Laboratory glass and plastics ware. Tubes for the measurement of the erythrocyte sedimentation rate by the Westergren method Ingestion-build-51215 the geometry of thread profile1 Scope This International Standard specifies requirements for single use and re usable glass and plastics tubes for measuring the erythrocyte sedimentation rate (ESR) by the Westergren method, and for a support to hold tubes during the performance of the test. These so called Westergren tubes are also sometimes designated as Westergren pipettes. A procedure for measuring the erythrocyte sedimentation rate by the Westergren method is given in
