目的:对应用于全自动生化分析仪的同型半胱氨酸(Hcy )试剂进行分析性能验证,并应用于临床。方法在日本Olympus AU‐640全自动生化分析仪上对四川新成公司生产的循环酶法测定 Hcy试剂进行性能验证,参考CLSI EP6‐A、EP15‐A、EP‐7方案对检测方法的精密度、线性范围、干扰因素(胆红素、血红蛋白、乳糜)进行评估,与传统的高效液湘色谱法(HPLC)进行了比对,并对分析前质量控制影响因素进行实验分析。结果精密度实验为批内:CV 2.37%(低值)、3.58%(高值),总 CV :4.52%(低值)、4.85%(高值);该法与 HPLC法相关性良好(r2=0.996,P>0.05);线性范围为2.0~50.0μmol/L ,线性相关良好;试验浓度内的3种干扰物(胆红素小于或等于20 mg/dL ,三酰甘油小于或等于1000 mg/dL ,Hb≤150 mg/dL )对试剂无显著干扰;采血体位对结果有影响;全血标本1 h内分离血清,血清4℃12 h内及-20℃15 d内结果无明显变化;ED T A与肝素防凝血结果无差异。H cy水平与心脑血管病发生呈正相关,其阳性检出率高于传统的血脂指标。结论应用于全自动生化分析仪的循环酶法Hcy试剂具有较高的精密度和灵敏度,与HPLC测定相关良好,可满足临床测试要求,适合血清(浆)Hcy的常规和自动化分析。
目的:對應用于全自動生化分析儀的同型半胱氨痠(Hcy )試劑進行分析性能驗證,併應用于臨床。方法在日本Olympus AU‐640全自動生化分析儀上對四川新成公司生產的循環酶法測定 Hcy試劑進行性能驗證,參攷CLSI EP6‐A、EP15‐A、EP‐7方案對檢測方法的精密度、線性範圍、榦擾因素(膽紅素、血紅蛋白、乳糜)進行評估,與傳統的高效液湘色譜法(HPLC)進行瞭比對,併對分析前質量控製影響因素進行實驗分析。結果精密度實驗為批內:CV 2.37%(低值)、3.58%(高值),總 CV :4.52%(低值)、4.85%(高值);該法與 HPLC法相關性良好(r2=0.996,P>0.05);線性範圍為2.0~50.0μmol/L ,線性相關良好;試驗濃度內的3種榦擾物(膽紅素小于或等于20 mg/dL ,三酰甘油小于或等于1000 mg/dL ,Hb≤150 mg/dL )對試劑無顯著榦擾;採血體位對結果有影響;全血標本1 h內分離血清,血清4℃12 h內及-20℃15 d內結果無明顯變化;ED T A與肝素防凝血結果無差異。H cy水平與心腦血管病髮生呈正相關,其暘性檢齣率高于傳統的血脂指標。結論應用于全自動生化分析儀的循環酶法Hcy試劑具有較高的精密度和靈敏度,與HPLC測定相關良好,可滿足臨床測試要求,適閤血清(漿)Hcy的常規和自動化分析。

Objective To do performance verification for full automatic biochemical analyzer of homocysteine reagent analysis and applied in the clinic .Methods In Japan to push around AU‐640 fully automatic biochemical analyzer in sichuan new into the company′s production cycle enzymatic determination of homocysteine (Hcy ) reagent for performance verification ,reference CLSI EP6‐A ,EP15‐A ,EP‐7 scheme for the precision of the detection method ,linear range ,interference factors (bilirubin ,hemoglobin , chyle) assessed ,and the traditional ,the high efficiency liquid chromatography (HPLC) had carried on the comparison ,and the qual‐ity control before the influencing factors of experiment analysis .Results In precision experiments ,batch :CV2 .37 % (underval‐ued) ,3 .58% (high value) ,the total CV :4 .52% (low ) ,4 .85% (high value);In good correlation with HPLC method (r2 =0 .996 ,P>0 .996);The linear range of 2 .0-50 .0 μmol/L ,good linear correlation ;Test concentration within the three distractors (bilirubin 20 mg/dL or less ,triglycerides 1 000 mg/dL or less ,Hb 150 mg/dL or less) no significant interference of reagent ;In pursuance of postures have an impact on the results ;Whole blood specimens of 1 hour separation serum ,serum 4 ℃ for 15 days and 12 hours -20 ℃ results have no obvious change ;EDTA with heparin anti‐clotting results no difference .Hcy levels were positively correlated with cardio‐cerebrovascular disease ,the positive detection rate higher than that of the traditional blood fat index .Conclusion Through out the cycle of automatic biochemical analyzer enzymatic homocysteine reagent has high precision and sensitivity ,and tra‐ditional ,the high efficiency liquid chromatography (HPLC) determination of the related good ,can meet the requirements of clinical test ,is suitable for the normal serum (plasma Hcy) and automated analysis .
