國際認(rèn)可的標(biāo)準(zhǔn)

獲得的國際認(rèn)可保證了提供的微生物學(xué)檢測的結(jié)果是公認(rèn)的

原理

應(yīng)用酶聯(lián)免疫法，最后測藍(lán)色熒光（ELFA）抗原（細(xì)菌、蛋白）的檢測是應(yīng)用一種夾心的技術(shù)，包被針上有抗體包被，所測得的熒光與標(biāo)本中抗原的含量成正比。

測試范圍

用以食品及環(huán)境樣本中的致病菌包括：沙門氏菌、李斯特菌、單核細(xì)胞增生李斯特菌、葡萄球菌腸毒素、大腸埃希菌O157、彎曲菌、免疫濃縮沙門氏菌、免疫濃縮大腸埃希菌O157。

即可用試劑

VIDAS一次性即可用試劑分為
2部分：
　　 SPR，固相接受器，其內(nèi)側(cè)由抗體包被，此包被針作為固相吸管功能
　　 條形碼標(biāo)記試劑條，含所有所需試劑，取出即可用。試條類別由試條上顏色標(biāo)貼及3字母的標(biāo)志識(shí)別。

VIDAS and mini VIDAS : automated immunoanalysers

VIDAS is a multi-parameter automated immunoanalyser. It comprises an analytical module, a computer and a printer. The analytical module automatically performs all stages of the analysis, including printing out the full results. It contains five sections, each accepting 6 tests, and can handle 60 tests per hour. Thanks to its speed of reaction and sectioned architecture, VIDAS? is the ideal system for handling series of analyses and urgent tests. The computer module is used to manage and print out the results. It can handle up to four analytical modules simultaneously, giving the system a capacity of 240 tests per hour.

mini VIDAS is a compact version of the VIDAS system, with a built-in computer, keyboard and printer. It has 2 independent sections each accepting 6 tests, and can process up to 12 samples simultaneously.

The VIDAS technology is reliable in all situations, as confirmed by our operation mini VIDAS? on Mont Blanc.

With a range up to 70 assays VIDAS tests have applications in clinical diagnostics and industrial microbiological testing.

VIDAS test

VIDAS tests use ELFA technology (Enzyme Linked Fluorescent Assay), associating enzyme marking and fluorescence measurement. It is used on the VIDAS and mini VIDAS automated analyzers. Based on an inter-sample anti-contamination principle, VIDAS? tests are presented in individual, ready-to-use form. They contain a SPR and a strip :

the SPR (Solid Phase Receptacle) is the solid phase of the reaction. It is a disposable item, and acts as a sampling needle. This concept eliminates potential inter-sample contamination.

the strip contains all the reagents, ready for use.

At each stage in the immunoanalysis, the SPR repeatedly takes up the reagent and transfers it into the various wells of the strip, through to the final stage of the analysis. The last well is the reading well, where the final intensity of the reaction is measured by fluorescence.

VIDAS menu for industrial testing

VIDAS offers 8 assays for the rapid detection of pathogens in food products and environmental samples :

VIDAS Listeria, for detection of Listeria (validated by the AFNOR *)

VIDAS Listeria monocytogenes, for specific detection of Listeria monocytogenes (validated by the AFNOR *)

VIDAS Salmonella, for detection of Salmonella (validated by the AFNOR *)

VIDAS ICS, for salmonella immunoconcentration

VIDAS Staph enterotoxin, for detection of Staphylococcus A, B, C1, C2, C3, D and E enterotoxins
