The ESrT-system 200 comprises a 215 mm long vacuum aspiration venepuncture tube which contains anticoagulant diluent for the measurement of the erythrocyte sedimentation rate (ESR) without direct handling of the blood sample. This combines the advantage of a tube of "Westergren" length with a reduction in biohazard risk. Blood from 160 patients (ESR range 2-135 mm/first hour) was tested in parallel with the selected Westergren ESR method of the International Committee for Standardization in Haematology (ICSH) and a close correlation (r = 0.967) between the two methods was obtained. A second Westergren ESR, using anticoagulated but undiluted blood, was measured on 58 specimens to give an ICSH "expected" ESR. The ESrT-system 200 result was within 12 mm/first hour of the "expected" result for 91% of the specimens. This new ESR system is simple to use, does not require mathematical correction of the ESR reading for tube length, and gives results that are comparable with those obtained with the ICSH Westergren method.
ESrT - 200系统包含一根215毫米长的真空采血静脉穿刺管，管内装有抗凝稀释剂，用于测定红细胞沉降率（ESR），无需直接处理血样。这兼具了“魏氏”长度试管的优点，同时降低了生物危害风险。对160名患者（ESR范围为2 - 135毫米/第一小时）的血液与国际血液学标准化委员会（ICSH）选定的魏氏ESR方法进行了平行测试，两种方法之间获得了密切相关性（r = 0.967）。对58份标本进行了第二次魏氏ESR测定，使用抗凝但未稀释的血液以得出ICSH的“预期”ESR。对于91%的标本，ESrT - 200系统的结果在“预期”结果的每小时12毫米范围内。这种新的ESR系统使用简单，无需对ESR读数进行试管长度的数学校正，并且给出的结果与ICSH魏氏方法获得的结果相当。
