The utility model discloses an agglutinating test tube which can be used for instrument colorimetry. Its shape is square column shape, its wall transmits light, and the test tube has two cavities, one is spherical cavity, the other is square column cavity, the spherical cavity is located at the bottom of the test tube, the square column cavity is located at the middle to the top of the test tube, and the spherical cavity is located at the middle to the top of the test tube. The upper part of the cavity has a circular opening, and the lower part of the square cylindrical cavity has a funnel shape. The funnel mouth is connected with the circular opening, and the two cavities are connected. The spherical cavity can accommodate the sediment in the test tube and prevent the liquid disturbance caused by moving the test tube from flooding the sediment; the square-cylindrical cavity part is like a colorimetric dish, so the test tube can be used in spectrophotometer, and the agglutination test can interpret the experimental results by spectrophotometry, which is more objective and accurate. The data base can be preserved for a long time, and the disagreement caused by naked eye interpretation can be overcome.

可用于仪器比色的凝集试管
本技术涉及一种生化实验室用的玻璃器皿,具体涉及的是一种布病试管凝集试验中使用的凝集试管。
技术介绍
布病试管凝集试验(SAT)是一种稳定性、特异性、敏感性较高的检测方法,一直是各国用作诊断人和动物布鲁氏菌病的常规血清学诊断方法,我国将其列为动物布鲁氏菌病诊断的国标法定正式试验。依据GB/T18646-2002,在动物布鲁氏菌病(以下简称布病)的诊断技术中,“虎红平板凝集试验(RBPT),乳牛全乳环状试验(MRT)适用于家畜布病田间筛选试验和乳牛场布病的监测及诊断泌乳母牛布病的初筛试验;试管凝集试验(SAT)和补体结合试验(CFT)适用于诊断羊种、牛种和猪种布病感染的家畜”。然而,一直以来布病试管凝集试验方法中,试验结果的判读均为人工肉眼判读,即肉眼观察试管中受检血清的凝集现象,以此判定血清中抗体的相对含量。这种依靠人工肉眼判读必然存在误差,特别是在凝集现象不太明显时,试验员的工作经验、眼睛辨色力以及视力的差异会判读出不同的结果。因此,人们尝试用仪器来判读,最好的一种选择是用分光光度计对凝集试管中的液体做透光率的测定,通过透光率得到判读的数 ...
