B C D

A E - increase ESR

Question 7

False about Wintrobe method of ESR
A.There should be no bubbles when filling the wintrobe tube
B.Placing in a SLANTING position decreases ESR
C.More popular method since Westergren needs greater blood volume and EDTA is a better anticoagulant

Answer 7

B

Increase dapat

Question 8

Which anticoagulant is used in Westergren method?
A.EDTA
B.sodium citrate
C.both

Answer 8

B

Question 9

Detection of ESR is screening test. T or F?

Answer 9

F

But it monitors disease activity.

Question 10

Which is not true about ESR sources of error?
A. Buffy coat should be included when WBC/platelets are high
B. Poor separation of plasma and RBC; maybe due to increased number of reticulocytes (stratified sedimentation)
C. Concentration of anticoagulant is greater than recommended

Answer 10

A

Excluded dapat

Question 11

Identify automated machine

will facilitate the work of the laboratory personnel, and the test results will be even more precise. Only requirement is to insert the ready-made pipettes into the analyzer; the subsequent process will take place automatically. The compatibility with the Westergren procedure is ensured:

Answer 11

SEDIKO M10

Question 12

• An automatic instrument controlled by a microprocessor and exclusively employed for analysis of the ESR.
• Also controls the temperature (18⁰C) • • Used in wards & small labs

Identify

Answer 12

DRAGONMED 2010

Question 13

Identify the machine

Incorporates many safety features such as:
o An overflow chamber
o A pierceable filling chamber cap designed to prevent spillage of blood during use and disposal

The filling reservoir is pre-filled with citrate or saline, has an enlarged mixing area, and several other “user friendly” (safety features) innovations

Answer 13

Dispette 2

Question 14

rate at which red blood cells sediment in a period of one hour; indirect measure of the presence of inflammation in the body

Identify

Answer 14

Erythrocyte sedimentation rate/Westergren sedimentation rate
