Abstract
An immunochromatographic test strip that enables a specimen to sufficiently and quickly permeate into a sample application region within a test time, reducing variations in detection values of a test line. The test strip maintains consistent detection values even with whole blood specimens. The immunochromatographic test strip includes at least a sample application region, a development region, and a detection region, wherein the sample application region contains polyethylene glycol having a molecular weight of 15,000 to 700,000.
