[0035] like Figure 8 As shown, further, the test paper 8 includes: a gold label pad 81, a sample pad 82, a blood filter membrane 83, a nitrocellulose membrane 84, an absorbent paper 85 and a rubber plate; the rubber plate 86 is arranged on the bottom surface of the inner cavity of the test box 1; the sample pad 82 is arranged at one end of the upper surface of the rubber plate 86 and is located below the sample addition hole 3, one end of the blood filter membrane 83 is arranged at one end of the lower surface of the sample pad 82, and the lower surface of the blood filter membrane 83 is in contact with the rubber plate 86, one end of the gold label pad 81 is arranged at the bottom of the other end of the blood filter membrane 83, and the lower surface of the gold label pad 81 is in contact with the rubber plate 86, one end of the nitrocellulose membrane 84 is arranged at the bottom of the other end of the gold label pad 81, and the lower surface of the nitrocellulose membrane 84 is in contact with the rubber plate 86, and the absorbent paper 85 is arranged on the upper surface of the other end of the nitrocellulose membrane 84, and the lower surface of the absorbent paper 85 is in contact with the rubber plate 86.

[0036] The test strip 8 uses colloidal gold immunochromatography technology and the capture method principle. An IgG detection line, an IgM detection line and a quality control line C are sequentially arranged on the nitrocellulose membrane 84; the IgG detection line is coated with mouse anti-human IgG monoclonal antibody, the IgM detection line is coated with mouse anti-human IgM monoclonal antibody, the quality control line C is coated with biotin, and the gold label pad 81 is coated with colloidal gold-labeled recombinant Helicobacter pylori antigen and streptavidin. When a positive sample is detected, the Helicobacter pylori IgG and (or) IgM antibodies in the sample combine with the colloidal gold-labeled recombinant Helicobacter pylori antigen to form (Au-HP-Ag)-(HP-IgG) or (Au-HP-Ag)-(HP -IgM) immune complex, due to the chromatography, the complex flows forward inside the nitrocellulose membrane 84, and combines with the coated mouse anti-human IgG monoclonal antibody and (or) mouse anti-human IgM monoclonal antibody when passing through the detection area, forming "(Au-HP-Ag)-(HP-IgG)-mouse anti-human IgG monoclonal antibody" or "(Au-HP-Ag)-(HP-IgM)-mouse anti-human IgM monoclonal antibody" conjugate and agglutination and color development, colloidal gold-labeled streptavidin combines with biotin coated with the quality control line to agglutinate and color development; when testing negative samples, the sample does not contain Helicobacter pylori antibodies, so that the immune complex cannot be formed, and only the quality control line C is colored.

[0037] Sample addition method: Take 10µL serum (plasma) or 20µL whole blood sample and add it directly to the sample well 3, and then add 100µL (about 2 to 3 drops) of sample diluent to the sample well 3. Read the result within 15 to 20 minutes, and the test result will be invalid after 20 minutes.

[0038] like Fig. 9 As shown, the test results are explained as follows:

[0039] 1. IgG positive: Two red lines appear at the IgG test line and the quality control line; this indicates that Helicobacter pylori IgG antibodies are detected in the sample.

[0040] 2. IgM positive: Two red lines appear at the IgM test line and the quality control line; this indicates that Helicobacter pylori IgM antibodies are detected in the sample.

[0041] 3. IgG and IgM are positive at the same time: Three red lines appear at the IgG test line, the IgM test line and the quality control line; this indicates that the sample contains Helicobacter pylori IgM and IgG antibodies and may be in the infection period.

[0042] 4. Negative: Only one red quality control line appears in the test window; this means that Helicobacter pylori IgM / IgG antibodies were not detected in the sample.

[0043] 5. Invalid: No red quality control line appears in the test window; invalid results should be retested.

[0044] The test kit 1 can be used for micro-addition of samples and detect IgG and IgM antibodies simultaneously, and is easy to operate and interpret.

[0045] How it works

[0046] Step 1: Pull down the button 5311 to move the movable plate 537 downward along the guide rod 536. The inclined surface of the guide groove 539 presses the guide post 5310 inward, causing the slider 534 to drive the hook 535 to move inward, so that the cover plate 51 can be rotated away from the test box 1, and the cover plate 51 is opened;

[0047] Step 2: Unscrew the nut 65 from the inner cavity of the test box 1, pull out the storage slot 61, take out the blood collection needle 64, prick the finger, use the pipette 63 to suck blood, and drip it into the sample addition hole 3, put the blood collection needle 64 and the pipette 63 back into the inner cavity of the test box 1, add diluent to the sample addition hole 3, and complete the preparation work of blood collection test;

[0048] Step 3: Push back the cover plate 51 until the hook 535 is inserted into the positioning hole 4, fix the cover plate 51 on the top of the test box 1, seal the sample adding hole 3 and the cover plate 51 with the sealing ring 52 to ensure the hygiene of the sample adding hole 3, shake the test box 1 to allow the diluent to fully dilute the blood, and judge whether there is Helicobacter pylori antibody by observing the color change of the judgment window 2;

[0049] Step 4, when it is necessary to disinfect the straw 63 and the blood collection needle 64, pull the right end of the lever 75 forward to cause the connecting rod 76 to push the pressure plate 74 backward, and the pressure plate 74 squeezes the rubber bag 72 to press the rubber pad 77 to open the incision, and the disinfectant in the rubber bag 72 flows into the inner cavity of the test box 1 through the conduit 73, passes through the mesh of the storage groove 61, and the disinfectant fills the inner cavity of the test box 1 to sterilize the straw 63 and the blood collection needle 64.
