Definition of clinical significant 
 An antibody is considered clinically significant if it is capable of inducing either hemolytic disease of the 
fetus/newborn (HDFN) or accelerated red cell destruction. 
 A term used to describe the likelihood a particular blood group antibody that can cause one of two 
problems: 1) Hemolytic transfusion reactions (accelerated red blood cell destruction), or 2) Hemolytic 
disease of the fetus/newborn (HDFN). 
 In general, red cell antibodies that react at body temperature (37 C) are more likely to be significant 
 Most warm antibodies are IgG class rather than IgM. 
 Antibodies that can cross the placenta and circulate in the fetus are obviously more likely to cause 
HDFN, so IgG antibodies are more likely than IgM to be significant from that perspective. However, this 
does NOT mean that all IgM antibodies are insignificant. 
 One of the clues as to whether or not an antibody will be "significant" is whether or not the antibody 
reacts at body temperature (37C). The optimal reaction temperature of an antibody is not always 
predictive of its clinical significance, but it can definitely guide you in the right direction

Definition of Manual Polybrene (MP) only allo-antibodies 
 Manual polybrene (MP) : Modified manual Polybrene method : Marie Lin林媽利醫師所引進及改進 
適用於台灣地區的方法,和文獻上使用的Manual Polybrene test ( MPT) 或Low ionic Polybrene 
( LIP )略有不同。 
 台灣地區常最使用的主要抗體篩檢方法為manual Polybrene法,臨床上常見紅血球異體抗體在傳統 
classical AHG法無法偵測,但使用Manual polybrene法卻可以偵測到,此類紅血球抗體定義為MP 
only allo-antibodies。 
 Manual polybrene法反應溫度在室溫,又台灣使用的modified manual Polybrene並沒有使用anti-human 
IgG antibody,通常對冷型抗體反應較傳統classic AHG 反應較敏感(sensitivity較高).

Background 
 導入血庫自動化檢驗儀器前,曾評估MP法和CAT法的差異性結果如下: 
使用傳統MP法執行抗體篩檢之異體不規則抗體檢出率約為0.86%(506 / 59095)(抗體/總檢體數),其 
中抗體鑑定結果為MP only 約占18%(94/506);而CAT法之異體不規則抗體檢出率約為1%(520 / 
51727),抗體鑑定結果為MP only約為3.5%(18/520)。分析抗體特異性,MP法異體抗體之較高比例 
為anti-Mia(42%), anti-E(&c)(31%), anti-Lea(6%) , 而CAT 法之較高抗體分析為anti-Mia(43%), anti- 
E(&c)(25%) , anti-M(8%) 
 使用血庫自動化檢驗儀器後,經常發現使用CAT法抗體篩檢陰性,但使用MP交叉試驗法卻為交叉不 
合,抗體鑑定結果為anti-e, anti-Jka, anti-E, anti-Mia等。且多例為輸血後檢體才檢驗出,疑為輸血產 
生異體抗體。 
 常見的MP only allo-antibodies經常為冷反應型(cold reactive allo-antibodies), 如anti-Mia, anti-E, 
antiP1, anti-M, anti-Lea, anti-Leb, anti-I等,但也偶見如anti-Jka, anti-Jkb, anti-e, anti-c等抗體。本研 
究希利用血清學方法分析探討MP only allo-antibodies的血清特性。

Conclusions 
Reference 
Column Agglutination Technology (CAT)是1990年初發展出的新技術用 
以檢測抗原抗體間的反應,本院於2001年開始將CAT法應用在抗體 
鑑定,直至2012年9月中才全面以自動化血型分析儀應用於抗體篩 
檢,取代Manual Polybrene (MP)法。根據CAP 2013 Transfusion 
medicine JB survey ,結果分析顯示Gel testing佔所有Antibody 
screening 方法約66%(2290/3492) , Tube method 約31%(1075/3492); 
因此以CAT執行抗體篩檢已漸漸成為國際趨勢。 
使用傳統MP法執行抗體篩檢之異體不規則抗體檢出率約為0.86% 
(506 / 59095)(抗體/總檢體數),其中抗體鑑定結果為MP only 約 
占18%(94/506);而CAT法之異體不規則抗體檢出率約為1%(520 / 
51727),抗體鑑定結果為MP only約為3.5%(18/520)。分析抗體特 
異性,MP法異體抗體之較高比例為anti-Mia(42%), anti-E(&c)(31 
%), anti-Lea(6%) , 而CAT 法之較高抗體分析為anti-Mia(43 
%), anti-E(&c)(25%) , anti-M(8%)。

2.抗體特異性:新檢出抗體以CAT為主要抗體鑑定法,其他則為MP、

MP Method CAT 
Anti-M 
分析結果顯示:CAT法之異體不規則抗體檢出率較MP法高;Rh類 
抗體有較明顯比例差異,探討原因可能為MP法對Rh類抗體較 
sensitive,所以檢出較高MP only之Rh類抗體約20%( 41/198)。但就 
anti-M及anti-Lea之檢出結果則為CAT法檢出較多,其原因可能為 
部份較弱之anti-M及anti-Lea抗體反應特性在MP法判讀時較容易散 
開,不易被檢出。其他具臨床意義之抗體如anti-Jka, -Jkb, -S及-Fyb 
則在CAT法(6.3%)較MP法(4.7%)有較佳之檢測結果。 
結論:抗體檢出率CAT法檢出率為(1%)較傳統MP法(0.86%)好,而 
就檢出抗體分析,以CAT法screening出較多AHG反應之抗體如anti- 
Jka, -Jkb, -S及-Fyb。自動化血型分析儀之CAT法作業模式可以將實 
驗室間人員操作及判讀上差異降低,提高抗體之檢出。此外Anti- 
Mia, anti- E(含c)為本院最常見之異體不規則抗體,此與國內之其他 
發表文獻結果ㄧ致。 
Objectives 
MP是臺灣最常用的抗體篩檢法,其特點是反應時間短,對冷型抗 
體及Rh類抗體之敏感度高,但對於一些反應溫態為AHG的抗體如 
anti-Kidd, anti-Duffy & anti-Kell則較不敏感; CAT法則對AHG抗體有 
較高的敏感性,以自動化血型分析儀可將操作及判讀更標準化,可 
減少人為操作及判讀上的誤差。本研究目的為比對CAT與MP此兩種 
不同抗體篩檢方法,並分析其免液凝集敏感度對抗體篩檢檢出率及 
檢出抗體特異性。

結論 
此次評估結果發現,AutoVue CAT和傳統試管法進行血型比對結果幾乎達到一致性;但在不規則抗體篩檢之比對差異較大,主要是因MP 
法會篩出的不具臨床意義之IgM冷型抗體!輸血前檢驗自動化除了可標準化減少人為操作及判讀上之誤差,最重要是可以減少文書抄寫錯誤, 
所以已漸漸成為國際驅勢!

Literature review-1 
 Manual hexadimethrine bromide (Polybrene) tests (Polybrene in low-ionic medium) were used in 
parallel with manual low-ionic-strength solution (LISS) procedures for the routine testing of patient 
samples referred to a general hospital blood bank. Of 5646 consecutive sera tested, 5167 (91.5%) 
did not react with either technique; 320 sera (5.7%) reacted in both methods. The Polybrene 
technique detected 63 antibodies which did not react in the LISS methods. One hundred sera did 
not react in the Polybrene test, but did react in the LISS methods. Sera showing discrepant results 
between the 2 methods were further tested in a reference laboratory. Polybrene tests appeared to 
be better in avoiding reactions due to clinically nonsignificant antibodies. The LISS methods 
appeared to be more sensitive in detecting antibodies of potential clinical significance.

Literature review-2 
 To explore the comparison of values of microcolunm gel test and polybrene test in irregular 
antibody detection.Methods From 2010 to 2011, 
6 720 cases with blood transfusion were test by microcolumn gel and polybrene for detecting 
irregular antibody,and then positive results were tested about antibody′s specificity by anti-human 
globulin test. 
28 irregular antibody positive cases were detected by microcolumn gel test and positive rate was 
0.42%.Only 26 cases were detected by polybrene test, and positive rate was 0.39%,there was no 
statistically significant difference between two methods

Purpose 
 台灣地區常最使用的主要抗體篩檢方法為manual Polybrene法,臨床上常見紅血球異體抗體在傳統 
classical AHG法無法偵測,但使用Manual polybrene法卻可以偵測到,此類紅血球抗體定義為MP 
only allo-antibodies。 
 常見的MP only allo-antibodies經常為冷反應型(cold reactive allo-antibodies), 如anti-Mia, anti-E, anti- 
P1, anti-M, anti-Lea, anti-Leb, anti-I等,但也偶見如anti-Jka, anti-Jkb, anti-e, anti-c等抗體。本研究希 
利用血清學方法探討MP only allo-antibodies的血清特性。 
 自從採用血庫自動化設備,偶見MP only allo-antibodies影響血庫作業程序,此探討對MP only allo-antibodies 
的血清特性了解,可以增進對此類抗體的特性了解,改善輸血作業流程,並增加輸血安全。

Case report 
 某月2013 : 男46Yrs HCC 因anemia Hb 6.5g/dL輸血每週2U  3,第三次輸血前AutoVue Innova 
BioVue antibody screening negative, 但交叉試驗使用manual Polybrene法呈現incompatible. 經抗體 
鑑定為MP only anti-Jka . 
 March 某年: 女52 yrs Myoma Hb 7.2g/dL 輸血,分別於2/28, 3/26, 4/2欲輸血packed RBC各2U, 期 
間似乎輸注效果不甚理想,4/2的MP 交叉試驗呈現incompatible,經抗體鑑定為MP only anti-E.

案例分享 
 一泌尿科F82歲婦女血色素6.8備輸血LDPR 3u, 使用CAT法antibody screening negative, QD輸血1U 
三天, 第一天輸血使用is交叉, 第二天則使用mp交叉, 但都相合血, 第三天mp交叉不合, 經抗體鑑定無 
抗體, 重新發出血液 
 經重新MP antibody screening 為2+,0,0 
 MP抗體鑑定為MP only anti-E
案例討論 
 假如輸了MP-only抗體交叉不合的血, 輸血反應及輸注療效評估。 
 MP only 抗體的來源可能性 
- IgM抗體 
- 之前輸血或懷孕產生,經長期未刺激維持低titer的存在 
- 最近輸血產生,active IgM先產生或產生titer尚無法使用CAT或AHG偵測到,但MP法可以偵試到‧
Anti-Mia MP only trans-placenta 
 A case report of a anti-Mia (MP only ) 
 Because of few fetus plasma , MP antibody screening positive, but CAT antibody screening 
negative 
 recheck mother antibody screening : CAT antibody screening negative, MP only anti-Mia antibody 
present.

Continue study 
 MP antibody screening positive, CAT antibody identification negative, MP-only antibody. 
 CAT antibody screening negative,從MP cross match , 可以找到交叉不相容的血液,進而鑑定出 
MP-only allo-antibody. 
 從CAT antibody screening positive , period transfusion , antibody decreasing 是否可以找到MP-only 
antibody?

  • 1. Are manual Polybrene ( MP) only antibodies clinical significance ? Serological View. 張志昇 馬偕紀念醫院 2014/11/5
  • 2. Outline  Definition of clinical significant antibody & MP only allo-antibody  Background  Literature review  Purpose  Case reports  Laboratory finding  Conclusion 小張的報告 Page 2
  • 3. Definition of clinical significant  An antibody is considered clinically significant if it is capable of inducing either hemolytic disease of the fetus/newborn (HDFN) or accelerated red cell destruction.  A term used to describe the likelihood a particular blood group antibody that can cause one of two problems: 1) Hemolytic transfusion reactions (accelerated red blood cell destruction), or 2) Hemolytic disease of the fetus/newborn (HDFN).  In general, red cell antibodies that react at body temperature (37 C) are more likely to be significant  Most warm antibodies are IgG class rather than IgM.  Antibodies that can cross the placenta and circulate in the fetus are obviously more likely to cause HDFN, so IgG antibodies are more likely than IgM to be significant from that perspective. However, this does NOT mean that all IgM antibodies are insignificant.  One of the clues as to whether or not an antibody will be "significant" is whether or not the antibody reacts at body temperature (37C). The optimal reaction temperature of an antibody is not always predictive of its clinical significance, but it can definitely guide you in the right direction 小張的報告 Page 3
  • 4. Definition of Manual Polybrene (MP) only allo-antibodies  Manual polybrene (MP) : Modified manual Polybrene method : Marie Lin林媽利醫師所引進及改進 適用於台灣地區的方法,和文獻上使用的Manual Polybrene test ( MPT) 或Low ionic Polybrene ( LIP )略有不同。  台灣地區常最使用的主要抗體篩檢方法為manual Polybrene法,臨床上常見紅血球異體抗體在傳統 classical AHG法無法偵測,但使用Manual polybrene法卻可以偵測到,此類紅血球抗體定義為MP only allo-antibodies。  Manual polybrene法反應溫度在室溫,又台灣使用的modified manual Polybrene並沒有使用anti-human IgG antibody,通常對冷型抗體反應較傳統classic AHG 反應較敏感(sensitivity較高). 小張的報告 Page 4

  • 6. Background  導入血庫自動化檢驗儀器前,曾評估MP法和CAT法的差異性結果如下: 使用傳統MP法執行抗體篩檢之異體不規則抗體檢出率約為0.86%(506 / 59095)(抗體/總檢體數),其 中抗體鑑定結果為MP only 約占18%(94/506);而CAT法之異體不規則抗體檢出率約為1%(520 / 51727),抗體鑑定結果為MP only約為3.5%(18/520)。分析抗體特異性,MP法異體抗體之較高比例 為anti-Mia(42%), anti-E(&c)(31%), anti-Lea(6%) , 而CAT 法之較高抗體分析為anti-Mia(43%), anti- E(&c)(25%) , anti-M(8%)  使用血庫自動化檢驗儀器後,經常發現使用CAT法抗體篩檢陰性,但使用MP交叉試驗法卻為交叉不 合,抗體鑑定結果為anti-e, anti-Jka, anti-E, anti-Mia等。且多例為輸血後檢體才檢驗出,疑為輸血產 生異體抗體。  常見的MP only allo-antibodies經常為冷反應型(cold reactive allo-antibodies), 如anti-Mia, anti-E, antiP1, anti-M, anti-Lea, anti-Leb, anti-I等,但也偶見如anti-Jka, anti-Jkb, anti-e, anti-c等抗體。本研 究希利用血清學方法分析探討MP only allo-antibodies的血清特性。 小張的報告 Page 6
  • 7. 臨床抗體篩檢CAT法與MP法檢出率及檢出抗體 特異性之比對分析 簡妙如林美華林霈文廖文綱詹如萍王綉棉劉斐雲羅仕錡 國立台灣大學附設醫院檢驗醫學部 Background Results Table 1.MP & CAT檢出抗體陽性結果比較表 Table 2.MP & CAT檢出抗體特異性結果分析表 Anti-Lea Conclusions Reference Column Agglutination Technology (CAT)是1990年初發展出的新技術用 以檢測抗原抗體間的反應,本院於2001年開始將CAT法應用在抗體 鑑定,直至2012年9月中才全面以自動化血型分析儀應用於抗體篩 檢,取代Manual Polybrene (MP)法。根據CAP 2013 Transfusion medicine JB survey ,結果分析顯示Gel testing佔所有Antibody screening 方法約66%(2290/3492) , Tube method 約31%(1075/3492); 因此以CAT執行抗體篩檢已漸漸成為國際趨勢。 使用傳統MP法執行抗體篩檢之異體不規則抗體檢出率約為0.86% (506 / 59095)(抗體/總檢體數),其中抗體鑑定結果為MP only 約 占18%(94/506);而CAT法之異體不規則抗體檢出率約為1%(520 / 51727),抗體鑑定結果為MP only約為3.5%(18/520)。分析抗體特 異性,MP法異體抗體之較高比例為anti-Mia(42%), anti-E(&c)(31 %), anti-Lea(6%) , 而CAT 法之較高抗體分析為anti-Mia(43 %), anti-E(&c)(25%) , anti-M(8%)。 1.檢出率:檢體樣本數以回溯方式分析比較自2011年10月至2012年 9月所有輸血及備血檢 體以MP法執行抗體篩檢 及2012年10月至2013年 8月中以CAT法執行抗體 篩檢之總檢體量(為分 母),及新檢出之異體抗 體數(為分子),分析比 較抗體檢出率。 2.抗體特異性:新檢出抗體以CAT為主要抗體鑑定法,其他則為MP、 3 phases AHG method; 本次分析抗體以新檢出 異體抗體為主,已鑑定 過之抗體及自體抗體則 不重覆計算,多重抗體 則可重覆計數。 AHG抗體 MP Method CAT Anti-M 分析結果顯示:CAT法之異體不規則抗體檢出率較MP法高;Rh類 抗體有較明顯比例差異,探討原因可能為MP法對Rh類抗體較 sensitive,所以檢出較高MP only之Rh類抗體約20%( 41/198)。但就 anti-M及anti-Lea之檢出結果則為CAT法檢出較多,其原因可能為 部份較弱之anti-M及anti-Lea抗體反應特性在MP法判讀時較容易散 開,不易被檢出。其他具臨床意義之抗體如anti-Jka, -Jkb, -S及-Fyb 則在CAT法(6.3%)較MP法(4.7%)有較佳之檢測結果。 結論:抗體檢出率CAT法檢出率為(1%)較傳統MP法(0.86%)好,而 就檢出抗體分析,以CAT法screening出較多AHG反應之抗體如anti- Jka, -Jkb, -S及-Fyb。自動化血型分析儀之CAT法作業模式可以將實 驗室間人員操作及判讀上差異降低,提高抗體之檢出。此外Anti- Mia, anti- E(含c)為本院最常見之異體不規則抗體,此與國內之其他 發表文獻結果ㄧ致。 Objectives MP是臺灣最常用的抗體篩檢法,其特點是反應時間短,對冷型抗 體及Rh類抗體之敏感度高,但對於一些反應溫態為AHG的抗體如 anti-Kidd, anti-Duffy & anti-Kell則較不敏感; CAT法則對AHG抗體有 較高的敏感性,以自動化血型分析儀可將操作及判讀更標準化,可 減少人為操作及判讀上的誤差。本研究目的為比對CAT與MP此兩種 不同抗體篩檢方法,並分析其免液凝集敏感度對抗體篩檢檢出率及 檢出抗體特異性。 Figure 1.MP抗體陽性處理流程 Abbrev.

  • 13. Literature review-1  Manual hexadimethrine bromide (Polybrene) tests (Polybrene in low-ionic medium) were used in parallel with manual low-ionic-strength solution (LISS) procedures for the routine testing of patient samples referred to a general hospital blood bank. Of 5646 consecutive sera tested, 5167 (91.5%) did not react with either technique; 320 sera (5.7%) reacted in both methods. The Polybrene technique detected 63 antibodies which did not react in the LISS methods. One hundred sera did not react in the Polybrene test, but did react in the LISS methods. Sera showing discrepant results between the 2 methods were further tested in a reference laboratory. Polybrene tests appeared to be better in avoiding reactions due to clinically nonsignificant antibodies. The LISS methods appeared to be more sensitive in detecting antibodies of potential clinical significance. Transfusion. 1985 Mar-Apr;25(2):145-8. 小張的報告 Page 13

  • 24. Purpose  台灣地區常最使用的主要抗體篩檢方法為manual Polybrene法,臨床上常見紅血球異體抗體在傳統 classical AHG法無法偵測,但使用Manual polybrene法卻可以偵測到,此類紅血球抗體定義為MP only allo-antibodies。  常見的MP only allo-antibodies經常為冷反應型(cold reactive allo-antibodies), 如anti-Mia, anti-E, anti- P1, anti-M, anti-Lea, anti-Leb, anti-I等,但也偶見如anti-Jka, anti-Jkb, anti-e, anti-c等抗體。本研究希 利用血清學方法探討MP only allo-antibodies的血清特性。  自從採用血庫自動化設備,偶見MP only allo-antibodies影響血庫作業程序,此探討對MP only allo-antibodies 的血清特性了解,可以增進對此類抗體的特性了解,改善輸血作業流程,並增加輸血安全。 小張的報告 Page 24
