Siritantikom A A comparative study between the classical Westergren and the new sealed vacuum extrac-
tion methods for erythrocyte sedimentation rate determination was performed on 80 individual
subjects. The comparison-of-methods plot sealed vacuum extraction method (X)
vs
Westergren
method (Y) gave a least square linear regression equation of Y
=
1.001 X
+
0.03 (r
=
0.99) and
precision analysis gave a coefficient of variation below 3 per cent. Compared to the classical
method, the sealed vacuum extraction method was easy to use, showed acceptable precision and
reduced biohazard risk to the practitioner, therefore, it was suitable for a laboratory setting with a
high rate of blood-borne infectious diseases such as Thailand.
