To the Editor:
We evaluated the analytical performance of the Test-1 automated analyzer (Alifax S.p.A) for the assessment of the erythrocyte sedimentation rate (ESR). In this analyzer, 150-µL samples are aspirated, rotated slowly for 2 min, and put into the system, which measures the erythrocyte concentration in a capillary through a photometer at a wavelength of 950 nm. For each sample, a sedimentation curve is obtained, which is transformed to comparable Westergren values. The first result is obtained in <3 min, and subsequent results are obtained every 30 s (1)(2).
The Test-1 method was compared with both the manual Westergren
reference method and an automated Westergren method (Starrsed; Charles
Goffin Medical Systems) (3). Sodium citrate-anticoagulated
blood samples
