Abstract
The present invention relates to an immunochromatographic test strip (1) which can be encoded such that the test result cannot be understood by the user who performs the test. The test strip (1) subject of invention, includes at least one sample pad (2) in which the samples are loaded, at least one conjugate pad (3) having analyte-specific labeled antibodies present in the sample, at least one membrane (4) wherein the antibodies bound or unbound to the analyte moves forward and at least one absorption pad (5) providing movement of the sample and a two-dimensional barcode (6) on the membrane (4) that provides the authorities to interpret the results and avoids one who takes test image after test so that the test taker does not immediately understand the test result.
Claims11
An immunochromatographic test strip to prevent an interpretation of test results by a user performing the immunochromatographic test, comprising:
- at least one sample pad in which a sample is loaded;
- at least one conjugate pad having analyte-specific labeled antibodies, that bind specifically to analytes present in the sample, and at least one membrane onto which the labeled antibodies, whether bound or unbound to the analyte, migrate from the conjugate pad;
- at least one absorption pad providing advancement of the sample;
- and
- a two-dimensional barcode located on the membrane, the barcode comprising:
- at least one content fixed zone comprising barcode content that does not vary according to a test result, and
- one or more content-varying regions comprising barcode content that varies according to the test result, wherein the content-varying regions are located on the barcode in such a way that they do not come in succession, at least one part of the content-varying regions comprises analyte specific antibodies, and all antibodies-specific secondary antibodies, and at least one of the content varying regions is empty.
