Laboratory glass and plastics ware. Tubes for the measurement of the erythrocyte sedimentation rate by the Westergren method Ingestion-build-512151 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
