-landsberg method
normal values for wintrobe-landsberg method
M 0-10 mm/hr
F 0-20 mm/hr
most sensitive method for esr determination
westergren method
used for serial study of chronic diseases like tb, carcinoma, and others
westergren method
fill westergren tube with blood using ?
rubber aspirator
normal values for westergren method
M 0-15mm/hr
F 0-17 mm/hr
Nonspecific method for assessing active diseases and inflammation
ESR
fast fall of rbcs may be due to
liver cirrhosis, cancer
effect of sickle cell on esr
high esr
effect of vibration on esr
high esr
effect of heat on esr
high esr
esr standing time
1 hr
