Embodiment 1

[0043] Example 1: Such as figure 1 with figure 2 As shown, a cytomegalovirus and rubella virus combined detection reagent test card includes a card cover 1, a card bottom 2 and a test strip 3. The card cover 1 is provided with a sample hole 11, an observation hole 12 and an installation marking hole 13 , The card bottom 2 is provided with a groove 21 in which the test strip 3 is placed. The test sample application area 31 on the test strip 3 corresponds to the sample injection hole 11 on the card cover 1; the gold label area 32 and the nitrocellulose area 33 on the test strip 3 correspond to the observation hole 12 on the card cover 1. correspond.

[0044] Figure and Figure 4 As shown, the test strip 3 is provided with a test sample area 31, a gold label area 32, a nitrocellulose membrane area 33, and a water absorption area 34 in sequence. The test sample area 31 is a glass fiber layer; the gold label area 32 is provided with a test strip 3 On the upper surface of the colloi...

Abstract

The invention discloses a combined test reagent card for cytomegalovirus and rubella virus, which comprises a card cover, a card bottom and a test strip. The test strip is provided with a test sample region, a gold label region, a nitrocellulose membrane region and a water absorption region sequentially; and the nitrocellulose membrane region is provided with a quality-controlling line coated with goat anti mouse IgG, a testing line coated with cytomegalovirus antigen and a testing line coated with rubella virus antigen sequentially. The technical scheme adopted by the invention can test cytomegalovirus IgG antibody and rubella virus IgG antibody in the sample simultaneously and the total accordance rate of the testing result is higher, so the application prospect is wide. Compared with the detection of IgM antibody, the combined test reagent card for the cytomegalovirus and the rubella virus tests the IgG antibody; the IgG antibody can be carried for the whole life and is only associated with acute infection; and the accuracy is high.

Description

Technical field [0001] The invention belongs to the field of biological detection, and specifically relates to a combined detection card capable of simultaneously detecting cytomegalovirus (CMV) IgG antibody and rubella virus (RV) IgG antibody. Background technique [0002] Cytomegalovirus (Cytomegalovirus, CMV) is also known as cellular inclusion body virus. It is named because the infected cells are enlarged and have huge nuclear inclusion bodies. Cytomegalovirus infection is very widespread in the population. The adult infection rate in my country is more than 95%. It is usually recessive. Most infected people have no clinical symptoms, but under certain conditions, they can invade multiple organs and systems and cause serious diseases. The virus can invade the lungs, liver, kidneys, salivary glands, other glands of the breast, as well as polynucleated white blood cells and lymphocytes. It can be discharged from saliva, breast sweat, blood, urine, semen, and uterine secretions...
