Abstract
臨床檢測及定量異型血色素有兩大主要目的。第一為檢測醣化血紅素HbA1c (glycated hemoglobin A1),由血液中的葡萄糖長時間醣化HbA形成,應用於監控糖尿病患的血糖控制。第二為定量HbA1、HbA2、HbF及特殊血紅素比例,應用於診斷血液疾病如地中海型貧血及鐮刀型血球症等。為了迅速正確的檢測HbA1、HbA1c及HbA2、HbF及特殊血紅素比例。我們評估了Bio-Rad D-10 Dual program血色素測試系統,它使用了高效能液相層析法(HPLC)的原理,可以於6.5分鐘內完成分析。在HbA1c的部分,我們將現行使用的D-10 HbA1c program與D-10 Dual program進行比較。研究結果顯示23個 HbA1c自0.0 ﹪~ 13.9 ﹪的標本顯示兩種系統並無顯著差異存在,其相關係數為Y=0.9086X+0.014(X=HbA1c program,Y=Dual program,r2=0.9907 ,p=0.498)。在HbA2、HbF及特殊血紅素比例部分,我們將現行使用的Helena’s Hemoglobin Electrophoresis(Helena’s EP)與D-10 Dual program進行比較。研究結果顯示28個HbA2自0.9 ﹪~ 6.6 ﹪的標本,在分析HbA2比例上兩種系統並無顯著差異存在,相關係數為Y=0.6826X+0.8369(X=Helena’s EP,Y=Dual program,r2=0.5021 ,p=0.922)。在HbF部分則顯示D-10 Dual program對於低值HbF( HbF < 5.0 %, 15個HbF自0.0 ﹪~ 4.6 ﹪的標本實驗結果)具有較高的檢出值,平均Helena’s EP =0.17 %,Dual program=1.40 %(p=0.000906)。但在高值HbF( HbF > 5.0 %, 12個HbF自6.3 ﹪~ 64.3 ﹪的標本實驗結果) 在分析HbF比例上兩種系統並無顯著差異存在,相關係數為Y=0.7617X+9.007(X=Helena’s EP,Y=Dual program,r2=0.9158 ,p=0.852 )。實驗結果顯示Bio-Rad D-10 Dual program血色素測試系統提供了精確的方法定量HbA1c、HbA2及HbF,在線性及精確度上的表現良好,與現今使用的方法比較時也具有良好的相關性。而相對於血色素電泳,D-10 Dual program還可以提供HbF較高的檢出率。採用D-10 Dual program 將可提供下列優勢:長期監控糖尿病患及早期診斷妊娠糖尿病患精確的HbA1c檢驗結果、疑似地中海型貧血及缺鐵性貧血病患HbA2及HbF的快速診斷,以及將兩種檢驗合併於同一儀器檢驗可節省的檢驗時間、存放空間及費用。
