Wes·ter·gren meth·od

(vest'ĕr-gren),
a procedure for estimating the sedimentation rate of red blood cells in fluid blood by mixing venous blood with an aqueous solution of sodium citrate and allowing it to stand in an upright standard pipette (200 mm long) filled to the zero mark; the fall of the red blood cells, in millimeters, is then observed in 1 hour; the normal rate for men is 0-15 mm (average, 4 mm), and for women 0-20 mm (average, 5 mm).

Westergren method

A method for determining ESR. See Zetacrit.

Some methods require that the results be read in as little as 15 minutes, as opposed to one hour for the Westergren method. The Diesse Mini-Ves is a four-place point-of-care instrument that reads the ESR at 20 minutes and is the second most popular method according to the College of American Pathologists survey.
Barrett and Hill conducted a study comparing the Micro-Dispette method (Guest Medical) to the Westergren method. While the Micro-Dispette method showed higher values using venous blood than those obtained by the reference method, there was good correlation between the micro-dispette method using capillary blood and the reference method using venous blood.
In conclusion, the Test-1 offers a fast determination of the ESR with acceptable intraassay variability and good correlation with traditional Westergren methods. The bias and agreement limits are comparable to those found by others (6, 7).
AIMS AND OBJECTIVES: The study was conducted with the primary objective of comparing the VesMATIC cube80[TM] analyzer with the modified Westergren method for the analysis of ESR.
CONVENTIONAL WESTERGREN METHOD: In this method, a disposable, plastic tube with a
ESR was measured using Westergren method, while anti-CCP was estimated by enzyme-linked immune sorbent assay (ELISA).
Results are measured in millimeters per hour (modified Westergren method) and are available in 30 minutes (a calculated prediction is available in 15 minutes).
ESR was measured by a modified Westergren method. Statistical analyses were performed with the Statistical Analysis System (SAS Institute).
Laboratory investigation included erythrocyte sedimentation rate (ESR) (using the standard Westergren method), serum C-reactive protein (CRP) (using the nephelometer assay), total blood count and rheumatoid factor measurements.
(3) One of the popular ESR methods is the Westergren method, which has been reported to be marginally affected by age, race and blood storage.
