The zeta sedimentation ratio (ZRS) was evaluated and found to have advantages over the erythrocyte sedimentation rate (ESR). The normal range for the ZSR proved to be 41 to 54%. Elevated ESR's obtained with the modified Westergren technic were also associated with an increased ZSR, except when amenia spuriously elevated the ESR. Reproducibility after storage was slightly better for the ZSR than for the ESR, But for optimal results the test should be performed within two hours of phlebotomy. Increased concentrations od EDTA anticoagulant may falsely elevate the ZSR, especially if the ZSR is initially elevated.
对zeta沉降率（ZRS）进行了评估，发现它比红细胞沉降率（ESR）具有优势。ZSR的正常范围为41%至54%。采用改良魏氏技术测得的ESR升高也与ZSR升高相关，但贫血假性升高ESR时除外。ZSR储存后的重现性略优于ESR，但为获得最佳结果，该检测应在静脉穿刺后两小时内进行。EDTA抗凝剂浓度增加可能会错误地升高ZSR，尤其是当ZSR最初就升高时。
