Method for evaluating reliability of immunochromatographic test, test strip, and kit

A method for evaluating a reliability of an immunochromatographic test for detecting a measurement target molecule in a specimen, the method comprising:

• (a) introducing a specimen into an introduction region;
• (b) diffusing the specimen from the introduction region toward a test region after the introduction;
• (c) detecting a molecule bound to a first capture molecule in the test region;
• (d) detecting a molecule bound to a second capture molecule in a check region;
• and
• (e) evaluating a reliability of an immunochromatographic test from detection results in (d) above,
• wherein the method uses a test strip,
• the test strip includes:
• the introduction region which is located on an upstream side of the test strip and into which the specimen is introduced,
• the test region which is located on a downstream side of the test strip and holds the first capture molecule that binds to the measurement target molecule or a capture molecule that binds to the first capture molecule, and
• the check region which is located between an upstream side end of the introduction region and a downstream side end of the test region and holds the second capture molecule that binds to a removal target molecule or a capture molecule that binds to the second capture molecule, and
• the removal target molecule is a molecule that binds to the first capture molecule and is different from the measurement target molecule.
