| 摘要 |
The present invention is an absorbent paper piece having a plurality of samples zones adapted to receive a liquid sample. The paper comprises an absorbent paper piece having a plurality of sample zones, each sample zone having a perforation extending substantially around its perimeter, so as to substantially obstruct the capillary flow of the liquid sample from one of the sample zones having an there sample zone adjacent thereto, to the other sample zone. It is preferred that the absorbent paper piece be provided with barrier perforations interposed between adjacent sample zones, so as to provide a gap between the sample zones as an additional capillary flow barrier. The absorbent paper piece may be adapted to hold any desired sample in liquid form such as laboratory reagents, and biological samples, such as blood samples (here used to include blood, products or components of blood, and blood hemolysate). The blood or blood products may also be arrayed in a series of sample zones for purposes of control and calibration, in accordance with practices known in the art. |
