Problems solved by technology

[0008] (1) Non-specific recognition cannot be distinguished according to the size of the molecular weight when analyzing the results;
[0009] (2) The operation is relatively complicated and requires expensive fluorescence microscopes, which are difficult to popularize in many primary hospitals and are not suitable for laboratories with a large number of specimens;
[0010] (3) The background in the fluorescence measurement is relatively high, and it is difficult to use the fluorescence immunoassay technique for quantitative determination;
[0011] (4) Experienced professionals are required to determine the results, and the objectivity of the analysis results is insufficient;
[0012] (5) Only qualitative testing can be performed, not quantitative testing
[0015] (1) Use 12×8 type, 6×8 type, 8×12 type or whole plate type 96-well special microwell plate as antigen coating equipment and reaction Containers can only be divided into 12 batches, 6 batches, 8 batches or the whole board for one-time use, and independent and single-person testing cannot be carried out;
[0016] (2) There are many types of reagents used in the determination, and each detection reagent must be filled with a reagent bottle, and each time a reagent is used, it is necessary to replace the suction nozzle to add to the microwells of the microwell plat...

Embodiment 1

[0095] Example 1 Reagent device 1 for detecting varicella-zoster virus antibody

[0096] Such as Figure 1-2 As shown, the reagent device for detecting varicella-zoster virus antibodies described in the present application is a long strip, and includes a base 10 with eight holes and a handle 20 at one end of the base 10. The sequence of the eight holes is arranged Starting from the end of the handle 10, there are sample hole 11, adjuvant hole 12, enzyme conjugate hole 13, substrate hole 14, stop solution hole 15, diluent hole 16, reaction hole 17, and dilution hole 18. Hole 11 contains the sample to be tested. Adjuvant hole 12 is for adding auxiliary reagents when required for detection (for example, when detecting IgM, add adsorbent into the auxiliary agent hole). Add enzyme conjugate solution to enzyme conjugate hole 13, and substrate hole Add substrate solution to 14, stop solution hole 15, add stop solution, diluent hole 16, add diluent, reaction hole 17 is flat-bottomed and ...

Embodiment 2

[0099] Embodiment 2 Reagent device 2 for detecting varicella-zoster virus antibody

[0100] Such as image 3 As shown, the reagent device for detecting varicella-zoster virus antibodies in this embodiment has the same basic structure as the reagent device in Embodiment 1. The reagent device also includes a number of support columns 50, and the support The column 50 is located under the substrate 10 in the reagent device, and there are more than one hole positions between adjacent support columns 50. The function of the support column 50 is to strengthen the mechanical strength and balance of the substrate.

Embodiment 3

[0101] Example 3 Reagent device 3 for detecting varicella-zoster virus antibody

[0102] Such as Figure 4-6 Shown is a preferred embodiment of the reagent device for detecting varicella-zoster virus antibodies according to the application of the present invention. Its basic structure is the same as that of Embodiment 1 or Embodiment 2, except that the reaction hole 17 is a detachable structure. The reaction hole 17 is composed of an outer hole 171 and an inner hole 172. The bottom of the outer hole 171 is provided with a bottom hole 174. The inner hole 172 passes through the bottom hole 174 and is tightly fitted with the bottom hole 174. Between the outer hole 171 and the inner hole 172 An anti-overflow cavity 173 is reserved. The function of the anti-overflow cavity 173 is to stay in the cavity if the liquid overflows during the reaction process to prevent contamination of the instrument and other reagent devices.

[0103] Further, the method of cooperating and fixing the inner ...

Abstract

The invention provides a reagent device and a method used for detecting varicella-zoster-virus antibodies. The reagent device has a long strip shape, and has a base body comprising 8 hole positions and a handle positioned on one end of the base body. From the end proximal to the handle, the 8 hole positions are sequentially a sample hole, an auxiliary agent hole, an enzyme conjugate hole, a substrate hole, a termination liquid hole, a dilution liquid hole, a reaction hole, and a dilution hole. According to the invention, based on a principle of enzyme-linked immunoassay, varicella-zoster-virus antibody is detected by using the reagent device. The method is an independent single-person analysis and detection method. The device can be used in cooperation with a corresponding specific analysis instrument. During a detection process, detection reagents or samples are injected by using a full-automatic precise dosing device. The device and the method have the advantages of automatic operation, precise dosing, high detection result accuracy, high detection result precision, and wide application prospect.

Description

Technical field [0001] The application of the present invention relates to a reagent device and method for detecting varicella-zoster virus antibodies, and belongs to the technical field of clinical immunological detection. Background technique [0002] Varicella-Zoster virus (Varicella-Zoster virus, VZV) has a spherical shape with a diameter of 150nm~200nm. The complete virus consists of a core, a nucleocapsid and an envelope. The core of the virus is double-stranded DNA with a small amount of enzyme protein. The core-shell is composed of 162 hollow tubular shell particles to form a octahedron. The outermost layer is the envelope, which is composed of fat and glycoprotein, and the antigenic structure exists in the glycoprotein. [0003] Chickenpox is caused when children are first infected with varicella-zoster virus, and the virus in the latent body recurs after some stimulation and causes herpes zoster, which is more common in adults and the elderly. Varicella occurs in child...
