Modification of a commercial haemagglutination assay for the detection of anti-HBs has reduced the test time from over one hour to approximately 25 min. increased sensitivity ten-fold without any prozoning, maintained specificity and reduced costs by 90%. The modification consists of diluting the reagent cells ten-fold; these are then added to dilutions of test serum in a V-well microplate. After incubation, plates are centrifuged and then inclined at 70 degrees. Positive and negative reactions can be clearly distinguished within approximately 10 minutes.
对用于检测抗-HBs的商业血凝试验进行的改进,已将检测时间从一个多小时缩短至约25分钟。灵敏度提高了十倍,不存在前带现象,保持了特异性,并将成本降低了90%。改进方法包括将试剂细胞稀释十倍;然后将其加入V型孔微量滴定板中的待测血清稀释液中。孵育后,对滴定板进行离心,然后倾斜70度。大约10分钟内即可清晰区分阳性和阴性反应。
