A component of a sample may be detected or quantitatively measured by an immunoreaction, namely causing a target substance-immunoreactive reagent labelled with a marker-reaction product and/or any remaining, unreacted, immunoreactive reagent to move while making use of capillarity, causing the reaction product or any remaining, unreacted, immunoreactive reagent to combine with a substance packed in a capillary tube, and is immobilized on a carrier and adapted to uptake labelled substance so as to immobilize the reaction product or any remaining, unreacted, immunoreactive reagent, and measuring the amount of the thus-immobilized labelled substance. Since reagents are all filled in the capillary tube, there is no such troublesome that the reagents have to be prepared and/or any extra reagents have to be discarded upon conducting the measurement. The immunoassay may be carried out at bed side in hospitals. An extremely small amount of the sample may be sufficient for its measurement. After the measure- 'ment, the capillary tube may be stored as is or may be thrown away with ease.
可以通过免疫反应来检测或定量测量样品中的某种成分,即利用毛细管的流动性,使标记有标记物-反应产物的目标物质-免疫反应试剂和/或任何剩余的、未反应的免疫反应试剂移动,使反应产物或任何剩余的、未反应的免疫反应试剂与装在毛细管中的物质结合,并固定在载体上,以吸收标记物,从而固定反应产物或任何剩余的、未反应的免疫反应试剂、使反应产物或剩余的未反应的免疫反应试剂与毛细管中的物质结合,并固定在载体上,使其吸收标记物质,从而固定反应产物或剩余的未反应的免疫反应试剂,并测量由此固定的标记物质的量。由于试剂都装在毛细管中,因此不存在必须准备试剂和/或进行测量时必须丢弃多余试剂的麻烦。免疫测定可在医院床边进行。只需极少量的样本即可进行测量。测量结束后,毛细管可原样保存或轻松丢弃。
