Description of the invention: • [Technical field to which the invention pertains] The present invention relates to a test strip, and more particularly to a test strip for rapid detection of snake venom which can quickly and effectively detect the presence or absence of snake venom in human serum. [Prior Art] Snake bite is one of the common medical problems in tropical and subtropical regions. Taiwan is located in the subtropical zone, with warm and humid climate, many alpine hills and dense forests. The terrain and climate characteristics make it such a small island in Taiwan. More than forty species of terrestrial snakes, including six highly virulent snakes, pose a life-threatening threat to the inhabitants: cobra (Α/α/α, umbrella festival (Swwgijrws multicinctus), oxygen mask H (Protobothrops mucrosquamatus) ) 'Red tail, rounded {Trimeresurus stejnegeri), hundred steps snake {Deinagkistrodon acutus) ' ^ ^^{Daboia rwMe/z·/ . Although these six species of snakes belong to different families and genera, the clinical signs after being bitten overlap. If the patient is bitten by a snake suddenly or in the darkness of the day, often © will not be able to identify the correct snake species because they do not clearly see or can not catch the biting snake, if only based on clinical characterization, such as: In addition to bite marks, local wounds, and subjective descriptions of patients to identify snake species, it is easy to cause misjudgment, and miss the golden opportunity of treatment. In order to make a correct diagnosis, it is usually dependent on the laboratory test results. Although the currently developed sandwich ELISA method can more accurately detect and confirm the cobra, turtle flower, red-tailed hawksbill or chain snake venom in the patient's specimen, in fact, the following methods still exist in this test method: 201013186 Application The sandwich ELISA method takes about 5 hours to verify the bite of the snake species' and evaluates the clinical severity, prognosis and serum treatment of the snake bite. In addition, the experimental procedures for performing ELISA are cumbersome, and the instruments for testing are not easily popularized in various laboratories. Therefore, it is necessary to train professional technicians who can operate the instruments, so that the existing snake venom test method has complicated inspection procedures and time consuming. The disadvantages of using a specific instrument and being operated by trained personnel, coupled with the inability to quickly learn the results, make it impossible for clinical staff to make a correct diagnosis immediately and to delay the timing of treatment and the risk of misdiagnosis. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a snake venom which is highly specific and saves inspection time by using immunoassay inspection technology and chromatographic principle to quickly and efficiently confirm snake venom in serum samples. Quickly test the test piece. Thus, the snake venom rapid test strip of the present invention is for detecting a specific snake venom in a biological specimen, comprising a test card body, and an implant unit disposed on the test card body. The test card body includes a base layer and a carrier layer which are correspondingly joined, and the carrier layer has a sample spacer spaced apart from each other, an absorbing pad, and a gold mark adjacent to the sample pad. a spacer, and a porous film connected between the gold bond pad and the absorbing pad, and forming a test line area and a control line area spaced apart from each other on the porous film. The implant unit comprises a plurality of anti-venom gold-labeled antibodies distributed in the gold-labeled gasket of the test card, and a plurality of control lines of the multi-201013186 thin crucible fixed on the test card body. A first antibody that binds to the gold-labeled antibody, and a plurality of second antibodies that are immobilized in the test line region of the porous membrane for binding to a gold-labeled antibody that binds to snake venom. The beneficial effects of the present invention are: when the biological sample is dropped onto the carrier layer of the test card body, the sample is moved to the pad gold gasket by capillary action, and The anti-venom gold-labeled antibody in the pad gold gasket interacts and continues to move along the porous film to the test line region and the control line region to interact with the second and first antibodies, respectively. Determining whether the test strip is valid by interpreting whether the control line area is colored, and determining whether the sample contains snake venom by interpreting whether the test line area is colored or not, thereby enabling the present invention to quickly and effectively check out Whether the biopsy contains specific snake venom for immediate treatment.
