Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical technology, in particular to a TMV rapid testing card. Background Art
[0002] The Tobacco Mosaic Virus (TMV) rapid test card is a test paper or card used to quickly detect tobacco mosaic virus. This rapid test card uses immunochromatography technology and the binding reaction of specific antibodies and viruses to quickly detect whether tobacco mosaic virus exists in the sample. When using the tobacco mosaic virus rapid test card, the collected sample (such as leaves, tobacco, etc.) needs to be dripped into the sample addition hole of the rapid test card, and then the result is judged by observing the color changes of the test line and the control line. If the test line changes color, it means that the sample contains tobacco mosaic virus; if the control line changes color, it means that the rapid test card is working normally and the detection is effective.
[0003] However, when using some existing rapid test cards, users manually add samples, which makes it difficult to control the amount. If the amount added is too much, it may cause excessive reaction on the test paper or reagent card, resulting in a false positive result. If the amount added is too little, it may cause inaccurate test results or false negative results. For this reason, we propose a pen-type TMV rapid test card. Utility Model Content
