IMMUNOASSAY APPARATUS

摘要

An immunoassay apparatus having a chromatographic strip having a substrate stuck to the lower surface thereof and a protective laminate stuck to the upper surface thereof, wherein a space is provided on the upper surface and/or the lower surface of at least a part of a color development area in the chromatographic strip. In this apparatus, capillary streams of a sample liquid in the chromatographic strip in its color development area are homogeneous, thus giving a high detection accuracy.
