Researchers from the Third Military Medical University in China said they have developed a cheap, easy test to determine a patient's blood type in a matter of seconds with nearly perfect accuracy.

我国第三军医大学的研究人员日前表示，已研制出一种鉴定病人血型的低成本简易测试，准确率接近百分之百，耗时数秒。

The new assay is able to pinpoint whether a person is type A, B or O in just 30 seconds, and determine the blood type in full detail in about two minutes.

这项新测试能够在仅仅30秒内就准确鉴定某人的血型是A、B还是O，并在约两分钟内鉴定血型的所有详细情况。

Results on the new device were published in Science Translational Medicine.

《科学转化医学》杂志刊登了这一血型鉴定新方法的研究结果。

To create the test, the researchers took advantage of chemical reactions between blood serum proteins and a widely-available dye called bromocreosol green.

为了实现这项测试，研究人员利用了血浆蛋白和一种使用广泛的染料溴甲酚绿之间的化学反应。

Each test paper strip was also equipped with antibodies that recognized different blood type markers, such as A or B antigens, which can be found on the surface of red blood cells.

每张试纸也都配备有可以识别匹配不同血型的抗体，例如他们可以在血红细胞的表面发现A型或者B型血的抗原。
