There is provided a method of measuring erythrocyte sedimentation rate (ESR) or plasma fibrinogen in a blood sample. The method involves treating the blood sample with a suitable anti-coagulant, placing the treated sample in a micro- haematocrit tube and centrifuging the sample at, for example, 500 rpm or greater whilst continually monitoring the sample using an IR light source and detector to follow appropriate separation band development during centrifugation. Thus, continual monitoring of the sample during the centrifugation process is possible. Desirably, the sample is horizontal throughout the centrifugation process.

La présente invention concerne une méthode de mesure de la vitesse de sédimentation des hématies (ESR) ou de fibrinogène plasmatique dans un échantillon de sang. Cette méthode comprend le traitement de l'échantillon de sang à l'aide d'un anticoagulant approprié, l'introduction de l'échantillon traité dans un tube à microhématocrite, la centrifugation de l'échantillon, par exemple, à 500 tpm ou à une vitesse plus élevée, tout en surveillant l'échantillon au moyen d'une source de lumière I.R. et d'un détecteur, de manière à suivre le développement précis des bandes de séparation. Ainsi, durant la centrifugation, il est possible de surveiller l'échantillon en continu. Il est souhaitable que l'échantillon soit en position horizontale durant toute la centrifugation.
